1920 Shaft size?

[captain harlock]

Yeah, actually they eat up some material from the shaft to reduce its size from 4mm to 1/8". And if you give the Mamba Max motor a look, you'll find that it actually has a 4mm shaft with a reduced size after it comes out of the bearing.

Also, you can actually ask Mike to bring you a version of the motor with this shaft diameter.

What turn are you gonna take? 6T or probably 8T?
