This pushes down on the wing (less lift), and the turbulence causes more drag. Moreover, as others have pointed out, such a wingtip is UGLY, and it doesn't look like a Pietenpol. After all, part of the charm of a Piet is the wingtip on the Hershey-bar wing. But, build it as you like.

Second, it would be ridiculous, morphodite airplane....IMHO. :P Merry Christmas everyone!

While the winglet suggestion might work, it was obviously (I hope) tongue-in-cheek and evokes a funny mental picture. The Hornier tip should theoretically increase the effective length and look neat. Whether it would be in character with Pietenpol design philosophy may be questionable though. I wonder if the Hornier tip would be harder to make than the usual rounded tip and if any performance benefit it could provide is needed by anyone anyhow. I was intending to start a Piet about 19 years ago and bought a set of plans but "life interfered". The plans may not be the real McCoy and I may need to get a set of the recognized Pietenpol plans before trying again. There seems to be at least a couple sources for plans currently available and I suspect I'm not the only one who'd appreciate suggestions on why to choose one over the other. Thanks.

In addition, the plans for the Corvair/Continental installation, extended length fuselage, and three piece wing are only available from the family. As an aside, the F&G Manuals are good to have anyways, as the text is interesting.

Over the next few years I kept in close touch with Mr Pietenpol, asking many questions just as you guys are doing with each other, as the List wasn't available. When I asked him what his opinion was on the Installation of a Funk Engine, inverted, his answer, I think that it should be an excellent engine for a " Pietenpol ". I said that the thrust line would change about 4", Mr. Pietenpol waited a moment and commented," It should work, just look at the Seabee , it also flies slow." All of my 4 Piets were not close to to Allen Rudolf's Piet, but you know guys, I have a bushel basket full of PIET HATS, so I must be fooling the Brodhead experts. In one of the comments about the Pietenpol being born on the floor of a barn 80 years, I came to wonder " I also was concieved 80 years ago also, don't know where, but I tell you guys it has been it has been a ride I'll never ever forget, just ask me.

I'm currently rebuilding the 3-piece wing w/44" wide center section) using the Ribblet 612 airfoil. Several recent pictures are attached showing the rebuild work on the flat wing tip and "boxed-in" aileron bay. The ailerons are 7' long and distance from the last rib to outer edge of the tip might be a few inches longer than the original design. The original ailerons were about 13" wide. I've narrowed the ailerons slightly to 11-1/2" to conform with the general layout of the 612 rib design.
