The reason is that I will be useing a 12 vdc battary to run the motor on the RC boat and I would like to make a small ele. Circuit to give me the 6 vdc and use the 12 volt battary.

An LM7805 voltage regulator will do the job, but it may well be that your ESC has a BEC built in that will supply the RX and servo(s).
Historically, most RC gear has been designed to run off a nominal 6 volts, with the ability to function well down to a nominal 4.5, allowing for 4 dry cells or 4 rechargeable cells.  However, some modern accessory controllers use PICs and similar, some of which must only be used from a regulated 5 volts.
