I am not using a BEC. It is disabled.

I have a separate battery pack for the receiver.

I've got the plane ready to fly again (just have to re-check the balance) I'm going to have to take it to the airfield again, and see if I can talk someone into flying it. Hopefully get a few minutes a flight time, and a successful landing, so I can take more measurements.

I want to try a short flight, and get temps, and then figure out if things are good/bad/in-between.
