Longer hover test. After 2:30 minutes I touched the motor to see if it overheated and it literally gave me a 3rd degree burn as expected. It was about to give up. I will need to bump up the power setup with a new motor and ESC, possible new batteries. It will probably take about a week. Hoping to get it ready for the 50th anniversary. The tuning seems to be OK for now, didn’t have to touch that again.
