The Mark III Xtra has become Kolbs most popular aircraft. A six foot chord and a 30 foot span provides for lift at 24 mph (14 with flaps down) and low drag co-efficient at the maximum level flight speed of 64 MPH. I would rather not change a design that seems to work well but I could use some help in designing a spar or spar system that will support the wing/aircraft combintion. The improved version incorporated a higher seat to prevent the pilot's feet from dragging on the ground. Human powered aircraft need to have a low wing loading so very little energy is needed to sustain flight. If you just want to make one part, and don't care about repeatability, you may choose the "lost mold" method. After the blanks are made, the wing templates can be aligned on them and the airfoil can be cut. My current idea is to use a Polystyrene foam core ( 6" x 2" cross section) and laminate it with 1 layer of 12k carbon fiber, and vacuum infuse epoxy resin. The "negatives" can be used to store the completed wing perfectly. The landing gear consists of a one piece prefab aluminum slab made from 1/2 x 4 2024-T351 alloy. Complete airframe kit cost: $6,995.
