The MINI-Z RWD MR-04 series replaces the MINI-Z RWD MR-03 series. The MR-04 version RWD chassis is equipped with a revamped steering system that features optimized geometry and tighter clearance between moving parts. Also, the lower CG enabled by the lowest possible battery mount position ensures faster cornering speed and less chance of flip over. The RX unit is equipped with expansion ports for the optional gyro unit (MZW711) and LED unit (MZW429R), and the gyro effect can be adjusted by turning the small volume on the RX board. Comes complete with the KT-531P transmitter and full ball bearing specification, the MINI-Z RWD MR-04 provides users with higher value at the same price range.
