Rotor spun on shaft
Yesterday i managed to spin the rotor on it's shaft. During a 20 min race with my offshore endurance boat, the tow rope came loose (we have to have one), and wound up in the prop. The flex shaft held up but the shaft spun in the rotor. The motor is a TP 4060 580kv running on 10s. My thought was to swap out the rotor from another 4060 TP motor, however while the length is the same, the od of the rotor is bigger so that is a no go. It may be a little tricky to find another motor this size and kv, neither OSE or RCBB (where it came from) have anything low enough in kv.
So for the mean time, and for club day next Sunday, I am going to try fixing the shaft back into the rotor with bearing retainer. The motor runs end bell temps of <50*C so heat should not be too much of an issue, I will see if I can get some high temp resistance stuff.
Does anyone know any other way, or even how I might find another low kv motor?
Appreciate any advice, other than that it will be give it a crack and see what happens!
