Look at http://www.halcyon.com/wanttaja/engines.html for a good sourceof engine info including the horsepower and weight specs of thepowerplants involved. Also, from memory, I think the model A engine putsout about 40 hp and weighs about 240 pounds.Andy Schneider________________________________________________________________________________

Ed, you might get it off the ground solo, at sea level, but I think you willreally want the extra power. I would consider 65 hp minimum. If you canget 90 to 100 hp you will be pleased with the climb performance with twoaboard. I havn't tried to find parts for the -40, but they will be rare.-See you at Heber-Stevee-----Original Message-----Larsen, EdSent: Monday, September 14, 1998 10:20 AMSubject: Pietenpol-List: RE: Engine Info SiteWhat is the minimum hp required to power an Air Camper well?

Ed,It would appear that an A-40 would fly a Piet if it would fly a J-2. Thereis a very early production J-2 at Brodhead. I read an article in an oldBPAN where the guy thought the Model A Piet would out perform the A-40 J-2.I think it is likely as a converted A probably puts out more hp than a A-40,and more importantly, more torque. A draggy airframe like a Piet likes theslow turning prop.The A-40 would have a weight advantage which if properly exploited wouldmake up for its low output. However, what I have observed with a lot ofhomebuilt airplanes, especially Piets, the weight advantage of thecertificated engine is more than offset by the useless junk added to theairframe by its builder. I.e.: brakes, tailwheels, radios, electricsystems, batteries, bomb racks, refrigerators, machine guns, airconditioning, canopies, fat women, armor plate etc, etc.Brian Kenney's Piet is said to be the lightest one on Earth. About 585 lbs.It has (I think) a 50 hp Continental, and is a good performer and goodflier. I know of another absolutely beautiful ship with a Fiesta that is a800+ lb monster. It flies as the result of having enough hp to drag itaround.I ramble on a bit to say that what I have learned from listening to a lot ofbuilders is that the key to a successful Piet (as well as any other type) iscontrol of weight. Take that part you are considering adding to your ship.Throw it up in the air. If it comes back down, its too heavy.John-----Original Message-----
