Electronic speed controllers (ESC's) electronically regulate the voltage output from the battery to the motor on a radio controlled model from the operator's inputs made on the throttle stick on the transmitter. For aircraft the speed controller will need to be lightweight and compact, and this is now very acheivable with micro electronics. Aircraft speed controllers have no need of the bulky heatsinks that car and boat speed controllers often have, as they are air cooled. There are two types of speed controller, for brushed, or brushless motors. The limit of the ESC is rated in amps, and is usually indicated in the name. Check the motor specifications for the continuous current rating, and match the ESC to that, maybe allowing a little extra amperage for safety. Most modern ESCs have an automatic cut out protection, but this is not foolproof, and so matching the ESC to the motor is important.

Jeti Electronic Speed Controller 150 (PJES150)
The latest generation of versatile, lightweight, Jes electronic speed controllers. With all
functions being microprocessor controlled, an automatic set-up of each unit to match any
transmitter is eliminating the need for manually adjusted potentiometers during the
installation process.
BEC Battery Eliminator Circuitry provides the receiver and servos with a 5 volt supply direct from the drive battery eliminating the need for a separate receiver battery. PCO Power Cut Off system gives a safety margin during the flight. As the drive battery voltage falls, the PCO checks the value and cuts off the motor at a point which leaves sufficient power to operate the receiver and servos for a reasonable period of time. It also provides a small margin of power for emergency motor operation during landing difficulties, for example. Current limiter each controller (except Jes 050) will tolerate 200% of the specified Continuous Current Rating for a period of 0.5 seconds. If this is exceeded, the controller automatically shuts off the power to the motor. This is particularly useful if the propeller is accidentally stopped whilst still at full power, during landings, for example.
