MMM Explodes into FLAMES!

Yea it was crazy. I just got it out of the car, connected the battery, turned it on, it made all the right noises, then when I pushed the throttle on, it cogged a bit, then started smoking, then snap crackle pop! A little fire shot out of it.
I disconnected the battery before even thinking about it, and my mate just started ripping the wires out of it. The wires ended up about 10 feet away!

Just turning it on, then 5 secs later turning it off, it shouldn't of even started to warm the battery, but even after 5 minutes, when we came back after searching for the wires, it was warm to the touch. Must of drawn some serious amperage!

When I took it out for a run the day before it ran perfectly, then the last bit before I went home it was cogging something severely. Took it home expecting to find some rocks caught in the transmission but nothing at all.

you must have had 2 of thoes packs wired in parellel right?


and as for the vast magority of 6s setups going bacg, yeah i guess it is pushing the envolope.
i run/race with 6s in my revo.
never had an issue but my setup isnt crazy either...not even trying to get speed runs.
geared 16/68 on a 3905 tranny and that equades to 40mph on std MTR tyres.
it just seems that people see 6s, and steriotypicaly assume it's ultimate speed and power with no drawbacks.

MABEY there should be a note in hte manual stating that 6s operation is recomended for advanced users only.

You cooked and de-magged your motor, then the next time you used it > cooked esc.

Unless the motor wasnt hot after the last run, temps?
