Mike,



I would say no. Reason being is that you still have the front prop feeding the rear. Some have experimented with different pitch between the two with the rear prop having more pitch to compensate. The best solution is just go with a biplane. That's what I did when I set out to design my own pattern airplane. There are now 5 of these in existence, the last ARC version I built was setup for a contra. I'm anxiously waiting for it's owner to finish it up and see it in action. For now the single prop versions seem to be doing quite well.
