The axon of a motor neuron divides just before it enters the muscle fibers and forms synapses near the nuclei of muscle fibers. These motor neurons are called somatic efferent neurons. Visceral efferent neurons form synapses with smooth muscle, cardiac muscle, and glands.
This is the electric powered, radio controlled, Tx-R (Transmitter Ready) Flyzone DHC-2 Beaver Select Scale Airplane. This is the Tx-R (Transmitter Ready) version that includes servos, an ESC and SLT receiver.
They are also used in powerful heavy-duty sail boats. Servos are rated for Speed and Torque. Normally there are two servos of the same kind, one geared towards speed (sacrificing torque), and the other towards torque (sacrificing speed). A good example of this is the HS-625MG servo and the HS-645MG servo.
