Axial AE-1 ESC - Waterproofing

Another thing that I did few weeks back...

My Honcho's ESC is previously housed in a small waterproof box until lately, I thought the ESC is getting too warm when the Receiver glitches intermittently. So I removed the ESC from the box and waterproofed it. The receiver still glitches whenever the servo is exerting high force, and i suspected that the low current BEC in the Axial AE-1 ESC is causing the problem.

So, I added an 8A BEC (a little overkill for powering 2x high torque servos, one for steering, one for Dig, and to power the receiver) and it solved the glitching problems.

Back to the waterproofing part.....

DISCLAIMER:
TRY THIS AT YOUR OWN RISK... I WILL NOT BE RESPONSIBLE FOR ANY DAMAGES...

In our part of the world (Singapore) PlastiDip, Liquid Tape, and similar stuffs seems to be non-existent... I searched around Singapore's hardware stores, and nobody seems to know about such a product.

What is easily available in our part of the world is Silicone Sealant. WARNING: PLEASE ONLY USE NEUTRAL CURE SILICONE SEALANT, Neutral Cure Silicone does not release acid during the curing process. This acid will corrode the PCB and destroy your ESC.... BEWARE!

Neutral Cure Silicone usually is odourless, and it is indicated on the package. Be careful when shopping for Silicone sealant.

I used the Silicone to waterproof like how the guys in the other parts of the world do with PlastiDip and Liquid Tape... I opened the AE-1 ESC case and covered the whole PCB with the neutral cure silicone and the it dry totally before putting the silicone covered ESC back into the AE-1 plastic case.

Below are the pictures.
