Hello Sir

http://www.mgchemicals.com/products/422a.html

Conforming liquids is what you need to look at. They are industrial chemicals for protecting PCBs against moisture.

You can make a spray solution out of them and spray the PCB boards of your Ardu Copter. This process is called CURING, which is often used in robotics applications.

There are other such chemicals but they are super expensive, so this one was reasonably priced.

If you use Brushless motors probabably you need not spraying them.

For sonar and other breathing parts, you might want to place a tape or cotton ball when u spray, to avoid clogging them.

You also need to follow all the hazmat precautions when handling these liquids during the mixing and spraying.

I purchased breathable waterproof fabric and tried to make a jacket for the Ardu copter, and the fabric was too cumbersome to shape.

We used shrink-wrap plastic and it worked but the sonar was the issue and before each flight u need to shrink-wrap again. Any membrane will have this problem.
