Hi Rush

Lately we have had 3 K80's doing the same thing. All quiting at around 60 000 rpm. Hi ambient around 30 deg C and fairly high humidity and 5000ft ABSL.

We have not solved the problem. We sent the motor to a KingTech rep here who tested it at 900 ft ABSL without problems. We tried all settings on the ECU without any issues. Motors ran fine during the winter. Have sent the one back to KingTech and will see what they say?
