I have the same buggy and run the Airtronics 94358 in mine. Tons of torque, 200oz @ 6.0volts. No doubt that it moves the wheels around, but I find I do pay a penalty with decreased battery run time. You may want to get a slightly faster servo than this one, with still a decent amount of torque. After all, I don't need this much torque, but i want this much torque.
