drag, which can really hurt a glider's performance. There are two ways to reduce the yaw of the
fuselage, differential (ADIF) and rudder coupling (A->R). Both should be used together, but you
only find ADIF in the glider menus.
Aileron differential causes the ailerons to automatically move with more UP than DOWN
motion, which helps to reduce induced drag. It helps, along with rudder-coupling, to make the
fuselage point straight into the oncoming air stream (this is also called "coordinating the turn").
The amount of differential is highly dependent on the model configuration. A good
starting point is for the down aileron to move 50% to 75% as much as the up-moving aileron.
