Subject: Pietenpol-List: Alternate enginesI've made this comment before when the subject of alternate enginescomes up. Several years ago a man (Larry Harrison) in Alabama built aPiet called Poplar Piet, with the Chev. 2.5 4 cyl "iron duke" from anS-10 pick up. The plane was written up in the old news letter with a lotof fanfare given to how he found a poplar tree log, cut it up, driedit , milled it, etc. ect'ed it and built his Pietenpol with it. That'scool, but only mildly interesting compared to the engine which hardlygot any mention. He reportedly flew the plane over 600 hourssuccessfully before a crash unrelated to the engine ended the saga ofPoplar Piet. I would love to use something other than the Model A, butwant to keep the original Model A look. Unfortunately you can't get thatlook from the Corvair. Wouldn't it be nice if if some of these guys whohave already done all of the RandD and successfully tested an alternateengine make the conversion public. (Yah, I probably already know theanswer--legal liability ) I don;t have the gray matter to do this myself, but can follow a experts instructions. I would gladly pay for thisinfo. Leon Stefan in Kansas where UPS is paying for his Piet.________________________________________________________________________________Date: Fri, 1 Feb 2008 17:14:33 -0500

My Sky Scout has a 2.2 liter Chrysler. It retains pretty much the look of the Model A or T engine. It was flown, but a previous owner robbed the wings and tail for a 2 place Piet project and I have not run the engine yet so I can't comment on anything other than the looks.Brian KrautEngineering Alternatives, Inc.www.engalt.com ------- Leon Stefan wrote: > > I've made this comment before when the subject of alternate engines> comes up.

Leon. I have gn1 plans and plan on using a marine versionof the iron duke which is 181 cu in. with an industrial cam grind.They are used in the mercruiser inboard marine industry. That shouldbe close to the same type of abuse as flying. Maybe at prop speed should have70-80 hp.Bill----- Original Message -----

There are deals everywhere in unfinished projects, as there are so many of them.EAA says stuff like for every 100 plans sold, ten projects are started and onecompleted on average. Over time that adds up to a lot of projects. (Not surethose numbers really work out.. like if there are thousands of RV's flying,there would be 100's of thousands of plans out there.. probably not.) [RollingEyes] There was an add in barnstormers for a BD-4 without FWF, a woody pusher with newengine needing to be covered, a dissassembled A-65 and misc junk for 6k. Thatkind of thing could keep someone busy for a long time, or in my case probablymake me a bachelor again...Seems like there are quite a few low cost low power engines around. (Rotax's, Lyc0-145's, even some A-65's). The corvair makes a nice low cost 100-110hp engine.But seems like the more popular plane designs now are all needing 150-200hpengines, and I am not aware of any great deal engines in that range. Yearsago there were 0-290G, and other GPU's around that were being converted, but thinkthat happens a lot less now.JimRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 2 Feb 2008 07:31:24 -0500

Jim:Mazda 13B rotary form the RX7 is a litle bit unconventinal but by now aproven recipe.http://www.rotaryaviation.com/150 to 180 hp without even breathing hard and no valves to burn out.short block from aftermarket remanufacturers runs about 2500$ and theredrive 3000$.You can do even beter if you do your own rebuild.I am working on one for my Falconar.Michael Silvius----- Original Message -----

For what it's worth.One of sthe cheapest ways to power a Pietenpol with a reliable engine is to buy a midtime A 65. You can find them for between $2000 and $3500.Gene----- Original Message -----
