What a great flying plane!!! flew a half gallon through it today, engine is a little choppy, seems really hard to tune, (this is my first four stroke) transition is poor and it seems to misfire unless run wide open. Guess I will be doing some serious research, its supposed to rain for the next 4 days so I guess that will give me something to do. Fun day By the way with a 14x6 prop that things pulls like a tractor on vertical climbs! Imagine if I had it running right![>:]
