FYI.
I did this a few months ago. It was on a hyper 7.

Almost the same motor only 550 kv. Emaxx CVD's in the rear drilled out to 8mm, dog bone in the front. Shaved the motor shaft down a little (like and 1/8"). Offset the motor to one side to center the batteries.

I the motor would get REALLY hot on 5s works perfect with a 4s. Just as fast as the gas guys. I never thermaled a mamba max on 4s with this setup.

The buggy would wheely on pavement.


Hope that helps.
