My Align 400L 2500KV just died yesterday. I think it was because of overheating! Been outside flying 1/2 a pack with out problems. Then inside to make some adjustments and hovering.
Did some fast collective inputs to see climb rate and then suddenly in hover, the bird autoed down. Tried rotating up again but the motor behaved strange. (Could go both directions without power!).
Took the motor out and I can feel there is not much torque in the magnets. The coils seems ok.
I was running the motor without the heatsink. Maybe a bad idea.
Been trying to find topics about Align 400L/S motors dying but I can only find examples of Align motors which comes apart.
Has anybody had the same problem?
