VEX controllers & Servos Voltage question

We have both some VEX controllers (Cortex) as well as standard futaba (5V servos). We would like to use them together.

The issue is that I think the motor ports on the Vex controller have 7.2 V outputs. I think this because all the VEX COTS motors are rated at 7.2V. This seems too high for a standard servo. I was considering using a L7805 voltage regulator on the power pin of the VEX output, I am also wondering if I would need a voltage regulator on the signal/PWM pin from the Cortex as well, or if it would be okay to leave as is.
