Entering a new hobby often presents many new terms that you may not be familiar with, and the RC soaring world is no exception. These definitions are in context to RC sailplanes. We hope this glossary helps make your entry into our fun and exciting hobby smoother:

AUW All up weight. The ready-to-fly weight of the model, including assembly, servos, battery, receiver, ballast, ESC, motor, spinner, propellor and/or any other required equipment.
Camber The amount of deflection in the trailer edge of the wing set up for each flight mode, usually noted in relation to its moulded-flush position. More camber will yield more lift, and less camber will give you more penetration. Usually measured in mm.
CG Center of gravity. This is the balance point of your model, measured at the root of the wing and measured from the leading edge of the wing.
DLG Discus launch glider. Non-motorized radio control gliders that are hand-launched into the air by spinning around and throwing like a discus.
Flight mode Pre-determined settings on the transmitter for different phases of flight. Typical flight modes for a discus launch glider is launch, zoom, speed, cruise, thermal.
Layup Used to describe glider options in weight and sturdiness. Most common layups are Light, Standard and Strong. The Light layup will use a lighter weight carbon fabric to lower the AUW, at the expense of wing stiffness and dent-resistance. Strong layup uses a heavier carbon fabric to increase the AUW, stiffness and dent-resistance. 
Penetration Used to describe how well a model can 'penetrate' the wind. Planes with better penetration will fly against a headwind better, useful when you are downwind and trying to come back to the field.
