To add to my list of questions (not that my previous ones have generatedmany responses):7. Are any of you offsetting the vertical fin to the left, or are youaligning it with the fuselage?????Gene________________________________________________________________________________

Gene,I drilled two sets of holes so that if I find I need more offset (the firstset is on the centerline) I can do it easily. I'm expecting to not need thesecond set of holes, though. I think most Piets flying have the fincentered on the centerline.Jack -----Original Message-----

I don't know about low powered airplanes not needing the offset, have youever seen a Aeronca Champ fuselage? The fin is offset nearly an inch. ACub is offset, too. I don't know for sure about the common belief that theoffset is for torque, I believe that it is to correct for adverse yaw as aresult of P factor. I know the Cessna Airmaster I used to have had thenon-adjustable fin set in the middle, and the thing would never fly handsoff without rolling off to one side until I discovered that they originallycame with an externally adjustable rudder trim tab (which the previousrestorer had omitted for appearance sake). Once I installed the tab, itflew perfectly.I do NOT want to install a tab on the Piet if I can help it. C'mon you guyswith flying airplanes, especially Model A powered, offset fin or not?????Gene----- Original Message -----

I built it right down the middle, with the engine mount per plans ( only alittle longer) and yaw is not a problem.walt----- Original Message -----
