Wife burned up my Mamba Max on 5S over the holiday... :(

[Finnster]

Well it finally happened, the MMax went down on 5S lipos in less than 10 secs in my wife's hands.:007: :036:

To her credit I'm teasing a bit, tho it really was like 10 secs. I had been driving all over the TG holiday and the BL Revo was my last truck standing out of 3. Crawling over lumber, high speed street and grass runs, some yard racing vs my bro in laws stock rustler (yet he still won alot :mad:1 :005:, small track and tight turns, lots of me going too fast, wheels falling off, or breaking stuff :) .)

So she says "I want a to drive it, I want to do a race"
-"Ok dear, just be very, very careful. It has alot of power, just be easy on the throttle until you get used to it. It can get away on you really fast."
"Alright, I'll be careful"

1...2...3..go!

Up the hill it goes, drives into the tree which is turn 1. She hits reverse to back up, then tries to go forward, then I hear a grinding sound.
-"Woah woah woah, stop!" (thinking its the spur or diffs) then I hear the esc making the start up beeps. Uhoh.

Run over and I smell smoke. Don't see any, but unplug everything and look at it. Plug just the 2S batt in, red led comes on, but esc won't arm or beep. Looks like a FET may be burned, but hard to tell.

Either way the stock Rusty won the race again...

She didn't do anything I hadn't done many times w/ the truck. A stick was kinda stuck in the wheel, so its possible the rotor may have been locked and the amp surge killed it. Its supposed to have protection for that, but I doubt its perfect, and 5S may have been to close to the margins anyway for the esc to have a good chance of shutting itself down in time. Aw damn.

Guess its time to send her in (edit: the esc, not the wife, she's non-refundable ;) ). I'll prolly still run it carefully on 5s when I get it back, but its almost too much power anyway (if that exists. 0_o )The only time I can go WOT is on the street on straight aways, but everywhere else its a bit nutty. 4S would be just fine, tho I am waiting for the MMonsterMax to come out, and def looking to upgrade to that for more safety on 5s.

Perhaps I'll upload a really short vid of one of the races someone cought on the digi cam. Its pretty funny putting the 1500W BL 4wd Revo versus the 100W stock Rusty, however slow and steady often wins the race (and brakes far fewer parts.)
