He is also a plane ownerr of some experience. I asked him about effects of drag, slipping and would streamlinig the exposed wood/tubes help. G'day Steve, Yes, the drag will be increased with an exposed fuselage structure. Will it fly? That depends on the available thrust horsepower available. Enough, and it will fly. The next question is: How does not covering the fuselage affect the stability and control as well as the balance of the aircraft? Unknown. Slipping should work. The exposed fuselage may, or may not, have more drag than the covered fuselage in a slip. Streamlining might help the aerodynamics but may not help the structural strength. If left uncovered, the owner will not just be a test pilot for a known design, but an EXPERIMENTAL test pilot for an "unknown" design.
