In my older age now 77 I-am still reluctant in giving advise. Especially at the flying field. Mostly electric now, and just don’t know anything about this electric and new radio technology. I guess that’s the biggest reason I went back to U control. Just too complicated for me. I never realized how much I missed it. Chuck teaseley is a friend and he was a former UC guy in his teens. Had flown RC 72. He came out with a shoe string. UC with a RC engine and was using his radio to control the carb. That’s improvise adapt and adjust!!!!!! Had fun doing tough and goes! AJ.
