I have had a heavy left wing since flight one. This is corrected with a wedge under the right aileron. The question is whether the heavy wing can be corrected by adjusting the length of either of the W1018 bellcrank to aileron pushrods, thus alleviating the need for the wedge. On the ground, both ailerons line up perfectly with the flap 0 degree position but the outboard end of the left aileron is slightly (1/4 inch) below the trailing edge of the wingtip. I suspect the root of the problem is the left wingtip trailing edge too high but that is not readily correctible at this point. Thanks for any advice; this may be a case of the enemy of good being better as the plane is flying just fine with the wedge.
