The Tamiya MB-01 Chassis. The compact, 2WD MB-01 chassis gives a choice of three types of wheelbases, and front or rear wheel drive system. This model employs a midship motor, and rear-wheel drive setup. Without removing the battery pack, motor, and R/C equipment setups from the center frame, simply change the attachment directions of final gears and steering linkage to switch between front- and rear-wheel drive; low or high motor position can be chosen for rear-wheel drive cars. The 4-wheel double wishbone suspension features a symmetrical structure and friction dampers. Unitized sections such as motor mount, final gears, and suspension facilitate ease of assembly and effective maintenance.
