The Castle CC25 will come with bullet connectors to connect it to the motor. To connect ESC to battery, I use Deans Ultra's, some like the Dean's mini's - and some like Anderson's - I'd pick whatever your buddies are using - makes it easier to creativly borrow batteries from them..
ESC to reciever will come with the ESC.
