9 gm SG90 MICRO SERVO (analog)

The small and inexpensive 9gm SG90 servo performs very well with all of our models, and other lightweight RC models as well.  It has plastic gears and weighs approx. 10 gms including the wire and connector. It comes with three servo arms and mounting screws.   Please see the picture!

The servo case measures 27 mm tall, 23mm long, 12mm wide - not including the mounting lugs and the output gear. Including those, the overall measurements are 32.3mm long and 30mm high. The connector wire is 9 inches long.

The SG90 servo is capable of a 180-degree output by modifying the "pulse width" signal.  A standard operating servo has a pulse width of 1 to 2 msecs for 90 degrees.  To achieve 180 degrees of output, this parameter needs to be set to 0.5 to 2.5 msecs - which can be done on some sophisticated TX radios such as the Radiomaster.
