Just flew mine today for the first time. I have a 1500 mah NiMH battery pack under the fuel tank. I have a Higley Aluminum nut and a Dubro aluminum spinner nut running a 16 X 4 wide APC prop. The prop was thin and I had to use a washer so it would tighten down on the shaft. I have 9202 servo's on the elevator and ailerons and a Hitec 615 Metal Gear servo on the rudder, and a standard servo on the throttle. I upgraded all control surfaces to 4 40 rods and used Dubro Quick Links, the ones that are black with the gold pin retainer. Balanced right at 5 inches from leading edge with no weight needed. First flight all that was needed was 2 clicks or right aileron for level flight. Inverted flight required just a trace of down elevator. Recommended control throws are I feel just right. I am using a Futaba 8U Super radio and on high rates have -70 dialed in for expo. Plane is a pure joy to fly and flew it 4 times today. Engine is still new and requires more break in before leaning it out some more. Even rich it pulls out of a hover with authority, however I wouldn't call it excessively over powered, in fact it feels just right to me, but I also use good throttle management. I did try a fast pass and experienced no flutter of any kind. Flight times are very good around 10 minutes with plenty of fuel left for go around. I really like the way it lands. I can land so slow that there is no roll out with good control through out the landing. The controls are very effective at slow speeds even on low rates. For the hovering maneuvers I use high rates. Need more practice though as I haven't done any 3D stuff was into pattern and scale aerobatics but this 3D stuff looks like a blast. I definitely recommend this plane. It is a true winner. Hope this information helps. Happy flying. Chuck
