I looked at the HobbyKing info on this plane, and it looks as if it's an ARF, so the pilot supplies the motor, esc, batteries, etc. So I'd think the connector would depend on where you buy the batteries. If you get a 1300-1700mah battery from HK, it'll probably come with an XT60 connector (the yellow 5-sided type). ESC's coming from HK usually come with the battery wires bare, and as CG mentioned, you'll have to do some soldering.
