Today I fixed the mistake I made on the struts. Here are the steps to correct the issue I created. 1. Level aircraft 2. run string from one wingtip to the other. 3. set wing height to 85mm =/-5mm at inboard rib. 4. Mount struts lose to get correct length. 5. mark holes for weldment and strut. 5. drill holes and then remount. 6. check dihedral (1.3 deg. on both wings) 7. repeat on other wing.
