First, I feel the need to write a “disclaimer”, before somebody gets the impression that I dislike the SRB’s or Tamiya in general. I’ve been in love with the SRB since getting my first Sand Scorcher right after it was first released, have continuously been into SRB’s since then and have actively collected SRB’s by buying back from customers when regular parts supply started to get scarce in the late eighties. So I have quite a few and have of course bought the re-releases and I’m very happy that Tamiya has revived them. Still, I think it’s appropriate to present a few views that may not suit the euphoria associated with these models, and then end this text with the enthusiasm and hopes for the future that the SRB surely deserves after all! I know the text is pretty long, but it’s still a very “light” and quite superficial look at a long piece of Tamiya history. I have refrained from posting any pictures as other sites dedicated to Tamiya and RC are currently flooded with SRB-pictures anyway.

At the time the SRB was first released, there were no similar electric-powered off-road vehicles in the market. As I was just a kid at the time, I don’t have a complete overview, but considering that Kyosho just had the Peanut series and Rally-Sports series and Tamiya until then just the Cheetah/XR311, the SRB surely revolutionized the way people were thinking about EP buggies. Until the Kyosho Scorpion and AYK 566B were released, Tamiya had this new niche market practically completely on their own without any serious competition. Bolink tried to get a piece of this increasing market with the Digger 10. It was basically a 1/10 pan car with foam “off-road” tires, a pan car rear axle “hinged” in the middle with a universal joint to create some rear suspension and topped with a lexan body copy of the Rough Rider body, and that was about it.

As revolutionary as the SRB was, it had an innovative concept for its time, but technically, it wasn’t really well tested. Even back then, most (if not all) weaknesses were very clear to those who were actually running and racing these models, and it’s easily understandable why aftermarket companies like RCH, CRP, Kimbrough, MIP, JG and others could grow so rapidly and successfully.

Of course, though some companies offered components to improve the handling, durability improvements were most important and the main focus for those of us who ran or raced the SRB. Just to mention a few things that were considered weak points also back then.

1. Front suspension pins. Bent very easily and damaging the suspension arms when being bent.

2. Servo saver. The lack of a bearing made for high friction after some use, and servos at that time were generally not strong enough to overcome this high friction. Also, running the radio gear off 4 cells (especially when using dry batteries), the available steering torque was really inadequate for the rather poor steering mechanism.

3. Steering rods. Being 2mm and basically the same design as used on Tamiya’s 1/12 pan cars, they were much too weak for the 2+ kg SRB and in off-road conditions.

4. White “teardrop” ballraces in the front suspension. Very quick wear, especially if greased like recommended in the manual.

5. Nylon middle gear in the gearbox. Rotating at relatively high speed between a brass gear of the same dimension and a bigger nylon gear, wear was excessive.

6. Radiobox. Heavy and brittle and not really waterproof. Today’s hype of the “great waterproof” SRB is not justified at all, and mostly claimed by people who don’t have any actual experience with the SRB. Also, flex in the chassis plate and the loose wellnut in the rear hole, often caused the radiobox to get damaged even if not subject to a direct impact. Because of the brittle material, very small forces were adequate to damage the box.

7. Motor cover. Being the same brittle material as the radiobox, it would easily crack and disintegrate. Not a big issue for most who ran the SRB, but still annoying.

8. Rear cage. Unlike Kyosho, who chose a tough and flexible material for the Scorpion’s rear cage, Tamiya opted for a better looking, but much more brittle material.

9. Front bumper. Heavy and weak. Also, being quite expensive as a spare part, the tendency to break after just a few impacts was very annoying.

10. Dampers. Leaking badly even when new and being much too small for such a heavy model, the model was underdamped even with new and properly working (hypothetically) dampers.

11. Universal joints. Being of brass, wear was quick and excessive

12. Rear axles. Both the final gear axle and the wheel axles themselves would bend quite easily, and the weak universal joints allowed for a lot of slop and bending, which made the situation even worse as the “interaction” of bent axles and sloppy universal joints accelerated the wear and deformation of both.

The listed weaknesses and many more actual weaknesses were addressed by many aftermarket companies, sometimes well, sometimes less well. Also, a lot of money was made on aftermarket parts that weren’t of any actual benefit at all, but that’s the same for any model today too! Anyway, as much as I love the SRB and as nice as it is to look at and run, they were underdeveloped and inadequately tested by Tamiya before release. Many enthusiasts have a very romantic view of the SRB today, but fact is that Tamiya didn’t do their homework fully and properly, not just in hindsight. When you look at how much better the Kyosho Scorpion (and partially also the AYK 566B) were when released just a year or two later, although they had their share of weaknesses too, Tamiya’s excellent scale model skills, but also moderate RC-car technical skills, become evident.

As for using diecast parts, the typical understanding of metal being better than plastic doesn’t really apply. Of course, plastic material technology has improved a lot the last 30 years, but nylon was available back then too, and I guess that Tamiya could have made most of the diecast components of nylon instead, creating a more durable and lighter model. However, maybe nylon was more expensive than diecast parts, or maybe metal was considered superior to plastic by most customers, just like today? The use of diecast parts on early models make them easier to restore to a good finish today than modern models with plastic parts, so from a collector’s point of view, the use of diecast parts is now rightly celebrated. Also, the use of diecast parts on the Kyosho Circuit 20 series of GP buggies (and other manufacturers of GP buggies too), might have influenced Tamiya to use diecast too.

So, apart from fantastic bodies, relatively authentic suspension, a great scale look and founding a new niche of RC-cars, from a technical point of view, the SRB’s weren’t even great for their time and companies like Kyosho, with a lot more experience and knowledge about chassis design, quickly proved with the completely superior Scorpion that it would have been possible for Tamiya to make the SRB a lot lighter, more durable and better handling even without sacrificing looks. In other words, the SRB wasn’t THAT great, not even back then.

