Default RE: SYSSA 30CC GAS MADE IN USA

I'm not saying the engine will not turn an 18-10 at 7800rpm...It will...
ANY 18 inch prop with a 6 inch pitch, even at 10,000 rpm, makes only 22 lbs thrust...ANY SIX pitch prop....
A Mejzlik 18-6 at 9000 rpm makes a little over 17 lbs measured thrust...
A piped G26 turns 10,000 with the same prop....
I have a DLE30 here, and a tuned pipe...It turns an 18-8 prop at 8300 with the STOCK muffler...I have a Mac's Products tuned pipe, already tested it...forgot to write down the rpm, will do later..
Maybe Todd know the thrust, I'm quite sure he has not seen 26 lbs....
Todd ????
FWIW... I had Todd's engine in my hand at Joe Nall, told him at that time to send me one..If he remembers and has an extra, he will..
