I bought another motor and have 78 flights on it now. Approaching 6 gallons. Running redline now at 40:1.

Have it at the St Clairsville contest this weekend thanks to Mark Hunt getting me the templates to be able to make another canopy after losing my original in the corn field.

Started running the apc 21x10 wpn this week. Turned 6700 when I tached it. That's on a 29" pipe. Planes not super fast but pulls like a mule and doesn't stop. Originally bought this prop to try on my YS 175 which turned it at 6300 the only time I ever tached it.

Bob Kane had a radio shack db meter with him, so we took it out and ran it up and got a reading of 93db over grass. Engine is hard mounted on a balsa, ply, foam airframe. I realize this isn't the most accurate meter in the world but it does offer some encouragement. We have the D4 year end meet at Muncie end of September and we're going to try and get the same sound meter used at the nats and get a good reading. Will try the 20.5x10 also. I did the sound testing for masters at this years nats, so I have a pretty good idea how this will compare to the other setups.

The sound factor has always been in the back of my mind. If it couldn't be used at the nats without penalty, then it wouldn't be overly useful to me as I like to fly there every once in a while. If it's successful, I can't think of any other argument that gas power isn't a realistic alternative for competition. Biggest problem would be finding an airframe.
