The power triple lock connectors offer three levels of housing materials with keying and color code to prevent mis-mating on the assembly line. When presented with 2.0 ms input signal, the motor runs at full speed. A 1.5 ms pulse-width input signal drives the motor at approximately half-speed. When supplied with a 1 ms width pulse at 50 Hz, the ESC responds by turning off the DC motor attached to its output. The ESC generally accepts a nominal 50 Hz PWM servo input signal whose pulse width varies from 1 ms to 2 ms.

The DC ESCs in the broader sense are PWM controllers for electric motors. It also allows much smoother and more precise variation of motor speed in a far more efficient manner than the mechanical type. The rapid switching of the transistors is what causes the motor itself to emit its characteristic high-pitched whine, especially noticeable at lower speeds. Regardless of the type used, an ESC interprets control information not as mechanical motion as would be the case of a servo, but rather in a way that varies the switching rate of a network of field effect transistors. The device specially uses the TE Connectivity's Power Triple Lock System that ensures a strong connection between the ESC and the motor considering that RC plane needs good internal connection to avoid loss of communication during a flight. This device can be a stand-alone unit which plugs into the receiver's throttle control channel or incorporated into the receiver itself. It essentially provides an electronically generated electric power for the motor. This radio controlled aircraft basically needs electronic speed controller to vary the electric motor's speed as well as its direction. An aerial control is nothing new to us in which there are several technologies that are being developed to optimize its capabilities.