Currently, the interest in putting differentials into the SRB has caused some persons and even Tamiya themselves to offer ball differentials. But why? Tamiya could have included a diff with the SRB from the very beginning, but chose not to. Maybe to some degree for technical and cost reasons, but probably mostly because a differential wouldn’t offer any advantage for the average owner. The SRB was intended for loose surfaces and sand and even most GP-buggies didn’t have differentials at that time, and for today’s typical fun use, I can’t really understand why anybody would spend money on a differential for their SRB. I generally love improvements and hop-ups myself, but why spend money on something that actually is a drawback for the use where the SRB is the most fun?

Sure, when buggy racing got organized, Kyosho and others rightly started to offer differentials as an option. So, when the Super Champ was released and was intended for organized racing, the competitors already had differentials available, and the rear-heavy Super Champ made a differential even more necessary when running on a track. As such, I think it was a mistake not to develop a differential for the Super Champ or even the SRB after customers started to use them for organized racing.

In the early ‘80’s, I ran SRB’s with aftermarket differentials in organized racing myself, and still own some CRP differentials, but currently have none of them installed in my SRB’s as it doesn’t have any sensible purpose anymore.

By the way, when talking about the Super Champ, back when it was released (and even today), I couldn’t understand why Tamiya didn’t include any of the improvements on the other SRB’s. The better servo saver, tempered steel front suspension pins, better steering rods, brass middle gear and steel universal joints could all have been incorporated in the Rough Rider, Sand Scorcher and Ford Ranger without hurting scale looks and probably also at a very moderate extra cost. These improvements would have made the models a lot more durable and enjoyable. Difficult to understand, especially when considering that the other SRB’s were offered for several years after the release of the Super Champ.

Of course, in 1983 (when the Super Champ was released), Tamiya already had plans for the future and knew that the remaining life of the SRB was limited. For the fun market (not organized racing), the market dropped massively after the Scorpion was released and even more so after Tamiya released the much cheaper, quicker and more durable ORV (Brat, 037, Frog). By the end of 1984, only people with a special interest in scale models (almost nobody back then), would buy an SRB when they could have an ORV, Scorpion or other models at much lower cost and with a lot less trouble. As I was working in the business, I closely observed how the interest in the SRB dropped quickly, and in Norway where I lived at the time, the remaining stock of SRB’s was so unsalable that they were offered for about EUR40,- in the end, at roughly ¼ of original suggested retail price. Even at this price, it was hard to sell them.

As for the racing market, the SRB boomed and dominated the buggy class from the very start and until 1983, much with the help of the aftermarket business. The AYK 566B was a hot contender, but the aftermarket for it was always moderate and quite a lot of manufacturing defect issues (especially gearbox) ensured that it never really got well into organized racing. With the release of the Scorpion, the SRB got very hot competition. Being much lighter, better balanced, generally more durable and much better handling, the SRB would have been without a chance in racing if there hadn’t existed so many aftermarket parts for it. At the 1983 World Championship (ROAR, not IFMAR official world championship) in Anaheim California a heavily modified Scorpion won and more than any other single event marked that the days of the SRB were over as a competition model, even when massively upgraded with aftermarket parts. But then again, the Scorpion won against Associated RC10 prototypes with a very small margin, and it was evident that realistic scale buggies were about to leave the arena for the benefit of purposebuilt racers. With the release of the RC10, the SRB was finally “dead” as a model for organized racing, and at about the same time (early 1985), 4WD models would occasionally start to win races. Kyosho Progress and Hotshot being examples, and by 1986 replaced by the Optima and Supershot/Boomerang. Still, even with 4WD entering the scene and the superior Scorpion, it was the RC10 that really “killed” the SRB as a competition model, whereas cheaper alternatives (mostly from Tamiya) made customers loose interest in it as “fun” model. As such, the SRB’s lifespan in the market was limited to 4-5 years! Almost hard to believe now, considering its current popularity!

Talking about popularity, some of the aftermarket companies that offered parts for the SRB back in the old days have indicated that they will offer parts for the re-release SRB’s too, but so far, little is available, mostly limited to old stock of parts that didn’t sell well even back in the old days. I realise that there might be a small market for some aftermarket parts, but as soon as enthusiasts that have little experience running the original SRB’s realise that practically any hop-up for improving handling will be in vain, I fell confident that the remaining market will virtually be for “scale” details and durability improvements only. Making a profit on SRB parts to improve handling and performance will be a lot harder today than back in the early days. So what will sell well? Obviously, I don’t have a crystal ball, so I can just make some more or less qualified guesses:

1. Aluminium wheels seem to sell quite well already, and are offered by quite many sources, although a comparison of quality of several of them shows that sources from Far East offer the best and most consistent quality, combined with lower prices!

2. Reproduction stickers of the original SRB-stickers are of course popular as replacements for the “generic” stickers included with the re-release SRB’s and will probably remain popular for years to come. Also here I have compared the quality from several sources and quality is mostly disappointing, also from the sources that are often considered to be the best for reproduction stickers. If time allows, I will write an article for Tamiyablog soon, presenting the SRB reproduction with the by far best quality so far.

3. Bodies. To my knowledge, there currently doesn’t exist a single aftermarket body with acceptable quality. The lexan- and ABS-bodies offered for the SRB from several sources are so inferior to the original bodies that they aren’t suitable for anything but hard thrashing, but that’s not what the SRB is about, is it? 😉 I however hope that some of the Japanese manufacturers, which probably are the only ones capable of making bodies that could be real alternatives to the original bodies, may consider the market large enough to have a go.

