RE: OS 61 Hanno Special question
Flew today and had great results. The 12/11 prop and 25% nitro gave me a consistant 11,200 rpm's. I would like to get the RPM's down a bit though since the overall opinion is run about 9500 rpm's, so I wil be trying other props. This is a 40-size a/c, so prop clearance is an issue if I go to 13 inch props. Does anyone know if they make props where pitch is greater than length? i.e. 12/13 or 12/14
Thanks for all the help. BTW I think I was hitting about 130+ mph! WOO HOO !!!
