I was playing by a creek today and flipped my crawler on its top in the water, i took it inside and imediatly started blow drying esc and reciver!(as manual said) i can turn the truck on and the wheels will go to nutral and the a red led light on the ESC comes on and makes a beep sound.. when i turn on my controler nothing happens!! no do ra mi or anything.. is my ESC out or is my reciver?? if so whats the best replacement?

do you have another radio/receiver you can try? most likely its the receive, but could be the bec in the esc fried and not sending power to the receiver

crawler_byrd44

no i dont have another one to try.. i just started gettig into this a couple weeks ago.. havent even had my crawler a full week yet . should i look into getting another ESC first? and if so what type? dont wanna spend all kinds of money on it but i want a good one to..

BTW nice builds u have man lookd like u know what ur talking about haha.

GREAT news! put my esc and rwciver in a bag of rice last night and now its working!!! woot woot

nitrosportsandrunner

cool
if you want to upgrade the ESC, buy a used traxxas waterproof XL-5. Ive got them for $25 shipped before on ebay.

crawler_byrd44

thats not bad at all.. i need water proof for sure! do i need to water proof my reciver also?

could just get a traxxas receiver box I find them usually pretty cheap on ebay, and just ziptie it somewhere.
Like on my one RC I ziptied it to a rail on the side.

nitrosportsandrunner

yes, and the easiest way is a baggy or ballon over the reciever. Its best to put a dab of grease where the wires come out with a zip tie holding it closed.

didnt think about the rice thing, i saved my sons cell phone awhile back with a bowl of rice

you can de case the esc and rx. then paint em with liquid electric tape.
the xl5 could be your best bet. what tune are the motors?
the only problem with home waterproofing is theres only one way to test it

crawler_byrd44

Gotta love rice haha, it has 2 540 high tourge motors, water could get in them ez to should i worry about them? and im def gonn do the balloon trick on the recivr! but the electric tape paint seams like the best for the esc to me.. thanks alot guys this stuff really helped!

The Mad Modder

Brushed electrical motors are one of the few pieces of electronics that are very resistant to water. That said, I would use one of those electric motor filters to keep dirt and debris(which can shorten the life of the motor) out.


Not sure if it would fit in with your setup, but you could get an electronics box to put them in and just seal the box.

ESC I find a tad trickier as you have to make sure the FET's still conduct heat to the heatsink, but you got a good seal around the conductive parts that can short.

as for the radio like I said easiest way I know to be 100% sure it ain't gonna get wet is a cheap traxxas radio box like the one on the stampede 4X4 as it has the screw holes to mount it on the outside(the slash 4X4's box has holes in the box itself and would let water in) which could use zipties to hold it to a chassis rail.

Ive done the ESC waterproofing on my 6wd WK with the traxxas RX box ziptied to it last year for winter running, and after the run I just hose the RC off to get the salt from the street, and snow off. The RC's worked perfectly fine.

My SCX10 also uses a traxxas waterproof box (mounted where the stock radio box goes with a few mods) with a XL-5 ESC that I had laying around.

KID_EVIL!

There is a guy on youtube that shows how to waterproof pretty much anything. it's worth the bother to take a look. squirrelrod is his name. check this out......[link=http://www.youtube.com/watch?v=yMYCEJWgUZA]ESC[/link]
