Is it worth making that area 2 1/2" spacing to avoid that gap?

It's a good reminder (to me, anyway), of how much force is pulling on that fabric, which in turn is pulling on those stitches. Gentle climbing turn, under 70 mph: https://www.youtube.com/watch?v=ZdcKXbX8eVw I'd stitch closely (2.5" vs 3.5") and follow other instructions from the fabric system manufacturer. This may be being overly cautious, but separation of fabric from structure has occurred, and with deadly outcomes: http://www.ntsb.gov/aviationquery/brief.aspx?ev_id 001207X03218&key=1 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=433130#433130 ________________________________ Message 8 _____________________________________ Time: 01:46:27 PM PST US From: Ray Krause Subject: Re: Pietenpol-List: She DID IT in a Piet!

I used the PolyFiber process and in their process if I remember correctly (I did this over 10 years ago), they had you glue the fabric to the ribs, then heat shrink at 250 degrees, then rib stitch, then do the 300 and 350 degree shrinks. Read and FOLLOW the manual for whatever process you are using. If they manual doesn't cover how to do undercambered wings, call their customer support line and ask them. Use their resources, not someone on an email list that may or may not be familiar with their process. Good Luck!
