Lengthen the wings, change the cord, reposition the tail surfaces, as well as enlarge or change the shape of the tail surfaces. Then you can fly these changes to see howthey fly. I think FMS is another Simulator, one that already has a Pietenpol data file for it. The structural changes you'd have to take on yourself however. Changing one thing at a time would be the best thing to do.________________________________________________________________________________Date: Sat, 06 Dec 2003 20:22:59 -0500

ESPECIALLY, something like the wing !! The required engineering involved wouldbe in depth. The Pietenpol is a well proven design, and if you change the wingspan,you change stress points, the size of the empenage, trim drag, inertia effects, component size, bending moments, and a host of other things. Don't changethe wing !! Build it to the proven plans.

There's someone over on the west coast of Florida who stretched the wings onhis Piet. Can't remember his name and I can't find my notes right now but Isat in his plane at SNF 2003. It was stretched 4 feet (not sure if that wastotal, or per side) and the plane has been modified to look a bit like aCurtiss Jenny. Said it flew just like a Pietenpol... not sure the reason forthe change though.-Mike> wingspans?

There was a fellow on this list from South Africa who used to fly a piet with the wings extended quite abit because of an extra wide center section ( six feet if I remember right). He came to the list trying to figure out why the tail would stall before the wing making landing a very exciting manuver. He finally ended up crashing it. I believe he wasn't hurt too bad but we haven't heard from him since. And remember....when you tilt the seat back back you are moving the C/G of the pilots head and shoulders aft, something we need to be careful of. Bernie did all of the calculations and experimentation for us so that every thing works together....When you change something it almost always affects something else. And besides...it's so much faster and easier to follow the plans.
