42110 Land Rover Defender chassis, v1

This is my first attempt at motorizing the LEGO 42110 Land Rover Defender set. It features two PF L motors for driving and a servo motor for steering. I used non-original motors, which have higher RPM than the original ones, to achieve higher speed. The center differential is absent. The two-speed gearbox is shifted by a CaDA micro motor.

All functions work fine, but I’m disappointed with the performance and reliability of this version - the gears sometimes slip and crunch when driving over obstacles. Also, there is too much play in the steering mechanism.

Based on: MOC-102990.
