    ESC Smoke Show

    well my stock esc ezrun 80 amp in my earthquake 8e, after water proofing it about 7-8 packs ago went up in smoke. Opened it up and it had water in it. Looking for a waterproof esc. any suggestions, would like it to be hobbywing because i already have the programmer. Looking at this model,Hobbywing EZRUN WP SC8 Waterproof 120A Brushless ESC Speed Controller Truck. Will this work with the redcat earthquake 8e?

    RE: ESC Smoke Show

    I'm sure that should work fine, considering its a 1/8 scale ESC. Also has a higher amp rating which is always good.

    RE: ESC Smoke Show

    agreed, based on the specs it should work just fine.

    how did you try to waterproof the old one? If water got in then something didnt get sealed right. Sucks, sorry to here about it.

    RE: ESC Smoke Show

    i used liquid electrical tape and coated the whole circuit board, but this new design 80 amp ezrun has 2 boards stacked together on top of each other with about 1/4" between them...hard to get it all sealed properly between the heat sink and circuit board.  I just did it to try it out...i don't mind spending only  for a factory sealed waterproof unit, there is video of this thing submerged and still working.  I'm pretty sure it will work from the info on the specs, just wondering if anyone has actually installed one in there own truck.  Thanks

    RE: ESC Smoke Show

    Ricks, I have never tried to waterproof with the liquid tape but I did build a little waterproof box for the receiver and esc and all connections with a Plano waterproof box. Just a suggestion. I wet my receiver once and that was enough for me. The box was 7 bucks and I never wet either one again. I'm in Louisiana so there is unexpected water everwhere...waterproof is a must have for bashing down south...

    thats not a bad setup.

    would be harder on a 8e, as there is less spare room....and the ESC is higher amp/volts and needs more air for cooling. That kind of setup on a 8e could only work safetly in the winter time.

    But the sc8 should do the trick. Then build a box like john's for the reciever and seal your servo's case with elect tape and add some grease to the output and you are good to go.

    RE: ESC Smoke Show

    Agreed, I do sometimes experience the overheating ESC but the truck stops with proctection and starts again once operating temp is reached. When I'm running in a known dry zone I just pop the box top off and overheat is not a problem. It was a quick fix for known wet situations. I would like to order a waterproof esc and servo as well, but funding is a hurdle. Once I get one I'll reduce box size for receiver only.

    Let us know how the new ESC works. I may get the same for my Volcano.

    RE: ESC Smoke Show

    update.... Well put the new hobbywing 120 amp sc8 waterproof esc in the earthquake 8e, ran 2 packs though in the snow and this thing is great. The sc8 is much smaller than the 80 amp and it crawls at low speeds better also. (no ratcheting at all) I wish the earthquake came with this esc. I just hope the smaller size will stay cool enough in the summer.
