RE: Sebart Wind 110
sorry this thing is giving you a headache. I find it odd the motor has failed electricly from its own doing. I havent been keeping up with castles run of bad luck but I would be suspicious of the esc being the root cause. granted my a50 in my heli is 6 yo but it runs 200 deg and has for 100s of flights so I think the adhesives they use (or did) are very tolerant of high temps. when you took your 6500rpm reading what was the volts and amps? any chance the electrical smell is coming from the esc?
