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.
