In 2012 the aircraft was still available in the form of plans and some materials, offered by US Pacific of Fresno, California.
The Mitchell Wing started off as a foot-launched hang glider with good soaring performance. Mitchell later modified the design into a powered ultralight aircraft with wheeled tricycle landing gear, known as the B-10. The B-10F is a foot-launched variant with only two wheels.[2] The B-10 was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 2540NaN0. The aircraft has a standard empty weight of 2450NaN0.
The B-10's fuselage is made from aluminum tubing while the wing has a birch plywood D-cell leading edge and foam ribs, covered with Dacron sailcloth or doped aircraft fabric. The tailless wing is common to all three variants.[2] It is of tapered and lightly-swept form, employing a NACA 23015 airfoil. It has a span of 361NaN1 span wing, area of 136square feet, aspect ratio of 8:1. The 8.51NaN1 outboard wing panels have 6 degrees of dihedral and the wing overall has 12 degrees of sweep. The controls are conventional three axis, comprising trailing elevons and wing tip mounted vertical rudders, and operated via a top-mounted centre stick.
Power is provided by a single engine in pusher configuration, mounted behind the pilot's seat. Small engines in the 20to range can be used: The prototype was fitted with a 120NaN0 McCulloch MC101, with Chrysler West Bend and McCulloch two-strokes being recommended.[2] [4] and the Zenoah G-25 of 220NaN0 has been fitted.
Construction time for the supplied plans is estimated at 500 hours.
The B-10 can be quickly disassembled for ground transport or storage. The outer wing panels fold or can be removed, the fuselage cage is detachable and the tip rudders are quickly removed.[4]
The B-10 was subsequently developed into the A-10 and two-seat T-10 and the mid-wing Mitchell U-2 Superwing.
