My e-revo brushless edition build

[Chadworkz]

My Dad absolutely loves the Bug body on your son's E-Revo, and wants one for his E-Revo, he just has to come up with a paint-scheme for it so I can paint it.

Anyway, you got it looking great, MC!

Well not always but sometimes, the things I do are just plain stupid. I wanted to give this ESC waterproofing thing a try so I started coating the ESC board with this liquid electrical tape stuff. I was going well but once it dryed, it was not stuck that well on the board and I was thinking that if it gets unstuck a little bit along the heat sink for example, then there would be a place for water to get in and it would get trapped in there and never dry off. Plus I was not convinced that it was that water tight, especially behind the caps where it is a very tight spot and I couldn't positively verify that the stuff got in there to seal the whole board properly. So I ripped the whole thing off the board and started thinking of what else I could try. I had this tube of white silicon for outdoor windows and doors. I put a small tip on it to squeeze silicon in tight spots and started working on sealing the board. I thought white is great because I could really see where the silicon was going and really check that it was finding its way everywhere. It went well and once I was done, it looked like the board was completely sealed. Then I glanced at the tube and saw:

LATEX WATER BASED

I couldn't believe what I just did. I just coated everything with a water based paste So I thought to just let it dry and once the water is out then it'll be fine. Three days later, the thing is still not dry. I decided to clean this stuff off the board but how? I did something radical. I let the board soak in warm soapy water for 9/10 hours and that dissolved the latex based silicon and I was able to clean the residue with an old tooth brush. I got everything off, the board was really clean. Too clean! That protective coating from the factory was off also. So after cleaning everything to like new condition, drying it with compressed air and letting sit on a furnace register for two days, I plugged the board back on the truck with a couple Turnigys and flicked the switch on. The ESC was working like nothing happened

But I wanted to get a protective coating back on the board so Tremclad Urethane Clear Coat to the rescue. I used this stuff on many surfaces and it sticks to just about anything, dries quickly and is really though once dried. I gave the board three coats. I actually think that it is practically waterproof now but I'm too scared to dip the ESC in water to test it.

I am not going to try it, I don't want to come here again and write another lengthy post explaining how much of an idiot I am again
Water ''resistant'' is enough for me.

I thought I'd try this clear coat stuff on my steering servo. It is supposed to be water proof but it has proven other wise in the past so I gave the servo three thick coats of this stuff. I plan on running my ERBE in the snow again tomorrow and I will see if water will stay out of this servo from now on.



I also got a shower cap to try out. I read about this trick to keep water off the electronics. I was disappointed that there were no pink ones with pretty flowers. The results are not that encouraging. Although it kept most of the snow, slush and water off the center of the truck where the ESC, motor and tranny are, it did let in some moisture. So I would say that this does help making the truck water resistant but not waterproof. But I did run through very slushy stuff and through deep puddles. Also, the cap didn't last very long, it got ripped in a couple places.



I wrapped my Turnigys in urathane gloves. I cut the tip of the index and ran the wires through it and zip tied both ends of the glove as tight as I could. Surprisingly, water got inside. Is it water or just condensation from the heat of the battery with snow stuck right outside the glove? From the amount of water, I would say it just got in.



One last thing about the shower cap, although it is only 30 degrees outside, the motor and ESC were much warmer then when I run without the cap. A thirty degree difference.
