    esc went boom!

    I've had my e-revo for about 3 weeks now, I have had some much fun with this thing!

    In an unintentional back flip situation I broke

    1.) Drive Axel
    2.) Wing

    What my father in law broke in one miss hap with a fence post

    1.) Drive Axel
    2.) Upper and Lower A Arm
    3.) Suspension push rod

    He felt so bad he bought me replacement hopup parts for this car. RPM arms and axle carriers (front and back) and metal drive axels. He also promised never to drive it again ... lol.

    So after a bout 30 minutes of a run yesterday I took it in to my house to unhook the batteries and call it a day and as I was about to do so smoke starting pouring out of the ESC and a little mini fire ensued. I've attached the result. I have to note, there was no water involved and I was running ******* 65c 5000 mah lipo batteries (recommended to me on this forum).

    I did find a fellow on ebay with a replacement ESC for $80 which was a new pull from an e-revo, it's on it's way. I'm told castle is fairly good with warranty so I will be sending the baked one back to them to see what they say.

    My questions are :

    1.) I've read about a lot of these castle ESC's going up in smoke, are they that bad?
    2.) If I wanted a replacment ESC, somethign that will work with my castle brusheless motor... what is the best choice? Something that is maybe a little more rugged that wont blow up and make my wife acceptanec factor even less than it already is. Someone recommended the hobbywing xrun 150a or something, thoughts?

    Thanks again guys (also attached pics of my upgrades after the fence post incident)

    That's a shame but not uncommon for a castle esc to whoosh. They will replace it as it has a year warranty but expect it to take several weeks. Their after sales support isn't up to much.

    That's some good upgrades, watch the pop outs though with those cvds and tru tracks. Either get the extended cups or don't jump it too high.
    Signature removed due to excess awesomeness.

    Are you running 6S? Im running my truck on 4S and I've never had a problem with the ESC at all. I find the MMM ESC's to be quite good IMO. But since getting an ERBE and floating around this forum I've notice far more reports of failure. Im guessing its due to far more guys running 6S and pushing the truck hard than in the other places I see these ESC's.

    I have a XErun 150 amp in my 1/8 onroad car and its a very nice ESC. I don't think its on par with the MMM but nice, especially for the money ($100). The other route you can go is Tekin... but your going to pay for it.

    At this point I'll have 2 x castle mamba monster esc's (one in for warranty and the other in for repair). That would leave me 1 spare and both under warranty. I'll see how it goes with round 2.

    My Castle stopped working after 6 days......have a new setup on order from Castle, they have no problem warrantying, but ive been waiting for a month and a half. Got impatient after a month and put a Tekin RX 8 and T8 in, way better in my opinion. I've run 6s, 4s, and the stock batteries and haven't had a problem yet.

    Is that 65c per battery? and is that 2s or 3s.

    I run 30c 5000mah 3s batteries on my MMM with no issues and I have never had a hot ESC even though it has been coated in plasti dip as it rains a lot where I live.

    This info below I got off the brushless may help.

    ( mah x c rating / 1000 = amps)

    more amps the better / minimun of 120 amps.

    The ESC will only draw the amount of amps it needs.

    Higher the mAh the longer the runtime.
    For brushless systems 8000 mAh about 45 min & a 5000 mAh about 30 min.
    Times are longer for brushed systems.

    Batts in series double the voltage:
    2x 2s 20c 5000mah = 4s 20c 5000mah

    Batts in parallel double the mah capacity:
    2x 2s 20c 5000mah = 2s 20c 10,000mah.

    A temp gun is kind of a must have.....

    Hot motor + cool esc = under geared.
    Cool motor + hot esc = over geared
    Everything warm just right..

    Motor ~ 180/190*F (82/88*C) maximum, ideally 140/160*F (60/71*C), temps can be 10*F higher inside the motor
    ESC ~ pretty much same temps / Fan comes on @ 150*F (65*C)
    Lipo's ~ 140*F (60*C) max, ideally 100/120*F (38/49*C).........

    Besure to check sizing before you buy any batteries...

    In time some batteries will become discontinued...

    No particular order as to good, better, or best....


    With larger Lipo battery wires, you might need to - enlarge the exit hole on battery doors....
    or run wires out the vents..
