BK or Radio problem?

[hoober]

The old motor is ok, it's the new lower kv smaller motor that has the rotor spinning. It's brand new, but I've had it for many months. I may take it apart cuz I have no idea how rotors are put together. The outside of it spins smoothly , but it is not spinning the shaft unless it's on a stand on the bench.

I think my problem is radio interferance, but it only shows up as the power level increases. I suspect I can run a small motor geared low on a 6S and have no trouble. I will find another low kv small motor if I have one.
