HI ROTARYPHILE, The tailstander is going to be one of my projects this winter done in a 1/2A size. I want it to resemble something from out of a BUCK ROGERS cartoon. I have never used a gyro for anything yet, but something like this might need 2 sets of hands to fly. I agree that coupled flaperons give the best response, and with my MORRIS SUDOKOI, I just leave them on all the time. One last comment from me about hovering is the 4 strokes have a definite advantage in general in the side by side comparisons that I've seen, and give the pilot more room for error with throttle control.
