Rotor blasted, ruined sensor board, wire has been desoldered from motor' B-post. Luckily ESC survived, and motor' stator too (no shortcuts b/w phases and body, and no Ohm spikes between phases), so only -84$ instead of 160 or 320 (for whole system).
After 2 mins after 'finish' i had 215F at the motor

, blasted right before finish line after 8min final. Actually i've overheated it (a bit) before, so no complains about this. The only question to Tekin team is: is it possible to make sensor board w/o elements exposed to rotor?
I have done that twice also.
How often do you change bearings in T8?
How many hours between replacement do Tekin rekommend if the temps are ok?
