Jorge--Many years ago, during the 1970's I think, a canadian named Ed Lubitz brought a Fiesta-powered Piet to Oshkosh several years in a row. It had a rubber cog-type belt drive to get prop RPM down while letting the engine spin up to rated horsepower for takeoff. It flew well and I personally measured several takeoffs comparable to a Piper Super Cub! It was a kick to watch since it seemed to levitate. He marketed plans for the belt drive for several years and I was going to use it on my Piet, but Fiestas are no longer available in the US and so I have gone back to the Ford A engine.Mac in Oregon ----- Original Message -----

The "A-Frame" for the tailwheel/skid makes a great handle. I pick up mine to moveit all the time. It is easier to move like that than it is to push the planewith the tail down. Just reach down through the rudder and elevator cables.The more you think about the basic design and how you might improve it, the moreweight you add! Build light! Have yet to talk to a Piet pilot that regretsbuilding too simple and too light.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: I am thinking about using this engine in an Aircamper

It's a Holden 138ci 6 cylinder Grey Motor. 120 ft/lbs torque at 1400rpm, Witha bit of work I am confident I can get 65Hp at 2000 rpm and get its weight inat 250lbs. I want to run direct drive. What are the opinions on this. I can geta Model A engine, but since I am building it here in australia, I would reallylove to power it with an Australian made powerplant. The grey motor has thebest torque figures at the rpm i was wanting, is the smallest, and the lightestof all the straight sixes, Ford, Mopar, and Holden/Chevy.CHarleyRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Pfeifer Sport plans

Original Posted By: "K5YAC"
I had a very strange feeling today=2C like nothing I've ever felt in an airplane before. I took 41CC out on patrol but stopped for fuel first. No big deal=3B it was just me and an aerial applicator at Castroville so I took on my fuel quickly and headed out for Medina Lake=2C about 15 minutes away. Flew out over the lake=2C then checked to see if my friend Norris was over at River Ranch working on his Breezy (he wasn't). Then I headed northeast to take a picture at Freedom Springs. While flying back to my home base I decided to climb to a couple of thousand feet. I put in full power and put the airplane in a climb=2C which it did without complaint=2C and we leveled off at 4000 MSL.It was in level cruise at 4000'=2C the highest I've ever had the airplane=2C that I felt a very strange uneasiness. I felt like we were up too high! The ground was way down there=2C or so it seemed. I didn't feel like Icarus (who flew too close to the sun and melted his wings off)=2C but it was a peculiar sensation. I've been over 10=2C000' in Cessna 150s=2C Tomahawks=2C and other small planes by myself so it wasn't the altitude... it was just something about me and the Air Camper. I guess we belong down in our comfort zone... "low and slow forever".BTW=2C on the way up to 4000' I did a power-on stall and found that the airplane will hold attitude with power on down to 30 MPH and probably even slower=2C but it was obvious that the angle of the pitot or the oncoming propwash (or both) made the ASI read erratically at anything less than about 32-35 MPH indicated so who knows how slow it will fly with power but it's pretty slow.Another 1.2 hrs. in 41CC=2C who is getting to be a very close friend and companion.Oscar ZunigaAir Camper NX41CCSan Antonio=2C TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Subject: Pietenpol-List: Re: high flight

Subject: Pietenpol-List: high altitudes in a PietOscar-- I have the same sensation when flying my Piet above 2500-3,000 feet forsure. There is something different about flying that 24" wide fuselageup that high with all that open air around you. (not to mention that you haveto take an extra day's leave just to climb above 3,000 feet in a Piet) Regarding the Bernie vs. Bernard comments, would it also be a dishonoring thingto call a Piet a Piet instead of the formal Pietenpol then ? Also, who exactlycan be quoted that knew Bernard directly who could comment specifically that hedid or did not care for being called Bernie ? Many "well known" facts aboutthe Pietenpol turn out to be heresay and old wives tales that are started and justpassed along without thought or fact---just curious is all. One thing Idoknow is that Pietenpol was a very odd duck personality type--much like his followers!

Oscar (and Mike C.),I can't agree with you more! I just do not like flying very high in my Piet. It feels like I'm going to tip over! I know that sounds crazy, but that's howit feels! I once found a hole in a broken layer and climbed up through it. Once on top it was absolutely exhilarating. As I looked down through the holesand could see the ground way down through there, I suddenly couldn't wait toget down close to the ground again! It must go along with the fact that I justcan't stand heights. Go figure. Can hang out the side of my cockpit all daylong. Can hardly bring myself to hang Christmas lights on my gutters!Low and Slow FOREVER!Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Oscar &Mike C.,I have had my Piet to about 4000' agl (approx. 6500' asl in this area). This was in the early 1970's when I had an A65 in it, and it took a LONG TIME to get up there. I have had a C85 in it since 1974, with a much better rate of climb, but never again flew that high because it was just too darned lonely and cold. I can't even imagine those fellows in WW1 flying Sopwith Pups (about the size if a Pietenpol) at 18000' to 20000' on patrols. But Arthur Gould Lee in his book, NO PARACHUTE, tells of doing just that!Needless to say, the Pietenpol airplane is best suited to the lower levels. "Low and slow" is the most fun, anyway.I have yet to fly my Pietenpol this year because our weather has been simply horrible. That situation, however, will soon be corrected.Graham Hansen (CF-AUN in Alberta Canada) ________________________________________________________________________________Date: Sun, 10 May 2009 05:24:27 -0700 (PDT)

