I used one of the first EAA, AB-DAR'sRonald Morton from Sequin, Texas.He flew in with his wife in their homebuild BD-4.He spend two hours doing a thorough inspection of my Pietenpol.His wife did all the FAA paper work.They never looked at the receipts or the log book, just had to sign andocument that confirms the 51% rule.Cost $ 100,-- for travel expenses.Absolute first class.For my repairman certificate I was also lucky, the FAA guy at the localFSDO at Ellington was an EAA member.No appointment, just walked in with all my documentation, half an hourlater doneSo simple a cavemen can do it :-)Hans.________________________________________________________________________________Subject: RE: Pietenpol-List: Several ?? on this Pietenpol I just bought.Date: Thu, 8 Feb 2007 12:06:48 -0500

Subject: Re: Pietenpol-List: Several ?? on this Pietenpol I just bought.I'm no expert, but recall reading something about this before. It has to do with the ability of the VW to turn a big prop fast enough. Basically the VW doesn't have the power to get to 3400RPM, unless you use a fairly small prop.This in turn doesn't give you the Thrust from the prop that is needed for thePietenpol. On a slicker airframe, like a KR2, you can use the smaller prop, and turn the 3400 RPM, and it all works out nicely. ________________________________________________________________________________

OK??Help me understand this, I have a Hapi VW conversion weighting in at 165lbs,it's rated at 65hp at takeoff 3600 rpm with a continues 60hp rating at 3400,if the motor is running the way it should 60 65 hp should be enough power for the Pietenpol and 2 pilots. Right?Of course the weight and balance needs to be correct. I don't see the problem. Can someone help me with this??ThanksLike Boyce said in the last post, the VW engine just isn't right for the Pietenpol. A draggy airframe like the Piet requires a lot of Torque from it'sengine, and a large diameter prop. The Model A engine, with it's long stroke,makes a lot of torque at low RPM, but it's lucky to make 35 or 40 horsepower. Bottom line is that a V W engine, with it's short stroke, will NOT work on a Pietenpol.Chuck G.NX770CG________________________________________________________________________________Date: Thu, 8 Feb 2007 14:53:10 -0800 (PST)

Subject: Re: Pietenpol-List: Several ?? on this Pietenpol I just bought.If the VW could turn the prop 3600RPM, the blades would be going too fast, supersonic even?? Scary to say that in the same sentence as VW OR Pietenpol! Most props are pitch for max efficiency at about 2600-2800RPM (from what I'veread). If the VW engine turned the prop at that RPM, it would make no where near 60hp. Now, maybe you could hook it all to a PSRU, rev the engine to 3600,slow the prop, then maybe you can get it to work. But why? By the time you figure it all out, tune it, make a mount, figure the weight and balance...it'sno better than a common old A-65. And, you'll probably have more money in it in the long run.
