Subject: Pietenpol-List: Responses on the Dihedral questionDear Piets,Thank you all for your kind and knowledgable comments. It WAS NOT and IS NOT my intention to open the dihedral can of worms. I have from the beginning intended to build in a slight dihedral. I feel that Mr Pietenpol built a flat wing because of no other option having a continous one piece spar. My reason for the dihedral is from flying certain aircraft in past years. Three stand out in my memory. The Aeronca had a nice dihedral and was certainly a stable, forgiving on stall out and better visibility in flight. Another one I liked was the old Dehavilland Beaver. It too had dihedral and was an extremely stable craft. I don't know what degree of dihedral is built in a Cessna 172 and larger but the old military version Cessna, L-19 (O-1) was by far the most flyable and enjoyable aircraft I've ever flown. I checked my old papers and found it to have a dihedral of 2 degrees 8 minutes. This finding was the more deciding point on the dihedral.No disagreement with the straight wing people please. It's like in the military, no two will wear their hat at the same angle.LOVEPEACECorky in La________________________________________________________________________________

"Richard Navratil" That was very easy. After completing the scarf joints on the spar sections,I laid the spar on the 30 long table I had built. It had a true edge on thefront side. I marked the center line and end points. I simply screwed in ascrap piece of wood at the ends marked 1" high of center. Then just glued,nailed and clamped. Installed the plywood plates later.Dick Navratil----- Original Message -----