4. Boxart style front bumper, rear cage and nerf bars are to some extent already available, and one of the best companies is about to release their versions. Personally I look very much forward to that and feel confident that they will remain good sellers for years, keeping in mind that the overall market is pretty small.

Some also offer chassis plates for the SRB, but I have yet to see a design that is significantly better than the original chassis plates.

5. For durability and precision, just like for the original SRB, I think there is a pretty good market for improvement parts for the steering mechanism. A pretty good cure that still looks pretty “scale” is using the steering linkage and servo saver from the Super Champ (like I do on all my SRB runners), but considering that these parts aren’t easy to find anymore, I would love to see somebody address this major weak point of the SRB.

6. So what about gear cover, motor cover and even radiobox? Well, especially the radiobox, even with all its flaws, is one of the things that has made the SRB so loved, and with the improvement of plastic technology and re-relase parts being easily available, I hardly think there is any market for an alternative box or radiotray. As for gear cover and motor cover, the diecast gearbox of the SRB, though somewhat better cast on the releases, still looks pretty rough and crude by modern standards, so in my humble opinion, machined aluminium covers look a bit out of place. Also, the original gear cover was never really a problem unless the screws were tightened too hard, so what remains for me is the wish that somebody will offer a stronger motor plastic motor cover. That said, I’m pretty happy with the availability and price level of the motor cover for the rerelease anyway!

7. With the availability of “small scale” dampers, I can hardly imagine that aftermarket dampers specifically for the SRB will sell well, and generally I think most will keep the suspension pretty original as it’s part of the charm of the model. I would love to see somebody offer tempered steel pins for the front suspension though and was in fact surprised when the Buggy Champ was released with “soft” pins, as bent suspension pins and the resulting crooked front suspension wasn’t at all considered “charming” back in the old days and hardly is even now!

8. Well, what do you think? Dummy parts to improve the scale looks maybe? Dummy airfilters? Dummy boxer engines? Scale looking floorpans? Sound modules? Light kits? Some of these items exist already, but the combination of excessive prices and mostly inferior quality surely makes for an opportunity of those quality-oriented enough and with a healthy understanding of the balance of demand and offer, to take a large portion of this market. Your ideas and views are very welcome and though we’re in no position to make any promises, we have already presented our ideas to one of the most serious manufacturers of aftermarket parts, and would be happy to forward your ideas as well.

Any way we turn it, we’re in for a lot of fun in the coming years! With the re-releases, dreams have again come true for many of us, but never being really saturated, at Tamiyablog we’re excited to see what Tamiya have up their sleeve next. A brand new scale buggy? Holiday Buggy or Sand Rover re-release? Keep dreaming, and at least some of the dreams will come true!

The 21st century: insatiable and powerful to further diversification

In the 21st century the battery RC 2400 as a successor to the 3000’s finally MH cell Ni-MH pack “V 7.2 Advanced RC3000MH Pack” (Item55075, 7800 yen, released in November 1900) appeared. Consideration of environmental issues from the European NiCD batteries banned the manufacture and sale of the essential use (such as special-purpose cryogenic environment) except that after three to four years and that a total ban was decided in the RC electric car in the world, Ni-MH cell migration and the flow is inevitable.
This is however, and the 4000 mAh and 5000 mAh, only five years ago, during the mid-1990s as an unimaginable appearance of a large-capacity battery is held road. In fact, between 2005 to 1906, the cell Ni-MH 4200 to 4300 mAh nominal capacity is reached, the RC-06 electric car for the first time as lithium polymer battery pack (5000 mAh) from the sale of Orion. In addition to 07 from entering or INTEREKUTO GP series from 4500 to 4600 in cell division has been announced. The page first published in 2002 is forecast at the time it is amazing to realize that the pace of development is frighteningly speed is it? High-capacity Ni-MH cell separator is the film is really the limit, but the shape is still lithium polymer is not standardized, so the future of the fluid. Orion standard size is smaller than the size would decrease capacity. Still, it is expected, circa 2010 to about 7,000 in 6000 to expand the capacity or even higher. Runtime race does not change as long as the battery capacity can be expanded, it devours its capacity goal as a new motor is always evolving. Power loss and motor fits into full development, will continue.

Behind these times, and they made tuned motor Tamiya’s first century as a “stock Dyna Run” came after the “Super T stock 23” series. “Oak bell for the end and irresolvable by motor type” to “stock motor” defined as the introduction of this site is that to be strange, but “black motor” since it flows from the tuned motor fine also, in that, a series of motor modified lineage included Tamiya.

Now, this “super stock 23 T” came in June 2001. Tamiya motor really is a new product in five years, is also largely inside evolution. The manufacturer has not been revealed, is being used in various parts of it, as long as other OEM manufacturers for many micro-projects in Sagami made that clear. JMRCA rotor is to comply with the provisions of 23 T stock diameter was 0.80 mm 23 T common single winding, 20 advancer in the same degree it is, as the first Tamiya motor adopted Type R (op.476, 2,600 yen), the standard adopted Super Stock Racing Type T (op.477 2600 yen) that is available for innovation.
The performance of the motor, motor laboratory already “18” is introduced in detail below. 23 turns is the same over the past 10 years between the “original T 23” RS-540 more than 30 percent more powerful than sport tuned plays. Such performance is up greatly contributed to the recent rapid rate of performance improvement of magnet materials. Magnet material for small motors, such as PC HDD motor for development, with almost every year since the late 1990s as evolution progressed rapidly and, thanks to the magnet for RC, stronger and more heat strong as a year out. In addition, brush and materials from a soft, high-performance, high-current to sink more easily. Instead, the brush is extremely short life, and 5 to 10 packs must be exchanged. Also, a soft brush also increases the amount of friction. Tamiya GP, qualifying only two minutes of time, “Darre heat” in the second half of the qualifying time will never run dry, not once did anyone think that the real problem now. In addition, over 4,000 T stock of batteries in 23 minutes 8 run, the motor is 150 degrees inside often exceed the bell to end shottky diods installed and the guarantee element temperature of 105 degrees and heat damage away from the motor, touring IFMAR rules modified ran 5 minutes 07 TITC’s Motor (Thailand international race), Code of solder is melted in the heat of an accident drop out Bell secondary end to your code you had to screw or not, although an extreme example, the recent story is pretty tough to come out to be more. None of this is the amount of current consumption and brush friction caused a sharp increase. Calorific value and durability of high-performance tradeoff is that the relationship is known While it is a mixed blessing.

