Hello,
I've recently assembled my 3d robotics hexacopter kit, and I'm trying now to calibrate the ESCs, which are 3d robotics brand. When I plug in my Lipo, they make the musical note and beep, and the propellers jerk slightly. And then the beeping continues indefinitely. Any advice about what I should do?
I tried setting the throttle at 50%, or powering on the APM with the USB, but neither of those things worked.
thanks

Most likely that is an error code indicating "bad/invalid pwm input" meaning the signal (or lack of signal) on that ESC is not in a valid range. Usually this is a bad connection from the APM to the ESC. Check the wires. Bypass the connection direct to the receiver as a test.
