I posted this in another forum and got no reply. I have a h9 super stick modified with larger ailerons , removed the round vertical stab and replaced it with a ultra stick type vertical stab & rudder with 3" split elevators. The 3d guys in my club can do just about anything with it. knife edge is work but it'll do it. I was wondering if you could take a stick kit or arf and, using seperate wing halves , run a wing tube through the fuse to put the wings directly in the line of thrust. you could then place a cockpit & canopy on the wing saddle area. If built light this would be a fun and inexpensive aerobatic plane. I would try but I don't feel I have the building knowledge to make sure the wing is strong enough.
