arga firmansyah replied to Virgil's discussion PIWHAWK and AERO SKY QUADCOPTER in PIXHAWK
"That beep sound indicate a battery failsafe, if you are using a fully charge lipo, then you must be set the battery treshholed level too low. Your quad seems to be twitchy, i think you should tune your pid, an autotune is working great."
