When you install your new masts, make sure everything is clean and dry and use plenty of Locktite (blue) thread locker. Insert them firmly with a screwdriver -- no need to use the vise grips.

Downside? Better not forget to use the Locktite (Blue). It works great as a thread locker and these need to be locked in. If you loosen them for any reason, re-apply new thread locker.

They'll unscrew a threaded mast in short order if you forget to use Locktite or some other binder. Try it yourself if you have any doubts. They are relentless!
Dan, this was bound to happen. I'm sorry it had to be you, but the warnings have been there all along. With all the criticism about using too much Locktite and all the whining about the masts being too difficult to unthread, it was just a matter of time until someone didn't take the Locktite issue seriously.
I've been preaching about this repeatedly because it happened to me also -- before I got the picture. Those masts can and will unthread themselves in a NY minute, given half a chance -- even if you really cinch them down. The thing is, if the masts are still inserted but loose, it is not obvious without actually checking them.
Clean and rethread them using PLENTY of Locktite Blue, making sure they are fully seated. How much is plenty? Enough to be forced out the top of the hole and wiped off. Do them one at a time so the Locktite is fresh for each fin and you shouldn't have a problem. If you want more holding power, go to Locktite Red, but beware, you may not be able to remove them again. A third alternative would be Teflon tape, believe it or not. Use enough to make it hard to thread. I tried it for a couple of months successfully, but can't say for sure how it will work in the long term -- I switched to Locktite.
BTW just a reminder, the Drive works fine with one fin. You can make up a lot for the loss of surface area with the higher CPM available. It's always good to be current on your emergency procedures, especially out there!
