This is a limited-edition version of the Fiat Abarth 1000 TCR Berlina Corse (Item 58721-A) kit with pre-painted, pre-cut body and wheel arches, great for not only beginners but also veterans of the hobby. The origin of M-chassis series history goes back to December 1994, and this series has been popular due to cost-effective kits with a wide choice of bodies, ease of maintenance and control for any level user. Enter the MB-01! The MB-01 chassis continues that tradition and allows six setups by choosing from three types of wheelbases, and front- or rear- wheel drive system. Its first body recreates the Fiat Abarth 1000 TCR Berlina Corse which was a car developed with high level tune-ups based upon the compact 2-door Fiat 600. The 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, rear-wheel drive setup. 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; low or high motor position can be chosen for rear-wheel drive cars. The 4-wheel double wishbone suspension features symmetrical structure and friction dampers. Unitized sections such as motor mount, final gears and suspension facilitate ease of assembly and effective maintenance. - Length: 322mm, width: 163mm.
