Not sure how you peeps are getting even close to 100 mph with this plane...I have one and so does another member of my club
On mine i have an Os 55ax 11x6 prop stock muffler a little over 11k rpm's, clocked at 54 mph
The other one has the same motor turning a 10x6 prop an ultra thrust muffler, rpm's 13.5k clocked at 65 mph
You're way low on RPM's. I have the same engine, stock muffler with an APC 11x7p and I'm getting 14,000 on the ground with 15%. My engine is still breaking in so it's even a little on the rich side. By the way, how'd you manage to have an AUW of 6.2 lbs.? Thats about a full pound lighter than everyone else who's posted including my own.
