RE: Skymaster Hinges
Bill,
I had similar probs on my 2m VJ. 2/3 hinges snapped, one during installation (with glue drying of course) and the second during radio setup.
My recommendation: cut the hinges from the side with a Dremel (just to separate the rudder), and then use a soldering iron to melt the hinges out (I used sharpened brass tubing that just fit around the hinges and drilled them out, but that was a pain), and reinstall with Robarts (they are much more resilient and 'tight').
