Subject: Pietenpol-List: vertical stab flexible at front endMike, You write: "now that I have it all bolted to the>fuse and have my newly made brace cables in place, everything seems>solid...except for when I grab the leading edge of the vert. and push>sideways on it, then it flexes/twists." Mike-- simple solution. Don't push on it. Not trying to be smart butseriously, many parts of the plane flex and are meant to like wings on an airliner flex way up under flight loads and move around in turbulence. The photo Oscar shows is fully acceptable but isn't the norm and might be a GN-1tail from the looks of the wide gaps and eye bolt hinge types (as found on GN-1's)Much of the structure will tighten up greatly after fabric and paint have beenappliedtoo. Also if you go with the two-fitting location on the vertical fin you'll havetwofittings more, two more bolts, nuts and washers that you don't need as well. Justmy thoughts. Either installation is totally acceptable though. I simply wouldn'tworry the flex. Hundreds of Piets are flying with the single, rearward attachpointto the fin with no problems.
