I noticed that there is some very small vertical play in the wing adjuster on my Passport. Two wing halves could rotate maybe 0.1 degree up and down. The root cause is that the threads on the nylon post start to wear off.

Questions:

1. Whether the adjusters from CA Model are compatible with Gator RC's version;
2. Whether there is an easy fix that would last a while (contests coming up) before they are replaced.

thanks in advance.

As a quick fix, you can try wrapping some teflon tape around the adjuster screw thread. It adds some thickness to the threads and eliminates the vertical play.
It worked for me.
