RE: Roll axis trim changes with airspeed change.
I am focused on the wing becasue I have checked the tail group and it all appears to be properly lined up and straight. The amount of aileron trim required to fly straight seems to indicate something wing related. Im suspecting there may be more than one problem. I know that there is a small area on the right wing that is very slightly raised and therefore thicker than the left wing. I dont think this is the entire problem however. I have not checked the hinge line skin for delamination and flexing. I dont think this is it but it could be. I plan to try to check wing incidence one wing compared to the other. I hope this isnt off because it will be hard to correct, but I wouldnt be suprised if there is an incidenc issue one wing compared to the other. I plan to check this later today. I am currently re doing the aileron linkage so I can use a shorter servo arm. Im quite sure that this wont be a the solution to all my issues however. At some point if need be I will get some servos with better resolution but I dont think that this is the total solution either. I need to find a good way to check lateral balance as well. Its kind of a hard to do with a 35 lb airplane. I did a crude check of this and it appears that if anything the left wing is the heavy side which would only help my sistuation not hurt it.
Thanks for all the ideas, keep them coming Im learning a lot.
