2. Center of gravity of an aircraft - Wikipedia

   en.wikipedia.org/wiki/Center_of_gravity_of_an...

   Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. The CG limits are indicated in the airplane flight manual. The area between the limits is called the CG range of the aircraft. Weight and Balance

3. Kline–Fogleman airfoil - Wikipedia

   en.wikipedia.org/wiki/Kline–Fogleman_airfoil

   Aircraft wing showing the KFm4 Step. In the early 1960s, Richard Kline wanted to make a paper airplane that could handle strong winds, climb high, level off by itself and then enter a long downwards glide. After many experiments he was able to achieve this goal. He presented the paper airplane to Floyd Fogleman who saw it fly and resist stalling.

4. Aircraft flight dynamics - Wikipedia

   en.wikipedia.org/wiki/Aircraft_flight_dynamics

   A control system includes control surfaces which, when deflected, generate a moment (or couple from ailerons) about the cg which rotates the aircraft in pitch, roll, and yaw. For example, a pitching moment comes from a force applied at a distance forward or aft of the cg, causing the aircraft to pitch up or down.

5. Carl Goldberg Products - Wikipedia

   en.wikipedia.org/wiki/Carl_Goldberg_Products

   Carl Goldberg Models manufactures radio-controlled (RC) aircraft and components. This company was purchased by Great Planes Model Manufacturing on August 24, 2007. The model shown on the right was in production during negotiations and is considered to be either the last model produced under the previous owner or the first under the new one; it ...

6. Chord (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Chord_(aeronautics)

   Mean aerodynamic chord (MAC) is defined as: [6] = (), where y is the coordinate along the wing span and c is the chord at the coordinate y.Other terms are as for SMC. The MAC is a two-dimensional representation of the whole wing. The pressure distribution over the entire wing can be reduced to a single lift force

7. Radio-controlled aircraft - Wikipedia

   en.wikipedia.org/wiki/Radio-controlled_aircraft

   A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...

8. Aerodynamic center - Wikipedia

   en.wikipedia.org/wiki/Aerodynamic_center

   Within the assumptions embodied in thin airfoil theory, the aerodynamic center is located at the quarter-chord (25% chord position) on a symmetric airfoil while it is close but not exactly equal to the quarter-chord point on a cambered airfoil.

9. Aspect ratio (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Aspect_ratio_(aeronautics)

   An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56). In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord.It is equal to the square of the wingspan divided by the wing area.
