This is the 4th version of my lego crawler. The first version was build more then two years ago. I’ve used RC4WD Rock Crusher X/T 1.9 Tires on current model. Other changes are:
1. The main gear ratio is reduced from 1/1 to 12/20
2. The linear actuator is used in steering mechanism instead of of worm gear. It lets to make the front axel simplier and lighter.
The cross-country ability has risen noticeably.
