RE: incidence problem
Engine thrust will not change aileron trim significantly.
Before you change the thrust put in 6 clicks of right rudder trim. Re-trim the ailerons for straight and level. Also carefully trim the plane for hands-off stright and level. It should fly most the length of the field straight and level with no roll or pitch changes at roughly 3/4 to 7/8 thottle, depending on your level cruise speed. Now check the up lines. If its still pulling left hard, make sure you fly left to right and pull up, then fly right to left and pull up. If it peels off to its left both times add in some right thrust.
Now also adjust up and down thrust at this time as well.
Next trim for straight down lines with throtle at idle. Put throttle to elevator mix in as appropriate. Use ORIG if you have a 10X or 9303 disable the throttle trim within the mix.
Finally, after all the above is done, fly stright and level and then cut the throttle, carefully watch which way it turns. If it turns to the left, add negative incidence to the left wing. Vice versa if it starts to to roll right as the plane slows down. You can add a bit of elevator in so it does not drop. Kind of like you are going in to a spin entry.
After you adjust incidence, and do all the above, see if the aileron trim is still off. If it is, and the plane flies straight in the above tests, don't worry about the aileron being off.
