Aluminum-Brass-Nickel. The components used in the production of non-ringed engines. These engines use an aluminum piston, and a nickel plated brass sleeve. The engine is harder to...

Occurs above the usual power-off stall speed when too much elevator control is input too quickly. This type of stall is usually far more violent than a wings-level, power-off stall...

ATV allows you to preset the maximum travel of a servo to either side from its neutral position. Such settings help tailor control action to suit your flying or driving style.

The tendency of an airplane to yaw in the opposite direction of the roll. For instance, when right aileron is applied, the airplane yaws to the left, thus opposing the turn. Advers...

The act of an aircraft hauling a glider aloft and releasing it.

(propeller) Is speculated to be a dominant mechanism causing rapid fatigue failure near a tip when insufficient or destabilizing tip stiffness exists. The interaction between varia...

Towards the rear. Used such as: "...with an aft center of gravity....".

Adverse yaw, especially on flat-bottom wings, is caused by the difference in airflow density between the bottom and top of the wing. The airflow along the wing’s bottom is denser t...

Hinged control surface located at the trailing edge of each wing, that provides control of the airplane about the roll axis. Ailerons move in opposite directions in order to provid...

Twin elevator servos plugged into separate channels used to control elevator with the option to also have the 2 elevator servos act as ailerons in conjunction with the primary aile...

The shape of the wing when looking at its profile. Usually a raindrop type shape.

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

The Academy Of Model Aeronautics. The official national body for model aviation in the United States. AMA sanctions more than a thousand model competitions throughout the country e...

The angle that the wing penetrates the air. As the angle of attack increases so does lift and drag, up to a point.

Is the opposite of dihedral, having the wing tip centerline lower than the wing root centerline. Anhedral is generally used to aid in the instability of an aircraft to make it more...

The TechOne ARF BUNDLE airplane requires intermediate level building skills. Some included components such as servos and motors do not come pre-installed and will need to be instal...

Freewing offers some of its 90mm jets in "ARF Plus" format. Expanding on the normal ARF format above, The ARF Plus format has ALL components installed already, EXCEPT for the motor...

A proprietary combination of gyros, sensors, and software that helps to stabilize and control the heading of RC aircraft models.

The wingspan divided by the chord. Aspect ratio is important where a wing's efficiency is concerned. A short aspect ratio (short wings) is better for maneuvering, since it all...

Adjustable Travel Volume. Used on many radio transmitters to limit, or extend, maximum throw of a servo. ATV can indicate having a single adjustment which affects both ends of the...

All Up Weight - The total weight of the project. This includes everything needed to make it run or fly. Receiver, servos, batteries, etc. The all up weight of the project.

Any radio channel function other than the four basics (aileron, rudder, elevator and throttle).

A proprietary combination of gyros, sensors, and software that helps to stabilize and control the heading of surface RC models.

This type of roll is one where the aircraft’s fuselage remains exactly on the line of flight while the wings roll about it. Except for a very few jet fighters at high speed (the F-...
