esc waterproofing

did several searches (here, RCU, google, yahoo, etc...) and this what i came up with as the best solution.

a couple of months ago i thought i saw an article that was specifically aimed at the ESC that used the same method but i can't find it again.

do you think this will work on an esc as well? or do you think it will hinder the cooling process?

I dont know if it will work as good on a esc, but for the rx it will work nice, and i will go ahead and do that to my rx this weekend.

For my esc i use a special silicone grease, same as i used when i was into watercooling etc on my computers, and it do work like a charm, and will not slow down or make any negative effect on the heat displacement in the esc.
I would recommend using the silicone grease in the esc, not the rx though, but i think the right epoxy will also work.

As they said on that page, a baloon is not a watertight thing, and you will have condens inside, and you dont want that. And then you have to get them out and in the baloon everytime, and a baloon will NOT work on a esc.. but i guess most know that already
A watertight box is a nice thing to do for rx and esc, but filling the esc and rx with the silicone grease and or epoxy will probably be the best thing, and you can be more relaxed

yeah i'm not about to stuff an esc in a balloon. i know that could get messy if the ESC overheats for any reason.

my next thought, after a little searching in the box of maxx parts i have was to use the RX box for my ESC. i was thinking i could use tape to stick the esc to the inside of the box (the MC330 i am using is small). small enough i think i can stick it to the side and be able to keep it up off the bottom plate of the box some. by doing this if any moisture does get in the box my esc won't just be sitting in it but will be floating above it a little. but i could still pull the box easily to check

would a fan modifacation have to be done to the box? i've read most people do not have heat issues because of the slow pace of these trucks. i know it's hard to tell, but just in case anyone has done this exact trick before.

It's a good idea if you are planning on running trough water and wet places to use a plastic watertight box for rx and esc. And inside the box it's nice if you can use a good double sticker tape, and raise them abit from the floor of the box, but still it is a good idea to seal both rx and esc anyways, because the moist can still get there... just a thought so you will be more close to 100% sure that your equipment will hold up ;-)

I havent done that box thing yet, so i cant speak from experience, but im planning to do it cause im going to do mainly truck trial stuff and that involves water and mud etc, so it sould be for the best to keep it all in a watertight box.

For cooling, i dont think you have to worry about the cooling inside the box, it will most likely be ok and not get much hotter, if any hotter then it would sitting free outside the box... not for these slowspeed motors mainly used in crawling, and other faster moters that are geared down heavy, in the end.. both those setup's will run pretty cool, so i dont think you have to worry.
If you are worried, put a little fan on your esc, but i really dont think you will have to.

Hope this helps you out some.

very excellent. thanx.

i am just about to be finished with the project. i should be able to post up some pics soon. kinda waiting on the integy motor i ordered and i still have to make the motor mount after that. won it off EBAY last week. i would think it should be here soon.

most of my project was built from the search button. just to let everyone know HOW USEFULL that little feature is. ya know when you use it.....

this is what i came up with. stuck the ESC to the top of the box in one corner. gives about 1/4 to 3/8" of air around the unit
