Feigo 380 10s ?

[Andris Golts]

Hi all i have a Feigo 380 10s 3940kv bl motor installed in a 19'' mono on 2s power applied a bit off throttle to ckeck everything when i noticed a large wobble in the motor output shaft i have not removed the motor or dropped it or have hit anything with the boat im beside myself over this issue. What may cause the motor output shaft to bend and not turn true? Regards Andris Golts.

Is the wobble with coupler on or off? Couplers can be bad or go bad over time. It also uses a 1/8" shaft, not easy to bend but, not impossible. You are usually very meticulous in your building so, I'd be very surprised if you built something incorrectly causing this.
