RE: GP Waco?
I have flown the kit built fifth scale Waco YMF with a Supertigre .75 with no problem. Hell, I even flew one with a Maloney 125, and we all know how weak they were. The .91 should fly it with no problem. The problem is that we have all gotten to the point where overpowering a model is normal. It looks odd to see a Waco or Cub keeping up with a Jug or Corsair around the circuit. These planes fly on the wing, and not on the prop.
