Mike, thanks for the input. However, I am still interested in the posibility ofbuilding a Piet with an Aerovee engine.If I wanted a quick way to fly I would either climb in my Sonex or my C172 andgo flying. I am looking for the fun of building and then flying an open cockpit,slow plane like the Pietenpol. I also enjoyed the "assembly required" partof the Aerovee. And, if cost becomes an issue I'll take the engine out of theSonex and put it in the Piet.I'd still like to find someone flying a piet with a VW.Thanks again. I understand where you are coming from.--------Harv, 485PBRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Harvey,I'm definitely no expert... but for a short and quick explanation, the Piet needsquite a bit of thrust to overcome the high amount of drag. The thrust comesfrom a long prop. The VW engine makes it's horsepower at a relatively highrpm... in order to turn up it needs a small short prop. It simply can't swinga long prop high fast enough to make the power. So with a short prop it candevelop the horsepower but it does not really gain the thrust. The reason theModel A works so well is that the engine can swing a long prop at the low rpmand create lots of thrust. The old OX5 engines created 90 HP at 1300-1400 andswung an 8' prop and had lots of thrust to overcome all the weight and dragof the old biplanes. A 90 HP VW engine swinging a 5' prop at 3000 rpm would probablyhave a difficult time getting the up to much more than a fast taxi, ifthat even. For the Pietenpol you really have to think thrust. Now a VW enginewith a Valley Engineering reduction unit would become a whole different combinationand would probably work well. But there just isn't much out there thatcan beat the simple thrust of the Model A and the small Continentals.... okay...maybe the Corvair too... :-)Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 21 Nov 2012 14:56:54 -0800 (PST)
