I'm getting the 4 different sounding beeps on startup, after installing a new ESC. I read in a post that this is due to the ESC looking for an voltage cut-off value. Does anyone know the procedure in the DJI ESCs, to set the cut-off voltage? Easy enough to hook up the ESC to a fixed wing receiver/transmitter, make the changes, and return it to the Phantom after it's been set. Any ideas on this?
