I have recently bought a T100. Unfortunately, with just a few minutes of run time underwater, the thruster stopped rotating. The blades were hard to rotate manually, which made me think that there was something stuck in the rotor.
When I disassembled the motor, I was shocked to find that the stator axis was bent and it was scrapping the inner diameter of the rotor (see attached image). I could not believe how it got bent so easily without much usage.
Can y0u please explain why this may have happened, so that we could avoid this in the future. Also, will there be any possibility of replacement or a repair to make it working again.
