3 flight modes are available: Stabilized, Optimized or off. This is controlled with a 2 or 3 position switch on the transmitter. When assigned to a 2 position switch, the Reflex system switches between stabilized and optimized modes. Stabilized Mode- Designed for beginners, Reflex will level the aircraft from any attitude when this mode is activated. Stabilized mode combines accelerometer and gyro data to determine how to level the aircraft when the control sticks are released- giving pilots absolute peace of mind. OFF- Turns off all gyro functionality, the aircraft is flown completely manually when the gyro is off. Optimized Mode- Utilizing advanced solid-state , the Reflex system maintains aircraft attitude by counteracting inflight upsets- from gusts to crosswinds.
