So as I was reading on here about waterproofing I came across a thread about sticking your electronics in a little project box that you can buy at Radio Shack, Well I bought one an it fit perfect inside the axial chasis and after drilling some small precise holes for all the wires to exit and drilling 2 hole to mount it to the chasis using the body mount holes and body mount scerws to lock it in I was able to put my reciever, castle BEC, and my FX-R ESC inside along with all the wiring. After putting everything inside and screwing the 4 screws in to seal it I then sealed the seam with a removable silicone bead around the seam and in and around all the holes it is now 99% waterproof. I say 99% because I havent givin it a swim just a bath! Thanks for the info from where ever it came from but it only took a few minutes to build and now all my elec. are both smash resistent and water resistant. THANKS!!!!

Great tech here.

in my case using the SCX10 platform,

had to pull the electric board right out of the Reciever box,
then placed it inside the SCX10 radio tray.
Put a SilicA Gel pack inside (for any moisture).
Plugged in the ESC, Servo, etc... and filled the screw holes directly holding the radio tray down using "Ultra copper" gasket maker.

Once this was done, then i used the gasket maker along the seam of the top lid of the radio tray and put it in place and screwed it down. This is now 100% sealed internally!

as for the ESC, it already stated it was waterproof, but i still ran a bead along any suspicious areas using the ultra copper gasket maker.

All good to go now.

great thread, helped a lot !!
Here's what I've done, I went for water resistant instead of proof. No plans to dunk the thing, just mild maybe top of tire deep and splashing.

using a Traxxas waterproof servo and electronics put in a case I whipped up.



the lid leaves two small gaps on the rear corners, which I will leave for some cooling, just needs some sealer around the holes. and yeah, it's as cramped as it looks.

thanks for everyones input to the thread "thumbsup"

Here is a link to my thread on how I waterproofed my motor:


its a how to with pic's, hope it helps.:)

Life is good with the traxxas water proof set up.
I have had zero [porblems thus far"thumbsup".

liquid tape
is there any down fall to the liquid tape? How hard is it to remove?

808toys 07-09-2009 03:14 AM

i think traxxas has a water proof esc and i think the goat is water resistent

N.C. Scorpion 07-11-2009 03:04 PM

How easy is it for the srock w/k esc to cool in one of those project boxes

2500hdon37s 07-14-2009 04:15 PM

can you use petrolim jelly like the grease? and can you use just regular berring grease?

slackerman 07-23-2009 02:19 PM

Thanks for the info!:mrgreen:

i just drove my new losi mrc into water about 30 mins ago, now the reverse doesnt work, and suggestions?

shadowrejects 08-12-2009 10:06 PM

yes, the traxxis summit has a waterproof ESC and u can also buy a supply box from traxxas that it waterproof that ur ESC fits in

shadowrejects 08-12-2009 10:07 PM

i went thro 3 ESC's so far, on my MRC drivin in water up to the rims, im headin to my 4th, LOL

jwalker 08-12-2009 10:12 PM

i just filled up my electronics with electrical grease and have driven my crawler under 3 ft of muddy creek water and never had a problem. i like it better than putting a box on the chasis cause you can put your electronics anywhere you want without the restriction of a box that takes up space.

My rig just fell off the falls and into the water. It was fully submerged for 20 sec's. No worries, got it home and took an air hose to it. Note: If your rig is not set up to be water proof Attachment 109126

[ATTACH]109129 "DO NOT USE THE RADIO" while it is submerged. That is the key to possible survival.

plastidip or liquid tape
for the servos which is better: plastidip or the liquid electric tape/heat shrink stuff? ive seen where ppl are using both but wondering if one is better than the other. any downfalls, removal, etc...

How Waterproof Is Your Truck?
Here's how I waterproof mine.
My electronics configuration
1) LRP AI runner (its already a waterproof brushed ESC). so one item less to waterproof.
2) 2.4GHz Receiver - prefered as it has shorter ant and can simply hide inside a tupperware box. (in this case I used a lock and lock box.
3) 2 x extension connector lead to receiver.
i) 1pc extension for esc ii) 1pc extension lead for steering.
4) 1 x hightorque servo ERG-VX servo....already has good rubber ring all round the case, reinforce with sillicone sealant for extra protection. What you need is to put a rubber o-ring round the gear before you put in your servo saver or servo horn.
5) Alternatively use the Traxxas high torque 'WATERPROOF' servos. These servos are 100% waterproof at stock.

The trick is to seal the extension cables and NOT your orginal esc or steering servo connector cable!!!!. Route these extension cable to your 2.4 Ghz receiver instead!!!. Then hotglue the hole where these cable pass thru.


And last but not least mount your RX onto a sponge...the sponge is used to absorb water just in case a little water gets in. It will first get absorb by the sponge.

The above is the easiest and the most hasslefree way to maintain and transfer your electronics from one truck to the next!!!
And finally, TEST TEST TEST your little box in a little bowl of water before you put it in your truck.

And here's the vid of my CR-01

1 thing I have heard fron the boat guys is they remove thr RX from the plastic case and dip it in some liquid wax a couple times. I have never done this but it should work. They dont like to put their stuff in ballons because IF the water gets in it has no way to get out.

Just a thought
