[MOC] RC Car Chassis - normal foward, 1/5 speed reverse

[TechnicBrickPower]

Hi All,

This is my first attempt at a car chassis. It is remote controlled with forward and reverse and remote controlled steering. What is different about this design is that it implements a special gearing mechanism that allows the car to drive forward at a normal speed, and 1/5 the speed in reverse. It uses a special configuration of differentials and a pair of ratchet gears to achieve this - however I did discover a flaw in the design after I built it.
