Hi critter,

Most all CCD cameras are 5V anymore. Your receiver doesn’t regulate voltage, just passes the battery voltage or voltage from the ESC to the servos. Even if it's from an ESC, you may overtax it running a camera and servos. Fortunately, your starting voltage through a linear regulator @5V would be a perfect solution. The cameras really need clean, regulated voltage to produce a clean result. You likely don't want to share voltage with servos or other noisy items anyway.

Hope this helps,
Q

PS. CCD’s are just more expensive than CMOS.
