I flight all the time on the ocean, and here have a lot of humidity and salt. So where can I use something like Ultra Ever Dry in the electronics? Flight cntrl, Navy, Distribuition board, motors, GPS, etc.....? Thanks Ivo
Ivo, welcome to the forum. If it's not too much trouble, would you be kind enough to change your user name to your real first name and last name, please? The reasons for this (and how to do it) are explained here: http://forum.freeflysystems.com/index.php?threads/real-names.497/ Thanks Andy
I think you're going to need some kind of cover for the electronics. Those products are pretty limited in what they can do. If you're close enough to salt water for your copter to get wet, you'll have to protect it. There aren't really any products that I'm aware of that can do that. But if you have access to a 3D printer or CNC machine, you can probably design something. But be aware that if you seal up the power distribution board you may have problems with overheating.
Atmospheric humidity is no problem at all. If you have salt spray, that is another issue. Get some conformal coating from an electronics store and coat all your electronics boards with it that might be exposed.

Self serving or not, that guide is quite good for beginners. I use Frog Tape for masking, its much less textured so the edges dont bleed. Green is the best for this sort of application (the medium tack).
