Failing ESC
« on: February 12, 2017, 02:44:27 pm »
Hi Everyone,
 I crashed my quad a few days ago and afterwards when throttling up it would dip back and to the left.
 I thought it was the motor so I ordered a new set. Turns out it was an ESC.
After installing 4 new motors (which BTW sucked because of the coating they put on the wires...soldering to them and all) It still dipped back and to the left.
 So I went through and re-set the timing of all ESCs, re-set the control frequency of all ESCs but did not re-set the start force. It didn't seem pertinent.
Still had the same issue.
Soooooo...I switched out the esc and re set everything AGAIN...lol. and it no longer acts in the previous manor.
 Which leads me to my question...do ESCs go bad slowly? or all at once.
Also...since replacing the new ESC the motor that it controls starts way before the others. The other 3 motors start at around 1060 and this motor starts at around 1030.
Is this a problem?
Thanks in advance,
Que.

I think I have seen cases where an ESC lost it's calibration.  I can imagine this happening in a crash with a large current surge and voltage spikes.

I would put the "bad" ESC back on the quad and run an ESC calibration and neutral setting and see if that fixes it.
