Is there anyone else who has tuned your heli engine while running it. I have read something about tunning it while it is running but have it strapped down and up high so you can adjust both valves and wile strapped down test it out at full throttle. So set the idle speed until it idles smoothly, then set the high end valve so that it gets full throttle power. Someone tell me if this sounds good. I got an idea from someone here and also from the Ray's helicopter book. Let me know your thoughts.
