DS8711 is air servo but internals should be same with Z9100T. different software most likely to adapt Z9100T for car use

I've had the JR9000T and JR9100T, never noticed a difference between them torque wise, both great servos that'll move big tires on big truck no problem.
The JR DS8711 is an air servo and the main difference between it and the JR9100T is the gears. Both are metal gears, but the contact patch between the gears is wider on the JR9100T. Why, air servos see more constant loads, instead of the shock loads a steering servo sees when going over rough terrain. Combine a tight servo saver on rough terrain and the JR9100T will hold up better than the DS8711.