Now, “Super 23 T stock” has been out of the same end-use Bell Kang possible to disassemble and “11 super modified motor T” (op.485, 5,200 yen, released in October 2001). Bell was 5 × 4mm Super Stock Racing end, the same standard specifications. Roll Double-11T (perhaps unknown wire diameter 0.85 mm) and the high-end model as the “TRF acto power tune” Since the very first time in eight years have become hot model. As a little story, as spare brush, is still a fixture at the time was not part of “round-T” sign brush (op.581 later years as a staple) has been included, and so do nearly 10 percent more powerful.

Was a little disappointing, Ni-MH cells spread in the world touring car no-load 40,000 to 50,000 RPM, 540-size motors to test the physical limits of the mainstream and is thicker motor, which becomes 11T is a pretty half-hearted setting, in the end there was most active in the field. Tamiya GP but only a 1 to 2 times only did I have had the opportunity to participate. And, surprisingly thin and torque, turn 11 and 13 are essentially saying turn much power it was anticlimax. Eventually, 02 H dyna tech exceed “the strongest motor Tamiya” star performer, released in December 2004, “Transpeed MS (9T),” had to wait.

“MS Transpeed” series, in July 1999 Tamiya is “TRF414X” released in America, “the title game of the World Touring Car Abduction” Works goal since returning to work flow, the highest peak pure motor racing. ISTC 2004 “3600 cell battery 5 minutes +6 race, the” single optimized format specifications Item 49347 T 9 is Dec. 14, 1904, 06 experts JMRCA class of “Cell 4 minutes 8” format of more than 4200 Using cell premise that the specifications of the single Item 49386 T 10 is March 29, 1906 has been released. The biggest feature is the Team Orion has developed a “V2 technology” to be known as Bell & brush-end technology to set point.

“Technology V2” is the brush at a 45-degree unsold placed in a V-shaped layout adopted for the brush shape, “cylindrical” adopt an entirely new form of the power and fuel economy, the end of the cooling efficiency Bell raised new dimension to a series of end-handed Bell system technology. It is just a “sham” that is not, Mark Rheinhard players in the 2004 ISTC TRF415MS victory to prove it has been sufficient. However, the actual visibility of the race earlier scene, circa 2003 from Orion already have OEM and the end-V2 is equipped with a bell in a series of motor input, and have become more popular.

04 to finally end of the year “Transpeed” issued Tamiya, motor OEM V2 series as a group in the last rounds. Fixed price of 12,800 yen and the record for one sitting Tamiya motor repainting so expensive, as it was used Tamiya GP because it is not OK. First of all, this motor is premised on a high-end chassis (especially TRF415MSX, including the latest model) is currently active in the field is extremely limited GP Tamiya that it is also the high price of motor supply is also limited because it is being. At this time, GP Tamiya inconsistent with the use and the judge may be. From circa 2006 brushed motor is gradually beginning of the lifting of the ban, since 07 is now completely mainstream brushless with it, now active in the field of MS Transpeed virtually disappeared state.

JMRCA Touring Car in 2006 is a Class 4 cell expert eight minutes to introduce regulations that because, since the use 23T stock motor modified motor sport classes and class expert in the use of the needs of the growing divergence. Tamiya, the HV 3300, and lasted 3600HV “immediately after the release of the latest cell products to” a stream is lost, released in May 2006 by the latest battery pack is a very late second-generation cell technology to the GP3700. Tamiya GP in terms of actual operations as well, since November 2006, a mini-class sports, the traditional “zapping until 2400” to strengthen the regulation of the battery, released in July 2006 SP 1600, specify the battery pack “detune” make up phenomena. Sales in the bold decision, I think, is a user-specified low battery is very welcome. Sport Tuned motor to 540 degrees, in 1600 SP battery performance is sufficient.

Tamiya GP motor to be used as well, “two steps drawn from the high-end” “Super-stock”. Since its release Tamiya GP motor used in the highest class of 23 T stock, the style is completely settled. In addition circa 2004 from the fixed-gear ratio rules also phases, and the further condition of equality and promote the entry cost of suppression.

Nevertheless, the battery is more powerful every year, which is the Intermediate class participants in the race’s 23 T stock situation is uncontrollable power is out. Still, the “under” and that motor sport tuned only the Kole Kole is involved in the short-lived brush from the performance and roses and with a lot of points from Tamiya fans unpopular it was also a fact. Also, a little away from Tamiya GP light look at the demographics and trends of the recent turn of 25 to 35, rather than the number of low-turn tuned motor (stock motor replaceable brush, etc.) have realized that selling within PHP. Especially noticeable is the “drift” Tamiya motor to buy a multi-user applications rise. These new users because of the spread of the traditional, 540 and Sport Tuned area has been covered 5 × 4mm motor brush opt to release them as there have been.

