So we had a plane we built from a guide online, used it at regionals, and it worked to win us a medal. Our plane design was the from the guide many people have found online by googling "wright stuff". But we are now looking to go on a more custom route to improve our plane. Our first plan is make cambered wings (Which if anyone has a guide or advice on dimensions of cambered wings, I would appreciate if you shared it). The second thing we noticed is our tail seemed to be kind of small. Maybe it was a problem with it's angle, but I think it wasn't getting enough lift.
So my main question is why not just make a tail that is the max size? Isn't more lift better? Wont that move my center of gravity closer to the center, but also allow me to carry more weight? At the last competition one of the judges said my tail should be 18% the surface area of my main wing, which seemed way to small.
I guess another way to ask this question is what problems would there be with a plane like the "Boomerang Plane" http://www.oldwoodtoys.com/other_gliders.htm
I've never seen one before, so there must be something unfavorable about it.
