Default What is a BEC and do I need one for the below combo?

I recently acquired a great planes rimfire 1.6 and castle hv 80 esc. I plan on using the combo for my 1/4 scale sap nieuport 17. What other electronics are required other than radio and servos? Do I need a BEC? Thank you.

A BEC is a Battery Eliminator Circuit

Its a component built into many ESC's that provides power on the positive lead of the throttle servo meaning small planes don't need a receiver battery along with a flight battery, it sends a regulated voltage to the receiver.

The HV-80 doesn't include an integrated BEC so your choices are to purchase a separate BEC and run the radio/servos from the motor battery, or, given the size we are talking, just run the receiver from a conventional receiver battery.
