Your welcome mate
As RC said look for an ESC with a "Bec".
The first esc I ever got was a mystery 100a esc without Bec and not knowing what a Bec was for I went ahead and connected it all up only to find that I had no control and the motor was beeping giving the "I have no control signal" beep. I then descovered that the RX had no 5v so I soldered in a LM7805 voltage regulator in to power the RX and servos. You won't hurt anything by not having a Bec it's just that it won't work without the 5v needed to fire it up.
