Stan,
 
Adjust the rigging so that the deployment angles are as close as possible.  You will find that further adjustment may be necessary while you are in the test flying phase of the airworthiness certification.  I.E. A wing may seem inordinately "heavy" and adjusting the flap rigging may correct that condition (one side up a half turn on the bearing and the other down a half turn).

I’m building in my garage so I usually work one side of the plane then the other. So far that has worked well. 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?
