Sanity check

[Ed Alt]

John:
Unless you have a detached end plate support, you can usually just inject 
the foam with polyurethane glue, such as ProBond poly with a hypodermic 
needle, clean up the goo that bubbles through the holes, sand and recover 
that section. However, I had a problem on my Focus II where there was simply 
not enough glue used when the wing was built and had to open up the bottom 
along the entire length of the tube socket, re-glue the end plate support 
with epoxy (was completely detached) and then built up the crushed foam 
around the socket.  No problems after another 130 flights or so since then.
