I just wanted to put this out there cause there seems to be no answers anywhere on it. This esc has a standard output voltage of 5.5v and it can't be changed unless of course you by a BEC. All other setting can be changed with a field card. I'm not putting this esc down at all because it is awesome with my motrolfly 2810-1000. I just simply wanted to let everyone know incase your thinking of buying it and can't find that spec.
