Default retract servos

Can anyone give me some torque ratings on common retract servos? I am using the Hi-Tech HS-75 in our Hangar 9 Corsair, and it doesn't seem to have enough power to reliably cycle the gear. My main question is, does the Futaba retract servo have more torque. It is rated at 92 in-ounces in the Tower catalogue, but I can't find a rating for the Hi-Tech servo. They are both rated for 4.8 volts only so I guess the easy fix of going to 6 volts is out. We are using a new 1500 mah 4.8 volt battery in this plane.

Thanks from old bird.
