That thing is massive. Not really what you want to do a buggy. I would go with a 53 series axi, similar to what sike used in his direct to diff revo. Or one of the scorpion motors.

I was wondering if it was viable for anything really. Wasn't planning to use that in a buggy hehe. :P

Also, are the outrunners with the rotor sticking out both ends called something different?

I know this probably isn't that plausible, but just throwing ideas around, for an in-runner what if you could somehow mount the rotor to the shaft with a shock absorbing design similar to a rubberband/o-ring prop-saver on electric planes? It would have to be much tougher than a rubberband or o-ring, but you get the idea.

I hadplanned to do someething like this to the area where the motor mounts to the motor bracket. Thus the driveline shock would be isolated right at the motor.

if you have access to cnc just down size this and add a collar to contain the rubber under high torq...or something similar. I use to maintain 90hp brushless water pumps and they used a similar vibration damper.
