Question I haven't calculated the precise wing loading but its more than low enough for this airplane.I haven't taken them for their maiden flight yet, I will have to update this later. I will close by pointing out that two bicycle mechanics figured out how to fly well by understanding aerodynamics were king while simultaneously beating out a huge government funded push to create a controllable airplane headed up by a man with the familiar name Langley who insisted horsepower was what was needed. Sign up for our newsletter and be in the know. The epoxy boards would ding and dent to hell and back if you just looked at them.

Hes using foam insulation sheets for the body of the fuselage, reinforced with plywood and poplar struts. his birdsshort lived bcs they will fall apart within 2 yrs or simply become a hazzard when binding surfaces and joints weaken in no timebut who cares The wood rib has the primary compression and tension members in the capstrip, with the diagonals absorbing shear loads, converted to compression and tension loads along the legs of the truss. It has the advantage of being very easy to sand and shape, cuts easily with a hot wire, and, in the lower densities ("white" and "blue") is fairly light. You can use Value XPS to fold airfoil shapes by adding a layer of tape to support the leading edge curve during bending. When they were correct, we used our vellum patterns to transfer the patterns onto the actual fuselage plug. Wings are hung to the fuselage with a single strut. 3-6 coats should do it.
