Subject: Pietenpol-List: Re: Pietenpol-List thrust line.....Pieters, I just put my wings on in the machine shed and I gave the top longerons a quick angle measurment and came up with 14 degrees. Now part ofthe problem is that I started out with 6:00 x 6 wheels but then went to 21 inch motorcycle wheel which raised the axles about 3 inches. I think 12 degreesis normal and wonder how it will handle, Sure looks high but easy to prop. This was measured empty but with my 230 pounds in the back seat the tailwheel will probably deflect as much as the mains. Any comments would be appreciated.

One word of caution, when you get to flying. Make sure that you get the tail upearly on takeoff roll. It can want to lift off before it's ready to fly. Ifcan lead to a stall in ground effect.Dick N.----- Original Message -----

Ken,Mine has 21" wheels and a deck angle of about 13 degrees. In the threepoint attitude it is right at the stall. I think 14 degrees might be just atad too much. You can always extend your tailwheel down a bit further todecrease the deck angle. That would be a better solution than changing theincidence of the wing.Jack PhillipsNX899JP-----Original Message-----
