Default How to waterproof your electronics

I've been thinking about the best way to waterproof my electronics.
So i've been busy to draw something in Autocad Inventor and this is what i've been designing so far.
I did design the box with a slot that goes arround the lower part to fill up with a rubber sealing or some Cleaning gum (wich is excellent for keeping the water outside of the box.
This is the complete box, upper view.

Lower view, on the right side you see some slots for the motor and battery wires and on the left side is an opening for the servo wire.

A look on the inside of the lower part of the box.

This is the rear side of the box and as you can see there is an opening for the antenna wire.

Here is a look on the upper part with a top view.

And a look of the underside op the upper part.


This box will be 3D printed to see how well it all comes togheter and to see how it fits on the chassis.

What do you guys think about this?

Just go to Maplins/Radioshack etc and buy a box;



You want to be able to seal it completely because anywhere air can get in so can air with moisture in it which will condensate.

Most of the pilots use plasti dip and so did i but i really don't like the time consuming effort to do that.
I once bought an ESC and the inside was done with plasti dip, it took me about 2 hours to get all the plasti dip out.
That's why i came up with the idea to design a box that looks a lot better then most used solutions and to keep it as low as possible.

I've done some more drawings of my electronics, this way i can see if they all fit nicely or am i able to see how much space is left when changing the position of the electronics.
My Muchmore Fleta ESC

My Futaba R603FS receiver

Here you'll see my personal transponder located in the upper parts of the box.

And here are my electronics installed in the lower part of the box.

Here's another update on the upper part of the electronics case.
After some measurments i came to the conclusion that it's possible not enough space for the out going motor/battery wires so i created some extra space for those outgoing wires and i also relocated the space for mounting your personal transponder.
Here's a picture of the updated part

Another small update for sealing the out going motor&battery wires.
I'm hoping the black/gray piece will be in rubber, this way i can get a good waterproof solution.
Here is a picture of what i mean.

Here is a new design of the cover.
Now there is a possibility to mount a fan (25mm) to get the warm air out and still make sure the water stays out.
It's been designed with a special air ventilation system to avoind the water coming into the box.



Here you can see the system i've added to mount the fan on the underside of the cover, fan will be kept in place with a double sided tape.
The blue section is to mount a personal transponder and the green section is where the wires need to come out of the box.

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!!!

This is a really neat way of doing it. I'm excited to see how it ends up

I still do, with at the end some cleaning putty to seal it all off. Even now with reciever boxes I still put the receiver in a baloon, better be safe than sorrow.
