Hi
These r/c terms might be useful. While reading about specific models you may come across some words that you don’t understand, so see if you can get those here.
3D
Term describing a type of flight pattern, which is characterized by the performance of very specialized aerobatic. maneuvers below the model's normal stall speed. Examples include torque rolls, 'walk in the park', harriers, hangers, etc.
For helicopters: combining two or more maneuvers into one maneuver. Examples: rolling circle, inverted backwards loop.
3F
Slang abbreviation for flip flop flying. Similar to 3D, but without the finesse.
The shape of the wing when looking at its profile. Usually a raindrop type shape.
For helis: The rotor disk is the effective wing, and airfoil refers to the shape of the blades.
Angle of attack
The angle that the wing penetrates the air. As the angle of attack increases so does lift, up to a point.
Articulated Rotor
Itis a rotor head which allows the blades to flap, drag and feather.
Aspect ratio
The ratio of the wingspan to the wing's chord (depth). For sailplanes this number will be larger than sport planes, which will generally be larger than a "jet" style aircraft.
Autorotation
The ability of a rotary wing aircraft to land safely without engine power. This maneuver uses the stored energy in the rotor blades to produce lift at the end of decent, allowing the model to land safely.
Axis
The line around which a body rotates.
