What is the best way to waterproof a servo. Just recieved my first pair of floats and hope to be flying dry this weekend. Just to be protected, what do I need to do to waterproof my servo's? I assume I wrap my RX in a bag and seal with wax?
I fly a couple of float planes that also serve as land planes. In fact I flew my little electric Piper Cub off the local pond today... it was like taking off from glass... wonderful.
I haven't waterproofed anything on my planes, or taken any precautions against splashes. No damage or concerns yet. I did dip my Cub in the pond a few weeks ago, the airframe got a little wet, and the wing servos got soaked, but after it had dried out everything worked fine.
I wouldn't worry too much about extreme waterproofing. Unless the water is REAL bad with scum or pollution, the water won't do much damage if it is cleaned out quickly (within a few hours). Just remove the covers and soak with IPA and let it dry.

I don't go overboard on waterproofing the electronics on float planes. Go ahead and wrap the receiver in a bag. Also look for places where water could enter and seal them. For example, the wing saddle. Run a bead of silicone sealer along the saddle. Lay some plastic wrap on top of it and then install the wing, but leave it a bit loose. Let it dry for a day, remove the wing and peel off the plastic.
There is a water displacing compound called Aeroplate that will waterproof the circuit boards on your RX as well as your servos. Just spray it on and it will shield your electronics from water. It is non conductive so it is safe on live circuitry. I'll give you 2 links to peruse at your leisure.
