A modern hobby adhesive that cures very quickly.

A strut attaching a wing to the fuselage when the wing is above the fuselage such as biplanes and parasol aircraft.

If you draw a line through the center of the airfoil that's exactly half-way between the top and bottom surface, you get the mean airfoil line. Depending upon the airfoil, it...

An aircraft having the horizontal stabilizer forward of the main wing rather than in the conventional position behind it. Canard aircraft are theoretically more efficient because b...

The part of the engine which controls the speed or throttle setting and lean/rich mixture via setting of the needle valve.

The balance point of a model airplane. For modeling purposes, this is usually considered the point at which the airplane balances fore to aft. This point is critical in regards to...

The location on the top of the wing where the sum of all lifting forces is located.

(propeller) are very predictable, given rotational speed and mass density distribution of a blade. Their contribution to total stress is relatively small.

Center of Gravity. Describes a central point in a given body, where all weight is considered to be concentrated. A central balance point.

A very steep climbing turn where the airplane makes a 180° change of direction.

The number of functions your radio can control. Example: A 7-channel radio has 7 available servo slots used for separate control surfaces or switches. These channels can also be mi...

A hand-held stick used to "flip start" a model airplane engine.

The "depth" of the wing, its distance from leading edge to trailing edge. One of the components used to determine wing area. May vary from root to tip.

The Clevis is a small fastener at the end of a pushrod, usually made from nylon or metal, which connects the pushrod to the control horn. Clevises may frequently be referred to as...

A slotted jaw that allows a limited range of bits to be placed in a tool such as a router, moto-tool, or pin vice.

This effect is the bending of the rotor or propeller blades when stressed.

Any linkage transmitting servo movement to a control surface.

A movable surface such as elevator, rudder, and aileron.

A Conventional Tail is one with the stabilizer mounted directly on the fuselage and is the usual configuration of an aircraft. These are the simplest to construct and seem to be mo...

The covering of an aircraft is the skin which is applied to the airframe, closing it in. On R/C aircraft, it is commonly a fabric or plastic film which is heat applied with an iron...

The large molded fairing around an engine. It serves two purposes: It helps the airflow go smoothly around the front of the airplane and also provides a proper path for cooling air...

When an aircraft flies at a sideways angle relative to the direction being traveled. Can be caused by a crosswind or may be flown intentionally to reduce altitude without increasin...

See "Butterfly".

A stabilizer that is mounted partway up the fin. This is a compromise between the conventional tail and the T-tail, combining some of the major advantages of both.
