SAFE technology is an advanced flight assistance system that gives pilots the ability to fly without the worry of crashing due to common mistakes such as orientation loss...

A resequencing of the data the radio transmits based on the type of mixing you select. This feature helps to sync control services that are connected (such as a swash pla...

An electromagnetic device that moves the control surfaces and is controlled by the electrical impulses from the receiver.

The removable arm or wheel which bolts to the output shaft of a servo and connects to the pushrod.

This radio feature allows you to install the servos where they can give the best pushrod routing without concern about the direction of servo rotation. When your installa...

A biplane having one wing significantly smaller than the other.

A high-lift device on the leading edge of a wing designed to keep air flowing over the wing at a higher angle of attack than could be achieved otherwise.

A maneuver where the airplane's controls are used to make the fuselage fly at an angle to the line of flight. This causes a tremendous increase in drag and allows an...

Unwanted, excessive free movement in a control system. Often caused by a hole in a servo arm or control horn that is too big for the pushrod wire or clevis pin. This cond...

Model rolls at a uniform rate through one (1) revolution in either direction. Center is the inverted portion of maneuver. Inside Loop: Model pulls up and executes the loo...

Designed and developed by Spektrum, Smart Technology employs the latest advancements in connectivity and integration for a hassle-free and more fun RC experience. This is...

A type of rolling maneuver that is very quick and violent. It's basically a spin where the flight path is in any direction chosen by the pilot.

Your first totally unassisted flight that results in a controlled landing.

Large panels that fold out of the aircraft structure to provide a lot of extra drag to the air. They are not part of the wing structure, but are usually mounted on the fu...

Cone on the front of the propeller made from plastic or metal to improve aerodynamics, looks, and use of an electric starter.

Model performs one-half (1/2) roll in level flight then immediately executes one-half inside loop to level flight in opposite direction as entry. (This is basically an Im...

Basically a reverse Immelmann. The airplane rolls onto its back, and then the nose comes down to finish a 1/2-loop. The direction of flight is changed 180°.

A model which possesses some attributes of many of the specialty airplanes and is best for general flying as they are the most versatile and durable.

(Slang courtesy of RC Universe) A new Nitro owner running his engine too rich, causing all the excess fuel to either run down the fuselage or spill on the track.

SRXL is a single wire serial data protocol developed by Spektrum that allows channel data from SRXL equipped receivers to be transmitted to flight controllers and other a...

SRXL2 is a powerful bi-directional communications protocol that improves the speed, security, and richness of data transfer between your radio system and compatible on-bo...

Horizontal stabilizer.

When the air flowing over the wing cannot produce enough lift to support the weight of the model. This can happen if the modeler flies too slowly, or if the wing is at a...

The maneuver in which the model is flown to a point where the rotor disk/main wing is vertical, reaches an apex/stalls, then is turned about the yaw axis to continue in a...

The model must be brought exactly parallel to the flight path and flown in an absolutely straight and level path. Inverted Flight: The model flies along a straight line i...

This is a trim function on many computer radios, allowing trim adjustments during setup while still allowing the full trim function in flight.
