Referencing the L21 13 rib wing diagram the aileron hangers are three each 10703. The two flap hangers are 10703-3 (inboard) and 10703-4 (outboard). The blueprint for those refers you to 10912-6 aileron hinge bracket assy for all ten pieces. The -6 designation indicates the base line dimension at 12 15/32 or "L" with a "rise dimension of 3 1/16 to the mounting hole. Those dimensions set the lengths and angle of the bracket to all being the same. As far as I can tell the hanger holes in the rear spar are all drilled at 2 5/16 above the bottom of the spar (actually the last aileron hanger is 1/32 difference but whatever. So my problem is with the hangers all having the same identical mounting hole to pivot hole dimension and mounting angle, the spar having the same height holes but the aileron and flap hinges have different heights themselves? I think the flap bottoms would be higher 7/8" or so than the aileron bottoms and I know that's not right. I am aware they use different false spar clamps and probably come through the false spar at different levels but that would put pressure on the spar web based with the fixed angle built into the 10912-7 bracket assy, not good for the spar! Can any of you straighten me out on this? Or does anyone have a set of wing hangers for flaps/ailerons they can compare the lengths of and are the bracket attach angles actually the same? The way it looks to me the bottom of the flaps would sit 7/8" higher than the ailerons all things equal? I've been going round and round all afternoon on this so thought I would ask for help before building the hangers. I think the flap and aileron hangers should first be different lengths and second the mounting bracket should have different angles built into them. Any one understand what I am saying and have any enlightenment for me?? Again this isn't about the "clamps"(12056, 12056-2 and 10931). I am aware the false spare shapes are different. Thank you in advance...
