Often a funfly has CG pretty far back, and often a funfly has a very short tail moment. With a short tail moment and rear ward CG, a funfly could easily be flow using the ailerons as ailevons. As a fact, many pilots with funflys that has had less than successful encounters with the ground, will shorten the fuse, do away with the horizontal stab and elevators, move CG back a little, and fly it as a flying wing. My Aeron, although not tail heavy, could easily be flow like that, even with the passive elevator still there.
