Subject: Pietenpol-List: External wind driven airplane generator on Ebay (questionsanswered)I've had several off-list questions about the generator I have listed on Ebay. I tried to add additional pictures to address the questions, but it seemsonce someone has placed a bid on an item, you can't add a picture. I'm happy tosend extra picture if you'll contact me through the auction. I think it would be an easy task to make a quick release plate for this. I have see belly pods on Avid's and Kitfoxes that were bulkier and heavier and I believe this would be an easier install than a belly (cargo) pod on an Avid.#1. The unit stands about 11 inches tall. That would make it hang about 10 inches below the belly of an airplane.#2. It would best be mounted in the slipstream under the belly. The instruction manual suggests it cranks out 10 amps at 80 mph, and that can be achievedunder the belly of an Air Camper, unless you are at idle engine RPM.#3. The prop on the generator is made from aluminum and it looks to be cast. The "hub" is machined so should not slip on the shaft. The blade looks be about 5 inches on each side.#4. I think the best place to mount would be directly under the passenger and some kind of plate on both sides of the wooden floor would be needed to provide reinforcement. Doubling the plywood with an extra layer should do, or twoplates of aluminum about 8 inches wide and 10 inches long should work.#5. I was told from the person who purchased it at an estate auction in Michigan last year that it appears this generator has never been in service. Theoriginal owner passed away and it was in a hanger with a project airplane. Theonly paperwork that came with this was the 8 page manual and on the front it states "FAA/PMA" thus the reason these things are expensive when new. The manualis dated 1998, so I suspect this generator is 6 years old. I think it would provide years of service and it looks like it would be easy to put new brushesin it, should they ever become worn. ________________________________________________________________________________Date: Thu, 09 Dec 2004 12:27:56 -0600
