I have a .40 engine that starts easy, idles fine, and runs well at full throtle. Problem is, full throtle on the engine is only about 90% throtle on the radio. When I push full throtle on the radio, which I might accidently do while the plane is in the air, the engine dies. It's as if the carburator goes past full open. What do I need to adjust? Help would be appreciated.

Reduce your control throw on the servo arm. Moving in toward the center of the arm reduces on the throw. You should also see if your linkage to the throttle arm is on the outside hole. This will also help with the overdrive issue you are experiencing. Also you may have EPA or end point adjustment on your radio. This is very helpful.

Thank you ZB.

Randy,

You can do as Zahid wrote.

But if you have a computer radio, you can also tailor the throttle curve, its center point (sub-trim) and its end points (ATV), using the programing in your transmitter.
