HPVT49 RPM ADVICE PLEASE

Postby boz » Thu Sep 09, 2010 11:05 am

I have a new Austrian HPVT49 which I ran today for the first time. The book that came with it says rev range from 500-15000 rpm, but I only managed 8000 rpm running a bit on the rich side, with a 12x6 prop. I really dont see it getting anywhere near 15000 rpm when fully run in. What do you guys think I could realistically expect on a 12x6 ? Thanks.

8000 is about right for a 12x6. To get 15,000 you would need a much smaller prop.
