From: helspersew@aol.com Hi Larry, If I'm not mistaken Bernard referenced 1650 as a cruise RPM in the F&G. My home-made prop is a 76/46. Seems to work fine. Dan Helsper Puryear, TN -----Original Message----- From: Lawrence Williams Sent: Sat, Apr 16, 2011 8:19 pm Subject: Pietenpol-List: Elite Pietenpol purists only! What do you other model "A" guys use for a cruise RPM? I could have sworn t hat Mr. Pietenpol used 1850 but I can't remember where I got that number. ( Not that I'm getting forgetful but in my line of work some things get a lit tle fuzzy if I don't use them often.) Also, I'm polling the faithful for prop sizes. I'm running a 74x48 but agai n, I seem to remember that Mr. Pietenpol had a range that he recommended th at had a lot less pitch.....I think, maybe, possibly.....or maybe not. Chet Peek's book has some references but I can't find my copy right now and I'm not too sure where he got his info. I believe it differed from what I had heard. Thanks for your help!

Douwe ________________________________ Message 3 _____________________________________ Time: 06:12:01 AM PST US Subject: Re: Pietenpol-List: Elite Pietenpol purists only! From: Ryan Mueller Per the Bible...: "The airplanes that we build for the Ford engine (i.e. Air Camper/Sky Scout) weigh approximately 620 pounds empty. They carry two 170 pound people with the engine throttle less than half open. We recommend the engine to turn over at 1750 RPM on the ground and cruise at 1650 RPM in the air, although they will turn up to 1900 RPM in the air at full throttle. However, cruising at 1650 RPM reduces the amount of maintenance that is required for the engine." On props; he talks about the important factors for a prop, and how they tried many different ones before arriving at one that provided the best results, then this: First of all, the propeller must be of good design, good materials and efficient. The diameter should range from 6' 2" to 6' 6" and have a pitch of 4' 0" to 4' 3". The propeller should turn from 1650 RPM on the ground to 1750 RPM with the 4' 0" pitch." Chet's book echoes these comments. He does also include an anecdotal paragraph about a drawing Orrin Hoopman made of a recommended prop in 1933. It was referencing a "stock" prop made for Bernard by Ole Fahlin. The drawings indicated a 44'" pitch, but later measurements showed it was not constant. He concluded that the effective pitch was "too much Bite for the Model A".... If any of you do not own Chet's book yet, you are wrong. Buy a copy! http://www.threepeakspub.com/ If you don't have the F&G Manuals yet I would recommend just getting the "Builder's Manual" from the family. Support them, it contains the text and pics concerning the Pietenpols from the F&G Manuals, and it also has notes, tips and tricks, etc that you won't find anywhere else: http://www.pressenter.com/~apietenp/ Ryan On Sun, Apr 17, 2011 at 5:54 AM, wrote: > Hi Larry, > > If I'm not mistaken Bernard referenced 1650 as a cruise RPM in the F&G.

That's one of the big reasons I even considered buying the Hatz - their annual reunion is at the same time at Brodhead. However, I have been informed that I'll have to park it away from the Piets. Talk about separation of the classes, eh?? ;-) Another reason is that my dad knew Johnny Hatz and I've visited his farm way back when I was a kid. I just stood in awe of one the biplanes he was restoring, an OX-5 powered Waco 10 or Bird if I recall correctly. I've been smitten by the biplane bug ever since.
