Are they on most of your airplanes???I would think that anyone who has built a '33 fuselage (I can't speak to thelater plans) would have noticed that the lower fittings are closer together than the wing spars (i.e. the upper fittings) and dealt with it, either by correcting it or leaving it as is. Which is it??Thanks for any help . . GeneGene,To tell ya the truth, I don't know if the lower strut fittings on my plane is 28 3/4" apart, but I'll measure them next time I'm at the airport. It stands to reason that the lift struts pivot points should be within 1/8" of being parallel, reason being the unique feature of the Pietenpol's movable wing position. Keep in mind the entire usable arc is probably about 3=BA. I think the reason for the 27 1/2" dimension called out between the fittings on DRAWING NO.3, is because there is an offset of the pivot point of the lift struts (from the centerline of the fitting), to accommodate the flying wire attach point.The important thing is to maintain enough edge distance of the holes in the fitting and the wood. Just exactly what is the dimension that you are coming up with between the pivot points of the lower lift strut fittings ?Chuck G.NX770CG________________________________________________________________________________
