I have to admit that the DA I currently have is in California. But the DA I had out here (actually 6800 feet) was turning at 7,000-7100 on a 22X8. Glad everything is working out for you. It looks like this plane isn't so bad for a 45-50cc gasser if it can be built to 13.5 pounds like you stated. I am interested in seeing how the H9 Cap compares - they're talking about 15+ pounds, which would be pretty depressing[&o]
