Help with a Plettenberg please!

[ilpufxit]

I just bought a (slightly) used Plettenburg BigMaxximum motor.

I'm running it with a MM controller, 3s 5000mah lipo in a 8ight buggy. I've been running the same setup with a Feigao8xl with great results.

The problem is the Plet cogs badly on startup. Even when rolling, it won't take throttle. The motor, wires, esc, battery leads and battery all get warm to hot really quickly with a few tries.

When I bought it, I noticed the cogging but I blamed the esc the guy was running because it smelled burnt. I brought it home and swapped in my MM esc, same cogging and instant heat-up. Anyway, I bought it so now its mine and I have to see about fixing it.

I read a bit already and I saw a couple guys mention that they could not turn the bare shaft (of the motor:)with their fingers, too much magnetic resistance. My fingers are pretty normal and to me, it feels like turning a low turn brushed motor, feels notchy but not hard to spin.

Is there anything to do before I send it to Germany or should I just call UPS?
