The MG91 is a nice small RC servo ideal for projects where size and weight are important.
RC servos are hobbyist remote control servos typically used in radio-controlled models, where they provide actuation for various mechanical systems such as the steering of a car, the flaps on a plane, or the rudder of a boat. These servos are not industrial grade and are not recommended for continuous heavy use.
This servo has slightly more torque than the previous revision. Also, unlike the MG90 the MG91 does not have mechanical stops meaning that an unpowered motor can rotate continuously in either direction but with a single rotation pot, will always snap to the same range when power is reapplied.
ConnectionThis servo can be controlled by an RC servo controller. You can find a list of suitable controllers on the Connection & Compatibility tab.
The MG91 comes with 3 servo rudder pieces and 1 set of screws.
