RE: Cox Reed Valve FAQ
aeomaster32:
If I may ask, whose Playboy are you using? I use the Reynolds Playboy which also wieghs 17 1/2 oz. I fly it at 5-5100 RPM.
In the old days with the 8cc tank I used to get 7 1/2 - 7 3/4 minute engine runs. I used to spin it down to lower altitude twice before the final climb. Good stuff...