GT Tuned
Such has emerged from the background of the new turn of the 25-turn made a number of criteria, “GT tune,” 5 × 4mm Tamiya Motor 27 specifications of the brush as a primer for the new standards and tuned motor “GT Tuned”, Shizuoka Hobby 07 more have been added in the show’s 28-turn “Dirt Tuned”

Type BZ
Meanwhile, the stock of the fast-evolving 23 T also update progress on the spot. July 2006 is “Type BZ” appeared. It will continue in 4500 to 4600 and appeared in 07-degree battery JMRCA season from provisions in the revised specifications Super Stock Racing motor advancer stock liberalization is set by the new model has emerged to support it is not a mistake.

That Dirt Tuned both, “Super Stock”, “GT tune” “Dirt Tuned” “Light Tuned” a series of line-up completed by the GP Tamiya is quite used to reduce the motor went smoothly. The kit included 540 motor SH/540J as it will remain, for some time now, these motor GP Tamiya “motor control,” so as to play an important role.

GP Tamiya standard specification motor as a long-term change is not expected to “tune GT / Dirt Tuned” series and the race scenes to suit changing trends, “Transpeed” and the series “Two polar differentiation” will increasingly it would beat (which is not anything wrong). To fill the gap in the form of “Tamiya GP in the high-end” as a class JMRCA sports consciousness for the needs of people with years of evolution “Super T stock 23” system has expanded in the future to get interesting again feeling . Already former “2 WD acto power” is beyond the power and where it will be up to? And Bell’s end advance liberalization and the real difference between the motor is no longer modified (bearing only have different specifications), the specifications of the rotor variations what comes out of deployment?

1990s: Diversification age

Modified motor “third wave” had come in 1993 or later. Before that, from the late 1980s through the early 1990s “boom F1” Were not, but here is used solely SUTOKKUMOTA 540 type. “ROAD WIZZARD” to “F101 chassis” with the development of F1 GP Tamiya popular categories and classes and the beginning of the EXP unlimited weight class is, as it was nearer 930 to 950 g What ridiculously lightweight machines also being tailored, modified motor once the “fifth wheel”. Even DYNA-TECH 01 R, Power HAARI spare as he feels, is hard to master. Later, Tamiya Japan starting from now when all classes are now more than 1000 g, in any case focusing on performance improvement, and the main shaft and chassis parts to replace carbon materials, or cutting, such as “lightweight “. Battery performance is improving year by year it began, the Power 540 “sports EXP also driving satisfaction” was possible. The per the RC kit now lost part of me. “Lightweight, simple, fast enough 540 kit” and want to be resurrected. . .

However, the loop is also F1 boom, and then boom in the touring car, the weight IKANSEN 1600 g (then revised in 1995 to circa 1500 it became the provisions g) burden, and provides complete power shortage of 540. In order to obtain satisfactory performance review modified motor. Battery capacity also increased from 1400 to 1700 also reduced the frustration runtime.

The flow from that first came out, “ACTO-POWER” series. The motor, and finally Tamiya, even as a general-purpose brush thoroughly entrenched in the general “5 × 4mm brush” has been adopted. Ave!
2 WD ACTO-POWER First came out of the race for two open buggy WD “DYNASTORM” has been developed to take the double-pink cans 0.75mm14T “WD ACTO-POWER OFURODA 2” (op.122, 4800 yen, 92 Nov). 0.70 mm15T double followed by “touring ACTO-POWER” (black cans, op.153, 4800 yen, November 1993), 0.70 Double mm17T “ACTO-POWER Formula” (op.154, 4800 yen, 93 Nov) appeared. And this time, the battery is also revamping the capacity up “SCR 1700” (Item55056, 5,200 yen, released in October 1992), was later “ultimate” enshrined “SCRC 1700” (Item55062, 5,800 yen, 1995 March release) appeared. SCRC is particularly 1700, 1800 and the actual discharge capacity 1900mAh and ensure the discharge characteristics of excellent goods unparalleled in the past. Actually this “SCRC” cell type, cell battery sanyo industrial catalog is the first “RC exclusive goods.” In particular, the first year of production, the so-called “Z Damas” extraordinarily good performance, after years of treatment with a lot of this is zapping performance from the “difference in battery performance by different lot”.

“ACTO-POWER” series is the “line-up purposes, according to a prepared”, in other words “to deal with diverse needs,” the point. Already “TEKUNI” series in the rotor to ensure compatibility, “DYNA-TECH” opt-series set in the form of the rotor was not groundbreaking, but “ACTO-POWER” one step farther, separately from the package NARIMASHI hoop. That market has been growing that? Come to think of it, these days, the kit will be released in the number of variations of the body in the form of increased rapidly increased. Overseas exports also grew.

However, in ACTO-POWER, in the form of limited production spot by selling “TRF ACTO-POWER tune” (Item49567, 8000 yen, released in December 1993). Ostensibly for buggy, but in the first place, leading to the 1992 is being developed around a prototype buggy “TRF411X” according to the TRF’s activities Works made goods. Double-rotor winding is 0.8 mm and 12 T H 02 DYNA-TECH high spec since. Magnet also strengthened by the opt-10 H 02 DYNA-TECH rotor specification is not the enemy, but as a normal state of TAMIYA MOTOR power highest level in history.

