I had the same problem, also with a 17.5 SS, right out of the package and took the esc out with it first time it was run. Unfortunately, the motor had been hanging on the wall for 8 months and warranty had already run out. Stupid me.

Are you having a problem with either one of the motors? If so what is it?

Check to see if the rotor is turning (slipping) on the rotor shaft. This has happened in the past.
Yeah, i had one do that. It wouldnt happen when turning the motor by hand though. Alot more likely to do it when putting a load on it.

Overheating a motor significantly can melt the epoxy adhesive binding the magnet to the shaft. Any user, who has seriously overheated a BL motor (any mfgs' BL motor) should replace the rotor ASAP.

Overheating demagnetizes the rotor's magnetic material. In addition to not running properly, this bad rotor can damage your controller.

We have seen a lot of seriously damaged motors in the last year---enough for us to change our service policies. Improper use of adjustable esc timing can overheat the motor and melt some of the wire insulation: thus shorting out the windings.

125 F is overheating? Can I send my 3 cogger back?
