RE: o,s, 32 max
freak you are correct the two best sport engines are the 35 LX and the 56LX.
The 35 needs the rear bearing changed out often usaully about every 5-6 gallons. The piston did break on me last month. i need to order a new rod, piston and sleeve. i have some carbon 7.4x8.5 props to try on it.
I posted that video a long time ago. I found out later that it was only a downwind pass that day. Before he always average it out for us. i say it was a 170mph plane. I have a new one that is built. It should be a bit faster hoping to break 180 with it on the Jett 35. This one has no external control linkages and i removed the left side engine cheek cowl. It also came in at 2.9-3.0 lbs minus fuel.
