I want to solicit some advice... I bought a GN-1 with a C-85-12 back in Sept. It is swinging a metal McCauley 74x41prop which was on original A65 (all my W&B data, etc. based on A65 with thisprop).I flew a lot this past weekend. I climb with gusto, but burn a lot of fuel at cruise.I can spin up to 2500 and do 80 knots. Does that sound right? BTW, my wing is clipped Cub, so, should get a little more speed, maybe? Should I re-pitch metal? Try a good wood prop? I worry about W&B if I get woodprop.I boought a Piet, so speed not the goal. Fuel burn my aim....decrease it.Thanks, Scott L. for previous reply. You have similar craft, so value your input.-ZekeSent from my iPad________________________________________________________________________________Subject: Pietenpol-List: Simplicity wins... again...

Marcus, I've got a GN-1 with an A-75 in it. It's got a metal McCauley 74x39 on it. WOTis 2500rpm at around 85mph indicated. Climb is pretty good. I typically cruiseat about 2250 rpm, burn at that rate is around 4.5 - 5 gallon per hour, speedaround 75mph. Your cruise of 80 kts (92mph) seams a little fast to me - but I guess it is possible.I'm not really comfortable in my plane at 90+mph though, it buffets mearound too much.Lorin--------Lorin MillerWaiex N81YXGN-1 N30PPRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 29 Apr 2013 21:03:34 -0600Subject: Re: Pietenpol-List: Simplicity wins... again...
