The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
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 sailing, a boom is a spar (pole), along the foot of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. The primary action of the boom is to keep the foot flatter when the sail angle is away from the centerline of the boat. The boom also serves as an attachment point for more sophisticated control lines.
Many mast-aft rigs utilize a small mainsail and multiple staysails that can resemble some cutter rigs. A cutter is a single masted vessel, differentiated from a sloop either by the number of staysails, with a sloop having one and a cutter more than one, or by the position of the mast, with a cutter's mast being located between 50% and 70% of the way from the aft to the front of the sailplan ...

The winch is made of cable made up of a braided synthetic rope, or a steel cable wrapped around a motorized drum. Each is controlled electronically, allowing the operator to control the winch speed. [5] Modern vehicles typically use electric winches running off the car's 12V starter or 24V secondary battery. The winch is either controlled with ...
