Subject: Pietenpol-List: Trailing edgesI have a question....The plans show using wooden trailing edges, but I have also heard of some using aluminum trailing edges. I assume this would be a weight saver. I was wondering if anyone out there might have input on the use of wood vs aluminum on this portion of the project. Strength, rigidity?? Obviously I do not want to divert from the plans, however I am interested in saving some weight for the model a. Thanks in advance.Walt________________________________________________________________________________Date: Wed, 3 Oct 2001 08:46:39 -0700 (PDT)

Hi Walt,I used aluminum trailing edges on mine. They not only save weight, they arestraighter than most wooden trailing edges. Another concern with wood isrot, since the trailing edge is at the low point of the wing and willcollect moisture, drain grommets or no.They may not be suitable for "purists", but I'm sure BHP would have usedthem if they were readily available in his day.Jack Phillips-----Original Message-----

Jack, Hi,I'm an 'almost' Piet builder living in Belgium. I've just bought a set ofdrawings and am getting ideas together. What kind of aluminum did you use -tubular section, or a V section, and how was it attached? Anything to saveweight must be good! Grateful for your advice.Phil H.----- Original Message -----

Hi Phil,I used the V section aluminum Trailing Edge material that Aircraft Spruce &Specialty sells. It costs $10.85 (USD) for a 10 foot (approx. 3 meter)section. It will take a total of 4 sections to do a Pietenpol, so $43.40.The savings come in the installation time. It took me about an hour to dothe entire wing. I hate to think how long it would take to do it in wood.If you don't have their catalog, it's free and can be ordered atwww.aircraftspruce.com . It is a valuable source of information, and theirprices are not too bad (by aircraft standards). I have bought a lot ofhardware and about half my wood from them. I believe they ship worldwide.Good luck,Jack PhillipsWings finished, Tail finished, Fuselage nearly finished, Landing Gear underconstruction and nearly finished.
