Will This Plane Fly?
GW3D = Gary Wright?
Interesting idea James, i've found that taking an idea to an extreme is a very usefull "thought tool". What i mean is, often, why I'm trying to figure out how some small change might affect something, if i think of a very large change, it's easier to figure out. Not sure I explained myself very well, but it's a technique i use quite often to much success (on many things other than airplane design).
Anyway, i can't make a post without making a prediction right? Well, i'll say it will fly, though i'm really not sure about that one. The airfoil is nearly a circle, lol. If it does fly, i would imagine VERY gentle stalls and low speed flight.
41" is a very small span for a plane that size and weight but i guess any more would be too much drag... given some airspeed it should produce tons of lift though, so it may not be a problem.
