Mitchell Wing



A hang‑gliding fanatic, Dr H Long, gave Don Mitchell control of a high performance wing. It has aerodynamic control of external “stabilator” surfaces about all three axises through the use of a joystick. No weight shift is required. Spoilers are used to initiate a turn or to steepen the glide path for landing. Its extremely flat glide and low sink rate allow it to takeoff and land in almost ‘no wind’ conditions.
The wing is an all-wood structure with foam leading edge ribs. It has a single built-up C-spar with aircraft birch plywood torsion proof leading edge. The built-up truss ribs aft of the spar ar covered with seconite fabric.
The 8 ft 6 in outboard wing panels fold up over on top of the centre section for transportation. They may be removed as three pins connect outboard panels to the centre section.
The pilot is housed in a metal cage below the wing. Spoiler control is on the left, the control stick on the right. In flight the pilot goes into the supine position. A large clear mylar covering on the traiing edge above the pilot gives visibility overhead. The pilots cage folds up for ease in transportation.




By 1975 this same wing had become the B‑10. The first powered version now carries the designation of B40F (F for foot launch).


The Mitchell was a rigid hang glider in wood, sold in plans. Two American companies were selling the rigid Mitchell. U.S Pacific sells plans and wood kits while Ameriplanes sells aluminium kits.
The 1976 wing was for advanced pilots. At lrast 20 service bulletins were to be applied to be safe.
Very pleasant in flight despite the strong reverse yaw but stable.The first 2 minutes are crucial because you have to understand everything quickly, the reverse yaw, the use of the rudders and the sensitivity of the handle on the pitch.