TRF is a brush 411X Cheung said at the time boomlet, 5 × 5mm, the so-called Big & big commutator combination brush. Bell is also in the luxury end, cutting out the aluminum. Big commutator, ig brush, cutting aluminum at the end of Bell’s first model is adopted. Kang also encourage special cooling fin processing Special items were seen. While the price of 8,000 yen SURPRISE! Choicest hand-rolled motor 5000 6000 era might have bought the yen,! Rotor winding machine! Works of the bubble economy period just bear close resemblance to the motor design, but also anachronistic is downright disappointing. Collapse of the bubble economy, as long Buggy boom only mania, TRF prior to the release of motor buggy race fields were extinct, and even buggy Tamiya GP New Year’s race is only the beginning of the year already do not pay any more and who is gonna use this? Ultimately, the only Tamiya GP class also uses Gr.A was abolished in 1995, and to further open up cross race in the Big brush use is prohibited, age 95 is the big brush one sitting out. Tamiya eventually brush is a staple in the replacement of items that are not disclosed. So, really useless and motor BABURI become is also disappointing. In the past TAMIYA MOTOR was not planning products?

That, too, even after this funk without getting new products out. At the end of 1995, the newly-built SHINNAGOYA, “Special ACTO-TUNED motor M” and “DYNA-RUN” series begins.
“Special ACTO-TUNED motor M” commonly known “M tune” (op.251, 3,000 yen, released in December 1995) is a small lightweight chassis MINI COOPER for M, keeping in mind the length of normal rotor type 540 1 / 3 truncated, motors and overall length almost half of the 540 types of special motor. Normal motor and the motor is not a simple comparison, the rotor is certainly a single 0.65 mm T-22 was winding remember. The motor was decomposable, bearing oilless to reduce the cost of the combination is rare.

“M Tuned – on” is a small, lightweight, thin torque motor minutes and will be easy to property, changes to be able to advance, reverse motor used in the M-02 chassis to be used, such as point Woori. The aim is as much for the goods but was, however, the heat capacity is smaller in size commensurate Know in the end completely motor can opening bell and cooling performance is not zero, then immediately travel to heat happen, motor nuisance. But Tamiya GP season is about 2 to M-Class chassis and EXP are banned, M Tuned also unavailable. Until the 2002 model was left catalog, but now, people who are M chassis, I have almost forgotten?
Meanwhile, the touring car for “DYNA-RUN” series at the time, efforts have been 1 / 12 on road awareness and advocate strongly for it was “short stack” of the specifications of the rotor, which features were adopted . This is the rotor to fill the full length of the light, so that the rotor torque also weak finish by a strong magnet motor to be easy to finish rolling, to improve throttle response, the aim experience.

Lineup of the modified “super touring DYNA-RUN” (short stack single T = 15) (op.263 substantially equivalent 13-turn, 5,000 yen, and released in June 1996) and the type of stock “DYNA-RUN stock” (short stack Single real 20T = 17) (equivalent to turn op.272, 2,500 yen, released in October 1996) has been put in two types. Both are basically bell-end “M tune” common, Couling bad omissions, the brush is dry and easy to change design, “ACTO-POWER” bell-end precision machining is worse than it is regrettable. Frankly, the less popular Very poorly. Others have no choice but to reluctantly use anybody.

DYNA-RUN system, the rotor length is shorter minutes by filling an empty space cooling fans, and the forced-cooling device is also equipped with the feature. The concept itself is cooling fan, Johnson has already made TAMIYA MOTOR as “H DYNA-TECH 02”, but there is a proven recruitment. But fans DYNA-RUN system, shape issues and the lack of attention to air flow, such as the cooling performance is not necessarily expected to have had lamented that point. After all, Bell and end the “hole” is almost not open. Other side of the hole is open, the Air “exit” is not in the “entrance” is not quite so end up in the air in a motor only. Not just mean more losses, is it? Why is that kind of nonsense design, is still a mystery.

In the performance, “stock” and “super touring”, as the aim indicate, in response to the throttle work smoothly handling Sato Yasu well-balanced power to the finish, and to adopt a new brush (also sold separately as Racing motor brush op.307 by Mark M, T Mark after the former stamping modified brush) coupled with high performance and good performance. Consequently, but Tamiya GP touring as a spindle motor for the summer of 2001 “T Super Stock 23” series will come to a fairly long-term use.

Another series of these particularly notable in the motor system, “BURASHIDANPA” TAMIYA MOTOR introduced as the first point. BURASHIDANPA is the leading Japanese motor tuner, as invite eminent emerging as a manufacturer of motor activity started from age 93 nagoya Singh was introduced ahead of competitors, the company’s motor “Uri” and it was one of mechanisms. “Damper” says the so-called shock absorber to the recall should not. Bottom spring-loaded brush from the brush with a brush holder coercive force, to reduce the commutator with butter and stabilize contact with the brush holder and improve adhesion of the conduction efficiency of the device. As photos of the brush holder of a thin stainless steel sheet to the bottom of the peg, which cleaved into a little function as a spring board to wake up let them. The idea is simple, but can not dumb. – The performance was more favorable because it is obvious, since the micro Sagami OEM supply will be from 5 × 4mm motor brush with a “natural” equipment has become today.

Mid-1980s: Tamiya and motor-wave decomposition

Now, after several years, I was not very far away from the RC is detail, as might be expected, BLACK MOTOR specifications about the escalation of the year obsessed with 1 / 12 in the visitor’s Racing also reached that limit the height of the December 1984 finally, MABUCHI and joint development of the race only 8 minutes of high-efficiency “RX-540SD TECHNIPOWER” (sp.225 the 4500 yen) will be released. Both support shaft bearing, complete decomposition formula can be adjusted in advance of the first model. Next March 1985, the number of characteristics that turn a mild “RX-540SD TECHNITUNED” (sp.230 the 4500 yen) will also be released. This is the epidemic showed signs of the buggy, especially WD 2 machines in mind to use as a motor was released. The TECHNIPOWER TECHNITUNED and is the same type as MABUCHI, Tamiya and differ only in the part number so suspicious. Turn catalog number is not listed, but after some “TECHNIGOLD” T 21 single winding, and that the 21 TECHNIPOWER T, T TECHNITUNED at 23 degrees it was in (Single Roll it is verified). Diameter of the wire, but the appearance is about 0.70 mm.
But that time is still of RC motor parts, I like the versatility of most of the parts are no longer exists. Each manufacturer has been common in the procurement of parts I, and the rotor magnet around parts of the bearing, which was not only much. Bell and motor end, brush, brush spring, and each maker has been designed to own fancy. Naturally the high cost of production, 20 years from now at around 5,000 yen before, it is now reduced to a value of 10,000 yen to 15,000 yen worth of goods at the time the user is not purchased. . Then I, like jewelry.

