IBob,
Thank you for your response.
Yes, I have completed both wings, ailerons, rudder and elevator without relocating any holes. The precise alignment of over 400+ holes is amazing.
It is surprising that such a simple door support requires crude adjustment by grinding an 1/8 inch or so off the aluminum bracket. These end brackets seem very thick for the non-structural application. Seems that a piece of bent sheet metal like the one on the trailing edge of the wing tip would have been adequate, but I have not operated the doors so I will find out then.
