I cannot have a 22' wing so have been working on a 3 piece wing (paper) design. My design has a 12' center section. By the time you get out 6' from the centerline of the glider, the bending moment has dropped of significantly. The center section would be skinned to resist torsion and drag effects. The outboard wing sections would have the mid 40% section covered with fabric, similar to the original design, with a drag spar. My hope is to incorporate a very light engine (powered parachute type or large RC or two RC engines) strictly to get to altitude. The other advantage of this is that it allows my empty weight to go up to 254 lbs. Hope to generate some discussion with this.