Indeed, Bell and end around the middle of the magnet in part to build up long-bis motors, it is hard to note a mechanical mechanism, and is now fond memories. Now, any manufacturer the “visible parts” only to change the color and design of the fine parts of the generic parts are just a combination of a lot. And the price is pretty cheap now not to complain, but also the split-high-end model is also completely gone, press a piece of them, “boring” I think the only writer?

Late 1980s: motor age

Times have changed, the world is 1 / 12 Racing ON ROAD center is out of the buggy whip to start selling. “The four-wheel drive mini” boom coupled eginning. Era, the so-called “bubble economy” in the middle. In the middle to late 1980s, after the roof of the city’s department stores buggies there is a TV, “RC Tamiya Car Grand Prix” and other TV programs are aired, leading to a boom. There was an atrium of a building in Shinjuku NS (vaulted Square) to create special courses held and magazines for children and RC model is the tie-in TV advertising CM which was, I tell, who believe that now? But there are certainly times that. Definitely a “radio-controlled era” and also likely to put the money to use as a luxury product planning.

Tamiya in March 1988 “AVANTE” machine TRF release form (avex four years ago from the TRF), this year’s eighth JMRCA A in Japan and to enter into serious action activities Works This also started on time (TRF then “DYNASTORM” released after age 93 with a lull, but since 1996, 1 / 8 GP BMT fought race in the series and TRF404-414 development activities you know is resumed.)
The unprecedented four-wheel drive mini-boom, Power is expected to intensify competition. However, the battery capacity is still “1200 mAh” remain. SC cell types (General Standard cell) only. Early 80s qualifying time 45 seconds (!) Was battling JMRCA1/12 nightmare Racing is competitive with power came again. Blindly raise the motor power and runtime only only three minutes away from making a dilemma.

This approach quickly resolve for a period of time as the mid-1980s, has spotlighted the “V 7 cell pack 8.4” battery. Tamiya, too, “released 10 Planning Tamiya RC car,” Kraft’s moon buggy by Yura design, “BIG WIG (Item 58057, 25,800 yen),” released in July 1986, while “V 8.4 TAMIYA NI CD Power Gold (55025,6400 Item yen) “to release them. In addition, the motor is also included with the new V 8.4 as compliant HIGH POWER MOTOR “RX-540VZ TECHNIGOLD (sp.290, 5,000 yen)” to develop. The following year, in August 1986 from spare parts sold separately as also started. The rotor of TECHNIGOLD is 21-turn, 0.8-mm single.

Been released so far made a series of MABUCHI motor is essentially all of the parts are compatible. The final model, and 8.4-V battery “TECHNIGOLD” exchange theory, “TECHNIPOWER / TECHNITUNDED performance of brush” notices have been, and earlier TECHNIGOLD Two models of the brush is different materials (for TECHNIGOLD Perhaps it is more soft), the hardware is compatible with the same shape. Rotor, the wire diameter and the number is of course different from the wound, but was diverted because of the same size. This is around, but I also make custom MABUCHI model.

While all of this was going on, in 1987, Japan’s F-1GP back from Tamiya according to the “ROAD WIZARD” T-99 chassis and the new Lotus dipped Williams FW11B body kit released. F1 was boiling of a sudden boom.

R DYNATECH 01 F-1 model at the time, released at the end of the seventies, “Tyrell P34” “JS9 Ligier” to the first and second generation of F1 chassis compared to the lighter side, too, in terms of driving performance lot nicer, and even beginners Power 540 is a bit much uncontrollable, fast enough to have fun. Still, more power and high-speed has been increasing demand from users, which came out in response to that, “DYNATECH 01 R (op.1, 5,500 yen).” This is also the custom of MABUCHI goods in the name of the company MABUCHI “RX-540VS” now.

Oh, op.1? Yeah, the memorable “HOP UP OPTION” This is the first issue of Motor me know. Opt hop’s history is also up, with a motor, you know?

By the way, “DYNATECH 01 R,” rotor “configuration option” is the first thing that is striking out. 01 R DYNATECH standard diameter of 0.90 mm T-19 was a single roll of the options as 1.00 T 17 mm diameter are provided by a single winding.
Until then, the Member Works (TRF) and JMRCA participants to support the rotor at the scene bespoke specifications to be supplied as was the case, but such cases are generally not marketed. These “The race unless” special motor distribution or distributed at the scene, the enthusiasm, excitement and buggy boom, rather than now become more radical as it was (and already history back to late 1970s Works only “Special Motor Japan” does not exist were it). The RX-540 series, the name was different, “TECHNIPOWER” “TECHNITUNED”, the rotor is incompatible because this is essentially to opt around super rotor was like setting But from the beginning, as the opt out had not.

This time, the batteries finally wave of technology innovation. Generic years has been used for long-SC type of cell was released after 10 years after finally abandoned by the new large-capacity cell SCE appeared in 1700. Tamiya, “EX 1700,” released in November 1987 as being (Item55038, 6,000 yen).

