★The 2WD BT-01 chassis gives a choice of two types of wheelbase, and front- or rear-wheel drive system. Without removing battery pack, motor and R/C equipment setups from the center frame, simply change attachment directions of final gears and steering linkage to switch between front- and rear-wheel drive; front (FR) or midship rear (MR) motor position can be chosen for rear-wheel drive cars. The 4-wheel double wishbone suspension features symmetrical structure and friction dampers, and unitized sections facilitate ease of assembly and effective maintenance.
