Exclusive software developed by Spektrum for surface RC transmitters that includes all programming functions and features.

An important aspect of RC flying success, the Range Check is a ground procedure to test the radio signal from your RC transmitter to the receiver to make sure it is stron...

Returning your finished model back into a kit, often due to a crash.

The part of the radio system that converts signals sent by the transmitter into electrical impulses.

A device mounted into an RC car or aircraft that receives and decodes a signal sent by a transmitter. Servos, ESC, and other devices are plugged into the receiver.

A water/ chemical resistance coating that is applied to the PC (electric) boards that make the electronics highly water resistant.

An auxiliary receiver that works in conjunction with a main receiver. These are beneficial in larger aircraft and aircraft that may have Radio Frequency blind spots cause...

The transmission “scheme” that each specific radio manufacturer designs for the brand.

Refers to the incremental step size of the data transmitted to the receiver.

The vibration frequency of rotating or moving parts. Excessive resonance can cause vibration damage.

Short for retractable landing gear. Wheels and struts that fold up into the airplane to get them out of the air stream and present less resistance to the airflow.

Radio Frequency Interference.

The internal, vertical portion of the wing that gives it an airfoil-shaped contour.

The airplane axis controlled by the ailerons. Roll is illustrated by holding the airplane by the nose and tail. Dropping either wingtip is the roll movement. This is used...

Applying rudder alone can cause the aircraft to bank into a turn without aileron input. The ability of the rudder to perform a banked turn is called roll coupling since t...

Ready-to-Fly. Some newer airplanes are now available as RTF models. These planes usually come with everything needed for flight--plane, radio system, engine, and all hard...

The vertical control surface that controls yaw.

Abbreviation for receiver.
