ok so it seems as though my airfoil will work. most the flying i will do is big loops, cuban 8s ect... now according to what inewqban is saying, i will need a little bit of positive incidence on the wing and maybe some negative incidence on the stab. as far as weight, i should have a pretty light wing loading, b/c i am going to use foam ribs with cap strips, and foam formers. should be alot lighter and pretty strong. now, on the tail, should i build it flat like most other kits, or should i use an airfoil shape as well (symmetrical)