My opinion would be, test stand proof.Prop pitch to turn 2400 RPMRemove all steel that is replaceable with Al.Pan, rocker cover etc.I think that is a vacuum pump under the fuel pump, got to go.Replace pulleys that are required with Al.Compare this engine to a Ford Fiesta, on a Piet flown from the East coast toBrodhead.The weight can be trimmed to be Pietenpol worthy, but I think it may be a bitshy on CIs. to haul 2 heavies on a warm day.It will be a smooth runner, at 2200 RPM.The spark advance must return to retard, or she will snap a finger or two, withthe Ign. system I see, when hand started.Pieti LowellRead this topic online here:http://forums.matronics.com/viewtopic.p ... 421#243421 ________________________________________________________________________________

Mike, when you talk to Vi, he always said "Bernie". as I recall, when I spoke toBernie, I called him "Mr Pietenpol". He sure was a great guy that had time foranyone and every one. My red Piet With Funk engine's number was , the yearBernie was born, the year he died and BP. And I just flew her to Palmyra for it'sannual yesterday. The owner, JoBeth Barrett, trained in the Piet to get taildraggertime, before flying her Stearman.

Rob,On the certified planes, they know because they're all built the same.But in our community, where they are all built with different weights, and different power plants, I'm sure the numbers would vary Very greatly.I built very light, and it climbs great. So I'm sure that mine would go very high.But like the postings of recently. I haven't got the chops for it.Always been afraid of heights, and when I get to 2000AGL, I get the creeps.Think it's the feeling up high, that you can't tell the attitude of the plane.I can zip over the trees at 500 feet all day, cause you can see when you are yawing right or yawing left.Up high you are hanging by a thread, not moving. Sometimes I'm up high and look down at the panel and the ball is way over to the side. I have no sensation of attitude. Don't like it.Low and Slow is what I likewalt evansNX140DL ----- Original Message -----

Rob,The FAA's definition of service ceiling is the altitude where, at grossweight and max rate of climb, the rate of climb produced is 100 feet perminute. Based on that, my Pietenpol's (745 lb empty weight, 65 hpContinental) service ceiling is just above sea level. At my listed grossweight of 1245 lbs (full fuel, 2 200 lb souls and 10 lbs of baggage), on ahot day I get right at 100 feet per minute climb. A cool day makes a bigdifference, as does ANY lightening of the airframe and/or pilot andpassenger. On a cooler day with me by myself, half tank of fuel and nobaggage, I can zoom right up there at close to 500 fpm. Think of this asthe best of all reasons to go on a diet.Jack PhillipsNX899JP _____

Flying home from a fly-in one day, I decided to see how high I could get. In 45 minutes, I was at 9,000'. This is with an A-75. I don't know what my climb was, but it wasn't much, but I was still going up. The limit probably would've been somewhere below 11,000'. Somewhere I even have video of it. It felt like I was suspended from a string...I couldn't perceive any motion. I would've kept going but I started getting cold...it was in the 60s on the ground, and in the 30s up at 9,000'. I wasn't dressed for it.Steve RuseNorman, OK ----- Original Message -----

LarryI carefully read the article and very much agree with what the author and you said. However, some airplanes are designed precisely for a particular engine specified and all components carefully engineered. You will not find barn door hinges and fence wire in a Sonex plan. Times have changed and some materials have had improvements which can lead to a far safer aircraft. I fully realize that was not in anyway the focus of your comments and many of us remember what you were referring to. The "FISHERMAN" being one memorable one. There have been some wild ideas floated on this list over the years and I suspect that some are just typing too fast after working on the project and having a couple of beers. What about the idea of long range tanks for invading Cuba from a couple of years ago, Hi Corky.I wouldn't tell Lowell Frank he didn't really have a Pietenpol when he had the Warner 145 on his plane, There were 2 Piets with O-200's at Brodhead weighing 810 lb. My Rotec Piet weighs 810 lb. I called that Piet a Deluxe Pietenpol, partly for humor and partly to note the changes that I made to the design. When I started that project, I found a number of people that didn't appreciate that I was doing something different and when I was driving it in the trailer to Brodhead in '07 I was worried that it wouldn't be appreciated.Bernard Pietenpol tried a variety of engines and there are 4 different fuselages in different plans available. With the different body types of owners, some have had to make adjustments to fit. I don't think that disqualifies the plane from being a Pietenpol. Dick N. ----- Original Message -----

As mentioned in other posts in the archives=2C the Fiesta "Valencia" or Kent engine was used extensively in many automobiles and many countries around the world so there are plenty of them out there. I have no idea what is involved in the conversion but my guess is that there are a lot better candidate engines available here in the U.S.... but Jorge is not in the U.S. so he may have better access to one of these engines than we do these days.I'm surprised there are no Piets flying behind the Fiat Panda engine.
