a flap that starts at the fuselage and extends outboard of the stub wing. This creates the potential for some very effective flaps.
+++++++++++++++++ One of the primary idea's behind the bent spar is to move the WAF's OUTWARDS. The centre section is then one-piece (canting up for the dihedral where it exits the fuselage) and stretched to about mid span. Then you have ample room for flaps on the centre section (and ailerons on the outboard section). QED. The rear spar is the snag - you are correct is assuming that it sweeps at the WAF intersection. On my dwgs the rear spar now sweeps from the centre line of the aircraft with a constant sweep (and dihedral) to the tip. It will mount to the fuse much the same way the GP4 rear spar mounts. For the information of our intrepid watchdog (with the short bio) - I am not crazy and I have no death wish. Everything that I do from the main spar to the elevator hinges will be checked by someone who knows exactly what he is doing. Steve J
