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?

[Sylvester]

Gonna try 6t.

[captain harlock]

So you'll be near 38000rpms and that is quite similar to a 11T motor. Start from 19t pinion and I'm sure you'll hit the sweet spot with a 21-22t pinion.

This motor should be crazy! Hope she runs cool without heatsink (limited space for a heatsink in b4.)

The 1930 pushed a emaxx around with out alot of heat issues. I sure it should push a b4 no prob.
