A flight mode programmed into the transmitter that employs different pre-programmed curve sets to govern the behavior of a model. Normal mode is characterized by a linear throttle curve (full down stick = idle, full up stick = wide open throttle) mixed to a non-linear pitch curve (generally 0 degrees pitch at half stick). Normal mode is used for spooling up a model for takeoff and for spooling down after landing. Some pilots do not even leave the ground in normal mode, preferring to fly in Idle up mode constantly.
