JR's analog servos boast every advantage of their digitized kin with the obvious exception of a digital amplifier. But don't let their "humble" analog circuitry fool you. Both have the composite, hard-coated metal gear train and both use the same dual ball bearing shaft support. They also use coreless motors that provide more than enough speed and torque for any competition level 1/10 car or truck. Even in larger scale applications like monster trucks and 1/8 on- or off-road vehicles, the Z4800T can handle just about anything the driver can dish out.
