Description

JR MP91R WIDE-VOLTAGE BRUSHLESS RETRACT SERVO

Overview

JR - JRPSMP91R - MP91R Wide-Voltage Brushless Retract 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 low-profile 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° of travel and zero deadband. A durable composite-metal gear train composed of hard-anodized aluminum and hardened steel and brass gears provides backlash-free operation.

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 that the servo returns to the neutral position very slowly. The benefit is that youll see longer life from the internal servo gears and less wear and tear on the linkages of the control surfaces.

The MP91R retract servo features a proportional output so you can set the servo endpoints via the travel adjust function of your transmitter, making mechanical retract setup simple and accurate. One-hundred-fifty percent in transmitter travel adjust equals 180 degrees of servo travel.

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