Hey guys I had a couple of thoughts. I noticed that some of the throttle installs are using all metal pushrods and servo's right near the engine. I always thought this was a sure way to induce RF noise into the system. Everything I read says to use non-metallic pushrods. [Hey Roger..now is a good time to plug your fiber-optic servo extensions...just kidding :-)] I have both my choke and throttle servo mounted in the fuse behind the wing tube and used nyrod type pushrods. I did not notice a detent on the choke it seem to work fine with a standard servo. I'm using a hitec 5945 on throttle which seems to provide rock solid throttle control. My concern with using a standard servo on throttle was the holding power since I am not using a return spring on my throttle arm. VinceL the choke can be operated manually with a rod but the servo for me is more convenient.
