I take the easy way to keep all electronic stuff dry.

I rough sand the hull next to the main motor and epoxy in a vertical piece of THIN plywood.

Everything electronic goes on it. ESC's would be right over the motors. Leads reach easily. The ESC's receiver plugs get pluged in the receiver and it is mounted close to the front of the boat.

Leave enough slack so you can plug or unplug the ESC's easily.

The antenna does not need to be vertical and outside on the deck or mast. Run it to the inside of the hull and around to the bow ( nose ) and back on the other side. Keep it about 1/2" below the deck.

I have never needed to twist leads, or need suppressors. I run 40 # thrust trolling motors from Bass Boats in mine. At 14 vdc and surges to 80 amperes. Never a twitch.-------------The reason may be I use a very good Novak Super Reversing Rooster ESC. It runs a small 400 motor just as smoothly. I have 2. 1 was accidently hooked up backwards by me and suffered no problems 3 years ago.---------ALWAYS put in a car circuit breaker or a fuse in the + battery lead to stop fires.------It tripped instantly on the dead short due to the reverse hookup.

I have used 2 standard servos as main motors and the ESC's, in a Lindburg Blue Devil destroyer. They can be used in 8" models if you use a smaller size servo.


If you like I can show a picture in this post of how simple it is.
