When I lofted the dimensions from the plans onto my rib jig, I noticed that everything lined up wellwith the full size rib print except the rear-most vertical member in the rib. The full size print has this part almost 1" further forward than what the plan dimensions show. This will result in a shorter chord dimension on my finished ailerons. Looking for what the finished dimension should be close tofrom the hinge line to the trailing edge... would anyone be willing to throw a tape measure on their aileron (OK - lay it gently on...) and see what you comewith?Currently am at the "got a bunch of big sticks and cut them into little sticks" stage and am quickly gearing up for the "now glue them back together tomake ribs" stage.Dan LoegeringFargo, NDDan,I built 2 extra ribs over 7 years ago. They make great wall hangings !! Here are the results of the measurements that I just took:From the aft edge of the rib (where the trailing edge goes) to the aft side of the rear most vertical member is - 10 1/2". The plans call for 11 3/4".From the aft edge of the rib to the fwd edge of the aft 1" spar opening - 23 3/16" The plans call for 24 1/2".Between the openings of the 1" Spars - 27 3/4" The plans call for 27 3/4". This is the most important dimension, because it is what the center section, and lift strut points are built to.I used 3/4" spars, therefore I had to use 1/8" shims on each side of the spars, at each rib location. If I would do it again, I would build the ribs touse 3/4" spars so I wouldn't have to shim them, yet maintain the center to center dimension of the spars, which works out to be 28 3/4".My total wing chord, with leading & trailing edges installed, came out to 60 1/8".Chuck G.NX770CG________________________________________________________________________________Subject: Pietenpol-List: Re: Aileron / Wing Chord QuestionDate: Thu, 13 Oct 2005 08:34:16 -0500
