I have been having problems trying the get a flatter curve on the throttle on my gas planes. Mechanically, when the servo arm to push-rod angle is 90 degree, the butterfly is half open. The verbiage below was taken off an article on the internet regarding 10X setup. The 50% statement is true for both of my gas planes. At half stick, I am making ~90% power. I have a JR 783 PCM radio and don’t have a curve mix or exponential capability for throttle channel.

What are my options? Digital Throttle servo selection? Alternative throttle linkage geometry?

“Yep.. you read right. Throttle setup is just as important to a smooth flight as anything else. I use the throttle curves (code 18) to make the throttle response as linear as possible. I want to hear an rpm change with every click on the stick. Most gas engines seem to deliver most of the power in the initial 50% of the carb movement.. so this requires a initially flat curve that then steepened sharply. It takes some playing to really get it perfect, but when done it makes it SO much easier to get a smooth, constant speed flight. Those of you without dedicated throttle curves can use a programmable point mixer and mix throttle to throttle to get the same effect.”
