An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking. Miniature electronic speed controls are used in electrically powered radio controlled models. Full-size electric vehicles also have systems to control the speed of ...
Novak Electronics, Inc. of Irvine, California was a manufacturer of radio control electronics.

A mass-produced radio-controlled yacht In 1898, Tesla demonstrated a radio-controlled boat (U.S. patent 613,809 —Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles). A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment.
The stationary (stator) windings of an outrunner motor are excited by conventional DC brushless motor controllers. A direct current (switched on and off at high frequency for voltage modulation) is typically passed through three or more non-adjacent windings together, and the group so energized is alternated electronically based upon rotor position feedback.
Radio-controlled boats are model boats controlled remotely with radio control equipment. The main types of RC boat are: scale models (12 inches (30 cm) – 144" (365 cm) in size), the sailing boat and the power boat. The latter is the more popular amongst toy grade models.
In 1989, Traxxas released its first radio-controlled boat, the Villan IV. In 1992, its first RTR nitro model, the Nitro Hawk, was released, followed by an RTR nitro boat, the Nitro Vee, four years later. [1] In 1999, Traxxas released its first full sized monster truck model, the T-Maxx. [1] A larger monster truck; the X-Maxx, came out in 2015. [3]
