I have just bought a BlackJack 26 from ebay. The motor looks like the original <font size="2" face="Verdana"><font size="2" face="Verdana">A3630-1500 Brushless Motor</font></font> but it has been upgraded with an 80A ESC, Octura 442 prop, and red alloy prop supports. There is only one deans connector so I think I can only plug in one battery.

What battery would you suggest is best for overall speed and reasonable endurance?

Also do I need to program the ESC? If so how!?

Thanks for your help as I am new to this so please dont be too technical on replies.
