On my Lancair #299, I had to rebuild the flap bracket attach points on the inboard ends of the flaps (floxed in the holes, re-drilled at a better angle) to get the inboard and outboard bracket attach angles to match. I gather this is fairly common.
1.8 degree difference may produce noticeable roll asymmetry but should be very controllable and by the way, if you're really concerned, you can just lower the flaps a bit at a time. Yaw asymmetry probably won't even be noticeable.

However, I installed my left Flap and adjusted the control rod to produce a 0-40 degree movement. I hooked it to the Flap actuator to produce these limits and everything was perfect. Now I have attached the right Flap and adjusted the control rod to align with the aileron Unfortunately the Flap actuator produces a 41.8 degree movement. I can’t see how to change this without customizing the Flap installation in some way. So, how much difference will 1.8 degree difference make in flight characteristics at full deployment. Has anyone experienced this and what did you do? Stan Fields L2K #201
