Andrew,

ER is right on the money. I have owned and flown BVM D/F jets from the early Sport Sharks through Aggressor III and Ultra Vipers. By the time I got the first Ultra Viper, I knew of the benefits of separate flaps and ailerons because my flying buddy Vernon had the flaperon setup on his first Viper. He never liked the way it handled in the landing pattern with the flaperons. It just wasn't as stable and predicatble as the Aggressors with separate flaps. When I built my first Ultra Viper, I installed separate flaps and ailerons on it. It made a huge difference in the handling of the aircraft. The Ultra Viper becomes a rock solid flyer at any airspeed all the way to touch down when using separate surfaces. The flap/aileron length is 20 inches on the Ultra Viper. It is split 50/50. That arrangement has worked very well for me on two Ultra Vipers. I set it up this way because BVM split the F/A 50/50 on the Agg. III. I just went and measured the Bandit. It measures F/A total length 24.5 inches with the aileron 11 inches. BV knows how to design great flying jets, so this should be a pretty good setup.

Hope this helps.
