[MOC] Rock Crawler - 42114 C-model

[mic8per_]

RC Rock crawler. Features AWD drive without differentials using 69730 "Large angular position motor"(As it has realy good torque), Steered by L-motor, and springless suspension (concept by superkoala). Lack of differentials gives nice off-road perfomance, but the crawler has big steering radius due to that.
42114 C-model.

The suspensions are simply two linked pendular axles, so no U-joints are needed. The steering uses gears instead of u-joints, like this:

Except I use 2 thin 12t and 1 thin 20t for each front wheel and don't use portal axle, setup is same with mine... I neeed to think other.
