    Does anyone know why my motor mount keeps coming loose?

    I just rebuilt my transmission and I hit the gas full speed on 6s and the motor mount came loose and it keeps doing that even with half throttle. Is it my motor or the mount?

    If it's not the screws that hold the mount to the transmission housing, it could be the transmission housing. If you accidentally over tightened those screws and stripped the holes in the housing, they won't likely hold up to 6S power anymore.

    Do all three of those screws have a hard "stop" that you can feel them hit when tightening, or can you just turn them forever? If they don't have that hard "stop" anymore, they're stripped and you'll need a new Xmission housing to secure your motor mount to.

    It’s not the part that mounts to the trans housing. It’s the part that holds on to the motor. (Those two screws) and the make that hard stop when I tighten them.

    I use lock tight. It ended up being the motor mount so I have a new one on there and it hasn’t moved
