Your engine may have a screw that can hold the carb open. My OS-35FP that I have on a cardinal has an RC engine installed, I simply tightened up screw on the carb which locked the carb in the full open position. This eliminated the need to put a wire to keep the carb open.
You can also fly with throttle on CL, except for one model all of my models have throttle control
Fred, do use a 3-line control for throttle control?
Has a system ever been tried that couples the throttle to the elevator? I was thinking like a faired elev at part throttle and full deflection, up or down, giving full throttle?
