No the eagle tree registration, is for the first pack, the second discharge i dont use eagle and the quark dead

for the quark not shutting off.. like jhautz said..
there's a place to set the voltage cutoff, and then there's a place to actually ENABLE the cutoff. is it possible that you had set the cutoff, but not actually enabled it?

Sounds logical to me!

mmmm its possible...
boys i open the esc and i see two component smoke...
One resistence and one diode(i suppose), in the zone marked "BEC"

That's what i thought. Try a seperate battery pack or a ubec. perhaps it works.

But because the steerin servo works with internal bec????

Don't know. might be that it's feeding back power but uses another powersource to juice the esc.

Come on, Virusss, just use a receiver pack and let us know.

nothing not work... :(

You have another controller?

No Captain i dont have another esc,what advised to me, quark or Mambamax?
I would buy the Mamba

You COULD test the mamba.

But with the quark 125 you are playing safe.
