Futaba 3PM FM with HRS not working with 2 controllers

[ncalenda]

at this point, I have to throw out the motor, it doesn't work. I do have another in it now, that works fine. I put the heatsink on top, and have a masive fan, and will consider new bearings all around.

I have not opened up the motor, but when I spin the shaft, it will spin freely as if nothing is inside.
