Successful test flight today. It seems to fly pretty well, at least as well as my excelleron 50. With my 55AX at around 5500 feet the power to weight level could have been better, as garcfield said its a pretty high wing loading. I need to try some higher nitro fuel and maybe drop from a 13x6 prop to a 13x5, I think I was under 11000 rpm on the 13x6. I might also improve the weight by dropping the tank size the stock is 12 oz after a 10 min flight time I still had half a tank.
I had the misfortune of seeing a $8000 competition pattern plane flying in between my flights, so my expectations might be a little off.
