Acceleration and maximum speed comparison video with different TT-02B gear ratios

I focused on the gear ratio this time. We chose three gear ratios: high gear setting, low gear setting and intermediate setting between them. * 5.74: 1 (high gear) Focus on top speed (too much?) * 8.42: 1 (middle) * 11.38: 1 (low gear) Acceleration emphasis (too much!) Make extreme settings It is. It’s easy, it’s up and down and in the middle. With these three settings, the time and the maximum speed of 20 m sprint were measured and compared. The outside air temperature during measurement is about 10 ° C. Changing the gear ratio is like this! What? I think that it became the animation of the basic contents of it. It would be greatly appreciated if you could see it loose. The RC car used is TT – 02B of the same example as usual. I will write down the specifications easily.

【Chassis】 TT – 02B
【Extra Parts & Hopups】 * Rubber seal bearings (OP. 8) make full bearings * Many drive systems are replaced with Tamiya optional parts * Lower arms of front suspension are aluminized (YEAH RACING) * Front hub carriers are aluminum (OP. 793) * Upstream light is aluminized (square) * Rear suspension is lower alarm (Eagle) * Rear upright is aluminumized (OP. 793) * Front and rear damper is DF – 03 aluminum damper (OP. 926)
【Battery】 Tamiya Racing Pack 1600SP
【ESC】 Tamiya TBLE-03S
【Spur Gear】 70T (Normal) Low gear 68T (SP 1500) Middle 64T (SP 1356) High Geared [Pinion Gear] 16T (OP. 354) At low gear 21 T (OP 356) Middle at 29 T (OP. 1229) At high gear
【Gear ratio】 * 5.74: 1 at high gear speed * 8.42: 1 at middle speed * 11.38 : 1 (At low gear)
【Differential gear】 Front: Differential lock (OP. 1649) Rear: Differential lock (OP. 1649)
【Tire】 M2 slick tire 2 set (OP. 224)

The measurement place is asphalt pavement, Sand and pebbles are also scattered. After considering these effects, I intend to compare three kinds of motors relatively, as it is. Chassis specifications (total weight, gear ratio, tire diameter, etc.) are changed for each movie. For that reason, it does not make much sense to directly compare the displayed speed and time with the comparison movies you have already made, so please understand. Although it is a scary movie, thank you. *** External link *** Ameblo CAGEMAN ch.
