FIRST lists in the manual that each sidecar PWM output has a max of 15 mA of current. You can go to this link to see for yourself on Page 30.

I could not find an amp rating on the HiTec servos, only voltage and speed on the HiTech site. You can call HiTec at 858-748-6948 and speak to their tech dept on feasability and specs. The drawings of the sidecar outputs show one servo per PWM. Remember running amperage will be much lower than stall amperage, which is what will cause you problems (aka blown) in the circuit.
