Falcon 56. Although many will say its not a Sport plane. But When I built mine I made some mods like little Dihedral, Lowered the wing saddle about 3/4 inch, wing mount bolts, more area on the rudder and elevator, Max deflection, and a OS .40. Balance is set reward.
I let a few guys fly it, that are into 3D .60 profile planes, [ better fliers the me ] They really were impressed and could not believe it was a falcon. If you set up any plane right, or whats right for you, you will get the max performance and will say Mine is the best.
Trust me when I say you can tweek a super sportster or a ultra sport, and many others, the wrong way and you will have a crappy plane.
or build it light and right and tweek for max performance and that is what you will have.
