Im planning to use the cf for the main spar and a second spar at 50% chord, wing skins and ailerons and flaps and landing gear.
But im going to build a stock kr2 for now. I was trying to copy the colomban mc 100. high wing loading (about same as a cessna!). small wetted surface area and light weight. the gear needs to be taller to accommodate the flaps. which is composed of a fowler flap under a plain flap, and it needs to be very torsionally rigid so i can actuate it reliably from the fuselage. And the wing root needs to be 5.4 inches thick using a different 15 % airfoil.
