No need to hold your collective breaths any longer....the first flights went just fine. Used just a little more than 1/2 throttle on takeoff, it tracked well with the Troybuilt tailwheel, and took a click of "up" trim and a couple of clicks of left aileron. I think I only completely opened the throttle once or twice in three flights. The 180 is plenty of power. a 120 would probably be fine for most sport flying. It gets small pretty quickly when you point it up at full power with the 180... So far I've only used low rates set at 65% and 50% expo on the ailerons. Still it will roll very quickly... Did one near full power takeoff and the airplane will begin to roll once airborne due to the torque...not a model that you want to pull off early...

Hopped on the first landing a bit but the second was beautiful...this plane is going to be a lot of fun....and there is no doubt that it will do the IMAC routines!!
