Fuselage:
The fuselage is a jig built welded 4031 steel tubing assembly. Engine mount tubing and top wing attachment tripods are integrally welded into the fuselage assembly, and have no rigging adjustment. Before covering the structure is etch primed. Ceconite or poly fiber fabric is applied to the fuselage per manufacturers recommendations.
Undercarriage:
The undercarriage consists of two 4031 steel tube "v" members with ball and socket attachments to the fuselage. The axle shaft rides in an oval channel in a steel box at the bottom of both "v" members. Bungee cord is fastened to the steel boxes and over the axle, allowing the axle to move vertically inside the oval, thus providing shock dampening. The undercarriage is braced against side load by two crossed cables, tensioned by turnbuckles.
Empennage:
The empennage is manufactured of 6031 aluminum tubing. The fin is a simple triangle, with the fin spar tube providing a hinge attachment for the rudder.

Cleaning up the shop and one of our two tables with the square inch grid pattern laid out. The tables measure 37 inches by 6 foot.
GM 3.8L engine we are modifying for use in the aircraft. Our engine page is here. Comparison of wheels. Wheel on left is 21 x 1.65" 36/0.14" spoke wheel weighing 10 lbs. each from import motorcycle about 1979. Wheel on right is 21 x 2.15" 17.5 lbs each 40/0.16" spoke from Harley softail or dyna wide glide models 1984-1999, even though the wheel on the right is much heavier, it is also greatly stronger, so this style will be used on our craft. Feb 09,2008: removed spacer,cone, and roller bearings from Harley wheels which dropped the weight of each wheel to 15 3/4 pounds, after adding disc break rotors and bolts the weight per wheel is 19 lbs. each. Common auto parts store replacement seals for the Harley wheels above: Federal Mogul #471705 (double lip full metal body seal), or Federal Mogul #204505 (single lip full metal body), however seals from denniskirk.com were found to be a direct replacement, part number H55-450. The original Harley wheel bearings had a slightly small ID of 1/2 inch, however Federal Mogul bearings part number A-34 are a direct fit for the Harley wheel hubs and have an ID of just over 3/4 inch.
