The MPH83TWV is a very impressive servo, extreme torque and a reasonably high speed, it has been designed for use with aerobatic aircraft and helicopters but is also great for many other uses where a high spec servo is required.
The repetitive motion of a servo whilst in use places a large burden on each component. The recent development of brushless motors has increased the product life of servo motors dramatically, however, when determining servo position using existing potentiometers, long-period use causes wear inside the potentiometer parts so that smooth linear operation becomes impossible. To address this issue JR has developed a new type of servo with non-contact position detection using Linear Hall ICs, which enable position detection using magnetic force. Using this technology, JR has now perfected its next generation of MPH Series Linear Hall Sensing Servos.
A variety of receiver batteries are available on the model market. With certain batteries, the modeller 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. Every WV servo has a micro computer to detect incoming voltage and automatically set the correct voltage for the motor. 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 centre as quickly as possible, Slow Start assures on initial power up that 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.
Whenever the utmost accuracy is your aim, the JR Linear Hall Sensor servo will meet your needs.
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.

About Servos Manufactured by JR Propo:
If used on a large control surface - typically aileron, rudder, elevator or flap on an Airplane. Digital Servos (DS / MP / MPH series) may move slightly around centre while on the ground, this is normal and will not occur in flight.
