The fly-ball actuator was introduced to R/C modelling in 1951 by Brayton Paul, [5] and consisted of an electric motor and a centrifugal governor connected to a free-running axis that could, with the motor running, pull a rudder control rod by varying degrees. Used with a keyed radio system, this allowed some control over the rudder position by ...
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.
The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...

- 1955 Ford Motor Company RC Model Car - Automobile manufacturer studios used scale models to reduce new design development lead times and save money. Among Ford designs executed in 3/8 size were the LaTosca, a futuristic bubble-top dream car, and the Mexico, an aerodynamic reskin of the 1955 Thunderbird that was designed to top 200 mph.
Of much less complexity are the types of RC jet aircraft that actually use an electric motor-driven ducted fan instead to power the aircraft. So called "EDF" models can be of much smaller size, and only need the same electronic speed controller and rechargeable battery technology as propeller-driven RC electric powered aircraft use.
Images of a glowplug engine and a "diesel" engine are shown below for comparison. The most obvious external difference is seen on top of the cylinder head. The glowplug engine's glow plug has a pinlike terminal for its center contact, which is an electrical connector for the glowplug.
1:10 scale radio-controlled car (Saab Sonett II)A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
