|  Liquid tape + esc = no work????
Ok, so i have a tazer esc that worked fine when i got it. Took it apart and covered the inside with liquid electrial tape. (found a how to on youtube and did it just like that) Hooked up the esc to everything on the lr3 project last night, and nothing. No lights, no servor noise, no nothing. My question is this, can you destroy your esc if you coat it with this elec. liquid tape?

We are dealing with this liquid tape at work right now... Kinda sucks! I'm guessing while its wet it's still conductive. It the top was "dry" but the part in contact with the board was still curing when it was powered on, it could have been shorting. We use it to cover bulkhead connections, I don't think it's supposed to be used as a circuit epoxy..

those traxxas reciever boxes from the summit/slash are like 8 bucks... work great and no fuss... only slightly larger then the receiver... use that instead

at about 4:30 is where he states to use the liquid tape. And i guess i DID answer my own questions...lol. Quote:
Note to self, only use liquid tape to coat things that ARENT conductive....lol lesson learned and now a new waterproof esc is in my buying future:? | ||

Is there a specific epoxy one should use on circuit boards or will any regular 5 minute epoxy suffice? I wasn't thinking of water proofing, but more like reducing the potential for damage should say, the receiver got soaked.

You want conformal coating. like this http://www.crazypc.com/products/conf...ng-934900.html or this http://www.mcmelectronics.com/produc...LAID=220229316 |

At work we use a comformal coat that cures under UV light. The amount we flood it with, it cures in 45secs. To keep it thin and flowing in the robots, the carrier chemicals are conductive until they set under UV. I have waterproofed 2rx's and an ESC so far that are still running. I also have used a very flammable form of comformal coat on Strain Gages that need to be weather-proof. It is Polyurethane, that is 75% carrier chemicals that are flammable. Air Drys in 20mins, but does not Cure for 6-7 days. They do not recommend activating the gages until then. | |

Here is another link to intro conformal coating. There are different types. I think Silicone would be the best because it would allow flexibility where the wires stick out, and it's non-destructive removal may come it handy one day... http://www.electronics-project-desig...alCoating.html | |

I've covered boards in Liquid tape before and it worked fine. I just made sure it dried over night first. The Cap Lights I take apart and use for rock lights have exposed boards. I cover them with it and they work great.....Like it was said above, bet it was still wet when you powered it up. Pull it off and see if the ESC will still work....never know!
