5,6,7 Wing rib part numbers

[VP-22]

Great shot. I assumed it went all the way to the end of the cap strip. Now I see otherwise. Very helpful - thanks.

If my memory is correct, at least with my Kitfox 4, I think it said to temporarily mount the flaperon attachments before you cover the plane. Drill all the holes then. It would be real lousy to have a poor glue joint and push the aluminum backer off the cap strip with the wing covered. JImChuk

I agree JImChuk. Reading ahead, it says that after the wings are covered you relocate the holes by melting a hole in the fabric with a soldering iron. Yeah, that's my biggest fear that something should comes loose.

Back to the aluminum backing strips. In my manual, page W-A-19, Fig W-A-23, it appears in the (vague) diagram that the piece behind the upper cap strip goes all the way to the end of the rib. In Rick's picture it stops short, roughly even with the end of the bottom strip. Not saying it was done wrong, just wondering why it doesn't go to the end. Is it due to the way the brackets are shaped? Thanks

Just to be clear, my kit was from 1998 and this is a factory rib. I didn't install the doubler. I assume it doesn't go to the end because the 6 (3 top/bottom) rivets used to install the hinge are all over the capstrip and therefore the doubler. May have been done different on the 4. Heck it may be different from year to year.

For some additional reference - the attached photo shows how/where the aluminum doublers were placed on our early version S7 (early 2000's).

The instructions called for bonding and riveting the doublers through the rib web.

Guessing that there may be variations depending on when a kit was originally built.

Mine is done the same way. KF4 2002 vintage.
