RE: Show your overpowered plane...
I have an Ohio RC Extra 300 (88"W/S, 20 pounds) with a ZDZ 80. The plane accelerates nicely going vertical, most other flying is at 1/4 throttle.
I also have a Dave Patrick Edge 540 with a ZDZ 50 which is definatlely a vertical rocket at 15 pounds but not quite as over powered as the Ohio RC Extra.
