i have an inverted .60 in one of my birds, it's much easier to start with the left wingtip resting on my foot, and the right tip in my left hand (ala pylon racers i've seen), i put a 4 stroke plug in it, and it idles very low, somtimes it won't quit when i cut the throttle the whole way, just keeps chugiing for a bit, like an old beater car....
never had a flameout since i put in a 4 stroke plug, but i've run out of fuel more than onece
