I have the 3DR hexacopter PDB. Recently my hex went down when one of my motors stopped in flight. I thought it was a failure of the ESC. Turns out, the PDB must have shorted out because I am not getting any voltage to that ESC. Power to the other ESC's is fine. I am running 6S batteries and pulling about 27 amps average (about 43 amps max).
Has anyone else had this problem?
Is there a maximum rating for the PDB? I don't see one on the website.
