I dissagree strongly with DBCherry's comments on needing oposite aileron in a turn. All of mine (3 quarter scale) benefited greatly from coordinated turns--i.e. right rudder with right aileron for a right turn else severe skidding occured. Now, if you want a flat turn (no bank but change of heading) then you do have to turn with the rudder and used opposite aileron to hold the planes wings level with the horizon; looks unnatural but works. One other comment, after you get it trimmed out, you may find you can benefit by making minor changes in downthrust. All of mine require about 5 degrees downthrust to prevent zooming with sudden power increases.
