Fred also sold the gear retraction system as an aid to the home-builder. According to Fred two Hurricanes are in museums because of the age of the owners, two are under construction, and two sets of plans have just been sold to enthusiasts in Canada."
Remarks by Fred Sindlinger: "The aircraft is built to 5/8 scale, except for the following: cockpit is 4 in (10.2 cm) out of scale in height and width, elevators are 12 percent over-scale. The aircraft is all wood except for the engine mount.
Wing spars are a laminated 'I' beam section of 3/4 in (19 mm) spruce and plywood. The entire wing is skinned with 3/32 in (2.4 mm) plywood and fabric covered. Flaps are skinned with 1/16 in (1.6 mm) plywood and fabric covered. Stabilizer and fin are built like the wings with the elevator and rudder made from 1/4 in (6.4 mm) spruce and fabric covered.
The fuselage from firewall to aft of cockpit is a monocoque structure with a wood truss from cockpit to tail. Stringers and fabric give the appearance of the actual Hurricane. The landing gear was welded from standard sizes of 4130 aircraft tubing with coil springs for shock absorption. The gear retracts manually with a hand crank on the sidewall of the cockpit. The tail wheel is fixed. The glass fiber engine cowling was laid up over a plaster mold."
