I once bought a used speedpassion cirtix ESC and on the inside the ESC was fully done with plastidip.
It was a nightmare to remove all the plastidip, it took me several hours to clean it.
This is something i really hate and that's why i'm designing a waterproof box to keep my electronics in their original condition.
Instead of using a plastic box of tupperware or something similar i want something that is better suited and better looking

Silicone conformal coating is the stuff you want. You just open up the ESC and receiver cases, brush it on the circuit boards and reassemble the case. The conformal coating is very thin unlike plastidip and can be easily removed with solvent. The end result is your speed controller looks unmodified but is waterproof. You can even use it on the sensor board of your motor for a little extra protection. I have seen guys use conformal coating on all their electronics in crawlers and then drive their trucks underwater with no ill effects.

last year we had a lot of rain at or national, a lot used a box wat in stock is fine, but in mod we seen a lot of esc shut down in heat protection.
Than we used a spaycan they use on elektronics in boats, never got the problem again,
it's like a thin film of clear varnish.

That's why i have the fan mounted, to get the hot air out of the box without getting water inside the box

I am new to RC but out of all of the parts out there, waterproof boxes seem to be the least available/designed or whatever. I like your design a lot. I guess a large part of it has to be that most folks just don't go out in the rain or the wet with their RCs. They are electronics after all. Here in Seattle, most on road happens at the indoor tracks. That said, there are very few dry days in the winter and even when it doesn't rain, the ground is still wet so you need all the water protection possible. Keep us updated on the box, I like the concept a lot. I would use it more for off road initially. Thanks for posting!

When i have my first electronic box 3D printed i will evaluate the box and take some pictures to post it up here.
Possibly there will be some changes i have in mind to update the boxcover.
But first i will finish this design and see where it can be improved.
Thx for the interest.

Awesome. I have some contacts here in Seattle I will ask about machining/mfging something like this, but it sounds like the cost might be fairly high. I will let you know. I look forward to following along. Do post pictures.

Anyone else remember the days of putting your electrics in a balloon? Lol

I remember Tamiya actually had their own stamped balloons for this purpose!!!
HA! I do remember that.

this is a good design but i think most motor or esc is already waterproof.

You can think it, but its not the case. Unless you're talking about boats, in which case you're on the wrong forum.

The high impedance on the sensor lines (mostly 10 kohm) can be disturbed by water. I think it can be solved with 560ohm~1k pull up resistors in the sensor wire. This is someting on my list to give it a try.

Liquid electrical tape was good enough for far more complex and sensitive equipment in the Navy (which is a far more corrosive environment), so it's plenty good enough for an ESC.

You're attempting to over engineer for the sake of over engineering.

In the first place i'm doing this for myself, cause i don't like to use whatever material that is available on my ESC or receiver and i also like a neat solution for myself.
If this is a good solution for my needs and to have something that's unique then i'm satisfied. I'm not doing this to sell some of these boxes, if there is some interest then that's fine, if not so be it.
