Understanding the basics of your radio control gear rc transmitter and rc receiver

Comprehending the basics of the remote control gear rc transmitter and rc receiver, and the ins and outs to create your rc plane do what you would like it to (more often than not!), is essential if you are to obtain the most from your brand-new hobby.

Incidentally this site was initially written prior to the creation of 2.4GHz (gigahertz) rc transmitters and receivers, therefore it mainly discusses the standard MHz (megahertz) remote control gear. However with that stated, the essential operating information is identical for types.

The fundamental components of the remote control system would be the transmitter, receiver and servos.

Battery power, or individual cells, are necessary to power all of the components. However, receivers and servos of contemporary electrical power (Air) rc airplanes seldom their very own battery power as their power is taken from the motor battery power via what is known as a BEC - more about that later.

Traditional MHz remote control systems were generally purchased like a complete set that incorporated the rc transmitter and rc receiver, 4 standard servos along with a charger - a good example is proven below, within this situation the Futaba T4YF...

However these days it's more prevalent to purchase only the rc transmitter and rc receiver, or maybe even the transmitter alone, with no servos. This is just because servo size and type varies a lot nowadays, as their applications are much more varied than in the past - it might be challenging for the maker to understand which kind of servo to set up this area, to date easier to leave the selection to the pilot!

Also, many mass-created aircraft (i.e. RTF, BNF & PNP type models) include servos (and receiver) already installed, therefore the buyer does not always need separate ones.
