We recommend using the M5 steel mounting screw to mount IG52 motors. We use these in our Custom Length IG52 DB Robot platform when we mount the motor to the chassis through two 1/8" thick plates.
This robot is a prebuilt 2WD All Terrain Robot (ATR) designed and fabricated in North Carolina USA. This robot supports our IG42 planetary gear motors.
This ATR robot uses custom length sides and 10 inch tires. We have included everything to make it ready to run including batteries, controllers, chargers, etc.
