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 is a 1.75" x 1.75" x .125" thick aluminum plate designed to mount our IG42 motors.
This is a Pre Built direct drive 4WD base Programmable robot kit that uses Nexus mecanum wheels and hubs. Its a Arduino robot platform for indoor robotics. It can vector in any direction.
