I am experiencing a problem with my quad I have not had before.
I calibrate the ESC's (Turnigy plush 25A) works good both when I do it manually and automatically and they all spin at the same rate. When I plug the battery in again after doing the calibration They all start beeping constantly.
I don't know what is the problem, I have tried starting the APM 2 first from the usb and than plugging in the lipos to the ESC's.
I have used this setup before, only made minor changes to the arrangement of the components and uploaded the newest firmware and now it does'nt work.
Could someone tell me what might be wrong?
