I did the Esc calibration as usual (Escs connected directly to the receiver), and the motors seem to spin normally after armed, but the strange thing is that I never hear the “6 beeps” indicating that is a 6 Lipo cell.
Same behaviour when they are connected to Pixhawk.
The escs are Hobbywing X-rotor 40A.
Is that normal? How can I calibrate them to hear the “Lipo number cells” Beeps?
