I just ran the numbers* and the 553 oz-in servo you want to use is likely illegal due to rule R48-L (depending on what its maximum rotational speed is, as it will likely have a peak power output over the 4W at 6V limit).

* Assuming max torque is 553 oz-in and the max rotational speed is .21 sec/60 degree (which seems to be the average speed I found when looking up high torque servos in the 400-600 oz-in range at 6V), this results in a peak power output of 4.86 Watts.
