hey, guys. I have been designing a manned glider called the G-1a "Adder", it is roughly based on the "Natter", of WWII, but is a GLIDER no rocket power, and with a longer wingspan. the plane will be made out of Foam, but will have a pipe running through the Wings to stiffen them, and a hard shell, like papier mache, or fiberglass. I have a rough sketch here and am open to suggestions on how to make it better. I just want to know if my design will fly.
