Wondering how to set up the motor pinion gear mesh with your Bully 2.2 Axles (Z-A0020)?
The goal is to set the motor pinion gear meshing is not so tight and not so loose. A trick is to use a small piece of notebook paper and slide it between the two gears, then push the gears together and tighten the motor screws. You will then need to spin the gear manually to extract the paper. This will give you just enough space to make sure there is not too much play nor tightness to avoid any backlash.
