That is very interesting. I will try that. I did not think about adjusting at full throttle. I know one thing different that I tried today was adjusting the low end valve while the copter is runny. And I heard the engine go from a bad idle to a stronger one. There are so many different things I can try. I was reading a part of this book that was recamended for me to get which is Rays Authoritative Helicopter Manual, where he builds some kind of stand out of a ladder so he can do adjustments while the blades are even spinning as you said. I should lock it down and try different mixtures and adjustments. That way I can see how much power I am really getting. Thanks BLS! Thanks everyone too. I am not leaving anyone out. You guys have all helped greatly!
