Hi,
I've seen the jDrones 20A ESC has low voltage cutoff.
when i think of that - this will cause instant motor stopping, and immediate drop of the arducopter,
no ?
Is there any way to cancel that feature ? so that i could land my arducopter safely even at 2.9v per cell ?

It might be that your main flightelectronics will reboot before ESC's are hitting voltage cutoff. Besides you should never go below 3 volt/cell due this will murder your LiPo batteries. As ArduCopter and all this type VTOL machines are relying on steady input voltage, when closing cutoff areas power supplies tend to start fluxuating. This fluxuating will cause gyros/accelerometers etc to behave weird which usually means flip landing or similar... not so unwanted lading.
On airplanes you can push your batteries to their limits but it is not wise to do so with helicopters and especially not with multirotors.
Soft Cut-off / Medium are default.
