Hi,I didn't want to hijack the High Altitude Pietenpol thread and decided to startmy own.I currently live in the Chicago are and am considering starting a Pietenpol/Corvairproject.There is a possibility that within the next couple of years I will be moving toLongmont, Colorado.How well will the Pietenpol perform as a two place airplane flying in the Longmont,Colorado area?Thanks-Glenn--------This e-mail was written using 100% post-consumer recycled data.

The short answer is that it depends on the engine and the propeller.Longmont is not actually in the mountains, being about 20 miles east ofBoulder, as I recall. Still, field elevation there will be about 5,000'.If it were me, I'd put an O-200 Continental on it and stop worrying.Jack PhillipsNX899JP "Icarus Plummet"Smith Mountain Lake, Virginia-----Original Message-----

As previously stated by Ken,I have an O 235 putting out 125 @sea level.At 78 F density altitude of 8000' I am off in 650-800' at 1175lbs.Can get up to14,000' on a cool morning.I wouldn't have a smaller engine on a bet unless youjust want to fly in the winter and fly east to cranksnappin country.dave--------taking to hangarRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I ran the Riblett and the FC-10 airfoils through X-Foil airfoil simulation software. I really, really need to find the time to do a better analysis, but my preliminary findings are that the Riblett GA30-612 airfoil is a bit better than the FC-10 by about 10%. That is, it will climb about 10% faster, and glide about 10% farther than the FC-10. Other advantages - it's thicker so you can put a bigger center section fuel tank in there. It still looks like an FC-10 with the under camber. Disadvantages - it's not a pure Pietenpol design and you will garner the derision of the purists. The FC-10 is a fine airfoil, too. It cruises faster than a Cub's USA-35B.

Gentlemen,This is a very interesting topic, especially since I am so new to the world ofPiet building. May I ask where you find all of these different airfoils and such?I wouldn't mind learning more about the Riblet, as it sounds like a more comfortableand viable option for long flights the wife and I will be partakingin... as I am sure we will have to hit high altitudes somewhere going from westcoast to east coast.
