I had a Sterba 54 X 52 That got me around 3,350 IIRC. It seemed t0 be just about right for the 2180. It would idle around 850 static and would show about 950 at idle on final. I can tell you from experience that the extra 150 RPM will make it glide forever.

I do not understand why I am getting the speed I am getting at low rpm's. This is a 2180 VW engine (Great Planes) with a Ellison TB carb. I am pulling a Sterba 54 x 54 prop and the top rpms that I can achieve is around 3150. I may have too much prop.My craft is very clean, very little drag. Down the runway this past Friday on a low pass, rpm 2700, slight decent and an airspeed of 185 mph. At 2924 rpm indicated cruise shows 150 mph. This is high according to other KR's. Next week I will go back and re-check all of these stats using a gps. I have already done it once. ----- Original Message ----- From: "Jim Faughn" <jfau...@socket.net> To: "'Jim Handzus'" <canh...@qwest.net>; "'KRnet'" <kr...@mylist.net> Sent: Saturday, April 29, 2006 4:48 PM Subject: RE: KR> 5th flight of 880AB > Bill, > > I am reading in the message below that "at 100 mph and 1100 rpm this KR > will > not descend."
