JR - JRPSMP82S2 - MP82S MK II Wide-Voltage Brushless Speed Servo

A variety of receiver batteries are available on the model market. With certain batteries, the modeler must carefully choose appropriate servos or use a regulator between the battery and receiver; otherwise servos may be damaged due to a high voltage supply. Now the JR brand has an answer with the new wide-voltage (WV) series servos. Every WV servo has a micro computer to detect incoming voltage and automatically set the right voltage for the motor.

JR wide-voltage digital servos are an excellent choice for an airplane's aileron or as the steering servo for a car. The extreme accuracy of JR digital precision gives a resolution of 5900 steps per 120 degree of travel and zero deadband. The torque and speed versions feature a durable super steel gear train, providing a longer life cycle and the ultimate level of durability. The gyro version employs nylon gears for unsurpassed accuracy.


Another sophisticated benefit of the new wide-voltage servos is the Slow Start function. When your system is switched on, instead of the servos instantly finding center as quickly as possible, Slow Start assures that on initial power up the servo returns to the neutral position very slowly. The benefit is that you'll see longer life from the internal servo gears and less wear and tear on the linkages of the control surfaces.

The motor used in this series of servos is a low-maintenance brushless motor that ensures long life and near instantaneous response. You'll feel the difference the moment you take off on your first flight.


Not recommended for use in non XBus applications where an extension of more than 48" is required
