When going through the outer wings vs the builders' book I noted many differences in the use of areas for fuel.  The book showed fuel ahead of the spar, and in the outer bay past the aileron bellcrank the book showed fuel between main and rear spars out to the tip.  But in the wing itself the  fuel area stopped at the aileron bellcrank rib... and each wing tank was marked as about 18 gal. per side. Also, the wing has the aileron bellcrank outboard of the mounting rib vs inboard in the book. 

Is there still a way to check carbon sparcap thickness, and whether there are cap strips on the ribs? ... probably too late to check, as the wings are on now.

Terry,

 

You are getting much better information from those more familiar with 235 internals than I could give you.  For example, Tim Jorgensen's commentary on the wing test data.

 

The 320/360 aileron push rod is at the inboard edge of the aileron while the 235 might have that placed further outboard.  That would allow for a bigger wing fuel capacity.  I only get 17 gallons in each wing up to the rib that is positioned at the inboard edge of the aileron.  BTW, the book may have an error (gee, like that never happened before).

 

When the ribs were installed into the wing's top skin, two BID was laid up on each side of the rib.  You should be able to see this on the top skin when you look into the aileron push rod access door.  If the cap strip technique was used, then the bottom skin would have pre built flanges bonded to the bottom skin and its appearance would be similar to the rib/top-skin joints.  Of course, BID could have been added thru the push rod access door so you may have to look into the wing fuel tanks with a lighted mirror to compare the visual appearance of the top and bottom rib/skin joints.
