Oh good - some experts. Here's MY problem:

I removed the OS 61FX from my Hobbistar 60, and replaced it with a Kontronic 480 with a Jazz 55-6-18 BEC. I'm using a 4-cell 14.8 volt 4000 maH Lipo. I took it out to the field today, put the plane in a test stand, and gave it full throttle. The motor screamed for about 5 seconds then shut down. It doesn't take much movement on the throttle for the motor to go full blast. I suspect it shut off because it was sucking too much current(?) Looks like I need to adjust the throttle so that the full-up throttle position gives me the maximum allowable power without going above the current limit.

So I read the BEC instructions. It says:

"5.1.1 Automatic adjustment
The joystick tilts of the remote control are adjusted automatically in the APM every time the drive battery is connected:

1. Connect drive battery.
2. Tilt the joystick once all the way forward to the full-throttle position.
.
.
.
The autoprogramming is complete."

Didn't work.

Any suggestions? Maybe I should give it a much shorter burst on full throttle, instead of leaving it there for 5 seconds.
