Team Deathly - first trainer bot

[Theo]

This is the same problem I have at the moment; the wheel bore being that ever so bit big. Tape has worked ok for me in testing, but won’t stand a chance in combat, plus the motors also just spin if I suddenly apply power. I’d suggest Banebots wheels but they only do awkward American measurements to my knowledge. Smaller wheels might work better if you can sacrifice the ground clearance, around 100mm would work better and reduce the motor spinning freely. If it’s just for testing, though, this setup should do for now but I’d advise you to fully modify them (locking down the clutch mechanism) for combat but that’s for another day.
