RE: airwild extra 260 29% who's got one?
I didn't need to put in anymore right thrust than what already built in and the airplane hovered great, just 2-3 clicks of right ruder trim with fine trim rate(2 out of 4-coarse). I had a DA 50 with the bisson wraparound muffler. My ignition battery is on the wingtube with my receiver and the receiver battery was at the end of the servo tray (rudder). Ignition box is on the engine box. I also replaced the tail gear with the carbon fiber gear. With this setup, the CG was almost perfect. I could have move the CG aft a little bit more.
Check your CG. Mine came out almost 15lbs. I used nmh batteries - 4 cells on ign, 5 cells on recv. Normal alum. spinner with a couples of holes drilled out to lightened it up a bit.
