Let's hope so. I haven't had much joy with DIY waterproofed servos. Unless you can absolutely guarantee no leaks they represent a maintenance chore (You try them after several months and they have rusted etc.) Or you put them in a nice big, strong case and they don't fit anywhere! Slim commercial servos at a sensible price would be very welcome but still not for essential functions,in my opinion.

An interesting (and developing) thread over on Model Boat Mayhem about the waterproofing servo perennial:

Servos seem to be developed as water proof but not PRESSURE proof which is what we need.

The consensus is (I think!) don't do it.

I've just checked and that Hitec servo is available for £27 on ebay which is not TOO expensive. It is IP67 rated which I think allows for a meter depth of water.

So it may be worth using them but I still wouldn't use them for anything critical (ballast control etc.)