However, the SCE has repeatedly recharge cell weak and discharge characteristics as a second half loaf, which becomes not necessarily suitable for RC. Therefore, large current discharge voltage can be sustainable in the end “type SCR” has been developed, “SCR 1400” (Item55051, 4,400 yen) as. 1990. As you know from the convention space, capacity at the expense of the discharge voltage drop suppress cell structure shook her direction in design. However, the actual usable space travel at the last minute pile-up celebrity, SCE 1700 and changed so much.

On that occasion, NI CAD BATTERY market, Matsushita Sanyo batteries to challenge the monopoly to begin, RC racing, “Panasonic” is gradually began attracting attention. “1400SCR” an end to this dispute, were sanyo Weapon is killer. Consequently, “SCE 1700” and “1400 SCR” appearance brought the NI CAD BATTERY “competitive capacity / characteristics competition” is the beginning of a new battle, every two years since “SCR 1700” “1700SCRC” “2000RC (Tamiya Pack is rejected), “” RC 2400 “” 3000MH “such as how new products come out,1990s and the development of competition will not plunge.

02 H DYNATECH Now, these large-capacity battery to the full benefits are received, after all motor. After all, turn to reduce the number of more powerful runtime is not able to maintain, over the years more and more extreme motor came out. It symbolized an era of monumental model, in November 1989 have been released as HOP UP OPTION “DYNATECH 02 H (op.44, 6,000 yen).” This is after, “2 WD SUPER ASTUTE (August 1991, Item 58097)” and “Evolution TOP FORCE (released in June 1992, Item 58107,3 18,000 yen)”

“DYNATECH 02 H” is more than 1400 large-capacity battery is premised on the use of the cobalt-containing rare earth magnet at the time of the highest level of luxury to be adopted, 0.65mm diameter of the rotor winding 13 Double T, still fully accepted in specifications emerged. What is 0.70 mm diameter wire OPTION ROTOR 10 Double-T! NI CD BATTERY was the highest level for the specs, the motor including “unlimited rotor (outside articles are OK!)” Fought over the rules of Tamiya GP Gr.A Touring Car class in the summer to become the battery Connector has dissolved! It is also sometimes seen as an accident. In those days, the PL (product liability law) was not because of the accident should be the responsibility of users, manufacturers and the percentage of your stance on this hot carefree motors could release it. Could nostalgic era of peace.
DYNATECH spare brush DYNATECH 02 H 02 H 02 H-opt DYNATECH The motor rotor is a strong sense of its own off-road driving to the end of Bell & Design adopted thanks to the brush, the brush is how 1,000 yen spare! On the enormously expensive goods. Akira Hiroshi just came at the end of the era of “Battleship Yamato” state. MOTAKAN, still making luxurious three-piece structure. Consequently, the last three as TAMIYA MOTOR piece motor structure. This excessive cost can go up to the user with no Haz, buggy boom will soon decline. Separately DYNATECH Tamiya and H-02 is not due. . .

“DYNATECH 02 H” Another particularly notable is the first motor Tamiya, except MABUCHI MODIFIED provided by the manufacturer of the motor. Johnson’s company in Hong Kong manufacturers. Johnson, speaking of the now-compatible 540 so-called “motor Johnson” will be known in the 1980s for 540 types of buggy boom race is not used because it is not, and then it is either “DYNATECH 02 H” Johnson, the company discovered by that many people?

But Johnson also is a world-MABUCHI after leading maker of small motors, and 540 types of motors since stabilized supply to the secondary source (alternate source) has been trading as it is you know below. “Johnson motor” will be included with the kit to become the first place? NOKI did, “Blackfoot” Big tire system as a kit included with the motor, 540 S want is a bit more powerful motor for the “special motor “ostensibly in the game like it was the beginning.

By the way, this is like a high-end motor it will continue year after year, the basic specifications of the 540 motor was basically the same, the gap between the power on the other hand is open. 80s line-up kits at the end of that time, especially at the time buggy motor to mainstream it, which include 540 for the introductory model, the motor system DYNATECH include a net after two minutes in extreme racing model been. However, many users to buy a car Tamiya introductory who just bought a net race model, the spare hand it is a high-performance, and quite a few cases. A little bit, meek performance in the 540 from the high-power motor MODIFIED want has been.
Meet these demands is born, “SPORT TUNED RS-540” (op.68, ¥ 1500, October 1990). This kit is included with the motor as “AVANTE 2001” (Item58085, released in June 1990, 26,800 yen) first appeared, followed by the first bullet C Series car chassis “Mercedes-Benz C11” (Item58088, released in November 1990, 13,000 yen) was also adopted. Original “AVANTE” “TECHNIGOLD” in the price of equipment three 2001. Also, “Group C” series is a gross weight of 1,200 g F1 model and heavier than the 540 offers power performance is somewhat dissatisfied. “SPORT TUNED” Tamiya assortment of motor MODIFIED indispensable product has been a long seller. Probably already MODIFIED Tamiya’s largest motor has been a bestseller in it. Life is short brush, Darre Magnet is easy to heat, and a lot of criticism might also say, a few decades before 5000 1500 yen available now, the impact is substantial, it’s big.

It is superfluous, “SPORT TUNED” is a diameter of 0.80 mm T-23 single winding. DYNATECH 19T just 0.90 mm of a single roll of 01 and R 540 S / SH 0.65mm 27T single roll of the intermediate and specifications. This, “a reasonable person in a high-performance primer” which was obtained or how barnacle to the specification later this basis, Japan’s distinctive “T stock 23” was born in JMRCA Touring Car class sports and other provisions also been adopted. As a result theory is just, lasting masterpiece TAMIYA MOTOR history, and they would say.
