Iam building my first gas engine plane. It is a Yak with a 26 CC RCGF engine and I am using 2.4 radio. My question is what material should my pushrod to the throttle be made. Should Iworry about interference? I've heard some say that it is not a problem with 2.4. One guy told me he had the golden rod on his gasser and the heat from the engine softened it and it bent. Your thoughts?
