CA Glue
CA stands for "Cyanoacrylate" (commonly referred to as "super glue" outside the hobby). This glue is fast drying and works well on wood, most plastics and other building materials. It can destroy foam surfaces.

Camber
Camber is the angle of the wheel relative to vertical, as viewed from the front or the rear of the car. If the wheel leans in towards the chassis, it has negative camber; if it leans away from the car, it has positive camber.

In an airplane, camber refers to the arc of an airfoil's mean centerline.

carbon fiber
An extremely strong thin fiber made by pyrolyzing synthetic fibers, such as rayon, until charred. Very light and stronger than steel, is used through out electric planes and on larger nitro ones also(for pushrod set ups etc.)

Carburetor
The carburetor on a glow or gas engine mixes fuel and air into just the right proportions as to cause an efficient "burn" or explosion in the combustion chamber of the engine. To "lean" a mixture means there is insufficient fuel. To "rich" a mixture means there is too much fuel for the motor to efficiently burn.

Caster
Caster is the angle to which the steering pivot axis is tilted forward or rearward from vertical, as viewed from the side. If the pivot axis is tilted backward (that is, the top pivot is positioned farther rearward than the bottom pivot), then the caster is positive; if it's tilted forward, then the caster is negative.

Cavitation
The sudden formation and collapse of low-pressure bubbles in fluids by means of mechanical forces, such as those resulting from rotation of a propeller. This term is more familiar in boating, but can also occur with airplanes.

Center of Buoyancy (CB)
The center of buoyancy in a floating ship/vessel is the point at which all of the body parts exactly balance each other. In a balanced vessel, the metacenter remains directly above the center of buoyancy regardless of the tilt of the floating ship. When a ship tilts, one side displaces more water than the other side, and the center of buoyancy moves and is no longer directly under the center of gravity; regardless of the amount of the tilt, the center of buoyancy remains directly below the metacenter. If the metacenter is above the center of gravity, buoyancy restores stability when the ship tilts. If the metacenter is below the center of gravity, the boat is unstable and capsizes.

Center of Gravity
Generally used as a reference to the balance point on an aircraft. This is the point at which the model balances for the best balance of manuverabilty and stability. A good starting point for most conventional scratch built aircraft is 25 - 30% of the average wing chord.

Center of Lift
Point on the longitudinal axis of an aircraft where the lift created by the airplane's surface area is equal on both sides of the axis. For an airplane to be aerodynamically stable, the center of lift should be aft of the center of gravity.

Chicken Stick
A chicken stick is a stick used to start and airplane by turning it's propeller in a flipping motion. People use it so they don't get their fingers cut off or wacked. It is simply a stick with a small bit of rubber on one end to make contact with the prop.

Choking the Engine
Choking the engine refers to placing an object over the carburetor in order to create suction that will draw fuel from the tank into the combustion cylinder of the engine. This is also known as "priming" the engine. On some older setups, one can squirt fuel directly into the carburetor to accomplish the same result.

Chord
The distance from the leading edge to the trailing edge of the flying surface. On airplanes, this is usually in reference to the the main wing or horizontal stabilizer. For helicopters this is usually used in reference to the main rotor blades.

Clevis
A clip like devise normally at the end of a control rod which connects to a control horn. It transmits linear motion into rotational motion and causes the rudder, elevetor, ailerons to pivot. Clevis's can also be used on throttle linkage, struts or other areas to provide attachment.

Clunk
A fuel pickup at the end of a flexible tube inside a fuel tank. Gravity ensures that the clunk is always at the bottom, enabling fuel to be collected whatever the orientation of the fuel tank.

Clunk
This is the heavy weight at the end of a fuel line within a fuel tank that keeps the line "sunken" into the fuel regardless of the attitude of the tank (example: if an airplane flies inverted, gravity causes the clunk to fall to the "top" of the tank where the fuel is sitting while the plane is inverted).

Collective Pitch
Refers to a pitch change that is applied equally to all of the main rotor blades to change the amount of thrust generated by the main rotor blades. This will be positive pitch or negative pitch.
