Hi Paul,After several years of being on this list I have observed a bunch ofquestions. Here is my own list of common questions:1. What wood should I use? Sitka Spruce has the best strength to weightratio of any wood. It is also considerably more expensive than some otherspecies, such as Douglas Fir. Many Pietenpols have been built with fir,cedar, hemlock and other woods. I built mine of spruce, just for itslightness and because it works very easily. It is also the only "aircraftgrade" wood you can find. Common sources include Aircraft Spruce &Specialty and Wicks Aircraft Supply. The cost of the wood is less than 10%of the total cost of the airplane, and is not a place I would look to forcutting costs.2. What glue should I use? Nearly everyone now is using T-88 epoxy, withgood results.3. What engine should I use? Hah! Lot's of people are using modifiedCorvair engines, many use Continental aircraft engines from 65 - 100 hp, afew use Lycomings of 108 - 115 hp, many still use the Model A Ford enginethe airplane was designed for. Your choice. The tradeoff is generally costvs reliability. If I lived in the midwest, where forced landings are notgenerally a problem, I'd use a Model A, or a Lambert radial, or somethingequally interesting. Since I live near the mountains and fly frequentlyover fairly inhospitable terrain, I chose a Continental.4. I'm 275 lbs and want to carry 400 lb passengers. Will I be able to flya Pietenpol out of my 1200' strip? No. Either lose a bunch of weight orbuild Van's new RV-14. The Pietenpol was designed at a time when theaverage pilot really was 160 lbs, and it didn't have a lot of room for them.The inside of the cockpit is only 22" wide and the plane really doesn't havemuch load carrying capability. 300fpm is a pretty average climb rate with65 hp - less on a hot day. With 100 hp you might get as much as 500 fpm,but it is highly dependent on load.5. Can I add a door to the front cockpit? You can, but it adds a lot ofweight, reducing the ability to climb with that person in the front thatneeded a door anyway. Better to limit your passengers to 180 lbs or less.If they are that small they can usually manage to climb in.6. Can I change XXX (fill in the blank, here)? Yes. It's yourExperimental airplane, so you can change anything you like. Will it fly aswell as if you built it to the plans? Almost certainly not. I've flown anumber of Pietenpols and without exception, the closer they were built tothe plans, the better they flew.If you don't already own them, buy the 4 Tony Bingelis books: TheSportplane Builder, Sportplane Construction Techniques, Firewall Forward,and Tony Bingelis on Engines. Nearly every question you can have inbuilding an airplane can be answered in those books. They are availablefrom the EAA. You are an EAA member, aren't you? Even though theleadership has changed and the organization seems to be struggling to findits direction, it is still a worthwhile organization to belong to and is agreat storehouse of information on homebuilding.Any other questions can be answered on this forum. Just try to answer themfirst using the forum archives so you don't ask a question that was justanswered a week ago.Good luck!Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____
