We recommend using the M5 steel mounting screw to mount IG52 motors. We use these in our Custom Length IG52 SB Robot platform when we mount the motor to a 1/8" thick plate.
This is a SST tracked robot platform and is equipped with 32mm motors, a motor controller, and Spektrum remote control. This is a rugged robot platform. By default, the treaded robot handles up to 5lbs of additional payload and travels 50 ft/min.
This is a custom tank that we built with powerful wheelchair motors. The platform has 6 inch wide treads allowing this robot to navigate the toughest terrains.
