Steering Servo

[JoFreak]

Hm, let me see what I did...
digital (should be more precisely, especially with a good RC-system)
Hitec (HS-5955TG, no clue on the JR stuff though)
both (had torque in form of a HS-5645MG in the beginning, was to slow, made the truck handle like on marshmallow highway)
single (if the servo you get is strong enough, 2 servos never get you 2 times the performance)
no problem (have a DX3R)

obviously you should get one with metal gears
