Recently i was bench testing my HexRotor during which i drained the Lipo battery. During the bench testing, when the 3S 6Ah nano tech lipo level reached at around 8 Volts (as shown on the mission planner via Xbee) the motor stopped. I dropped the throttle to zero and then again increased the throttle, the motor started moving again. After a while they again stopped. I plugged out the Lipo and stopped with the testing
The next time i plugged in my Lipo, motors (3 and sometimes more) started twitching and giving a continuous beep ( i think with an interval of 0.25 sec, but continuous). I calibrated the ESCs again. But when i try to arm and fly, only 5 out of 6 motors move and the remaining one (the first motor i.e right side on hexa X) starts giving the continuous beep. Any ideas what might be the problem?

Is your LiPo still OK? It shouldn't be run down to any less than 3.3V per cell = 9.9v for a 3S. Going below that can cause irreversible damage. Does it look bloated at all?
I am using jdrones ESC 30 A. The manual says such a beep is due to " throttle stick not at bottom position". But even at bottom throttle position, same beep is there.
