I recently assembled an Aeroworks Extra 260 50cc and put a DLE 55 in it. The plane has about eight flights on it and the engine has about one and a half gallons of gas through it.

When I first did the throttle servo setup, I adjusted my throttle stick on the transmitter to be completely down when the carburetor is closed. The throttle stick is all the way up when the carburetor is completely open.

I noticed that when I'm flying, the plane seems to reach full throttle when my stick is only half way up. That means that very small movements of my stick at around a quarter throttle really affects how much the engine revs up or down. This makes it difficult for throttle control, especially when hovering. That also means I can move my stick around three-fourths throttle and it makes no difference on the engine since it's already at full throttle.

Anyone have any ideas or comments? I'm hoping that when my stick is completely up the engine finally reaches full throttle. Thanks in advance.
