1. Sarrera
The FMS Reflex V2 Flight Controller is an advanced gyro stabilizer designed to enhance the flight experience of various RC aircraft. This user-upgradable flight controller can be easily reprogrammed with different model files via dedicated software, allowing pilots to adapt the unit to different aircraft as their skills progress. The Reflex V2 acts as a "co-pilot," providing stability and control assistance for a more confident and enjoyable flight.

2. Ezaugarri eta funtzio nagusiak
The Reflex V2 offers three distinct flight modes, selectable via a 2 or 3-position switch on your transmitter. When using a 2-position switch, the system toggles between Stabilized and Optimized modes.
- Stabilized Mode: Ideal for beginners, this mode rapidly levels the aircraft from any attitude when activated. It utilizes accelerometer and gyro data to automatically return the aircraft to a level flight path when control sticks are released, providing enhanced stability and peace of mind.
- Optimized Mode: Employing advanced solid-state gyros, this mode actively maintains aircraft attitude by counteracting inflight disturbances such as wind gusts or crosswinds. It provides a more locked-in feel while still allowing full pilot control.
- OFF modua: In this mode, all gyro functionality is disabled. The aircraft is flown entirely manually, with no electronic assistance from the Reflex V2 system.

4. Konfigurazioa eta instalazioa
Proper installation is crucial for optimal performance. Always refer to your aircraft's specific manual for mounting recommendations.
4.1 Kontrolagailua muntatzea
- Mount the Reflex V2 securely in your aircraft, ensuring it is level and free from vibrations.
- The orientation of the controller is critical. Ensure the arrow on the unit points towards the front of the aircraft.
- Use double-sided foam tape for vibration dampening and secure attachment.
4.2 Kableatutako konexioak
Connect the Reflex V2 to your receiver and servos according to the following general guidelines. Specific channel assignments may vary based on your aircraft and radio system.
- Connect the AIL (Aileron), ELE (Elevator), THR (Throttle), and RUD (Rudder) ports on the Reflex V2 to the corresponding channels on your receiver.
- Connect your servos to the output channels (CH1, CH2, CH3, CH4) on the Reflex V2. Ensure correct polarity.
- If using SBUS or PPM, connect the SBUS/PPM MODE port to your compatible receiver.
- Power the Reflex V2 via your ESC's BEC or a separate power source, ensuring correct voltage.

4.3 Initial Calibration and Programming
After physical installation, the Reflex V2 requires initial calibration and configuration using the FMS Reflex V2 software. This software allows you to:
- Select the appropriate aircraft profile (e.g., Warbird, Trainer, Jet).
- Calibrate the gyros and accelerometers.
- Adjust gain settings for each flight mode.
- Configure channel assignments and servo directions.
- Eguneratu firmwarea.
Connect the Reflex V2 to your computer via the USB port and launch the software. Follow the on-screen instructions for calibration and setup.
5. Operating the Reflex V2
Once installed and configured, operating the Reflex V2 is straightforward. Use the assigned switch on your transmitter to toggle between the desired flight modes:
- Before Takeoff: Always ensure the Reflex V2 is in the desired mode (e.g., Stabilized for initial flights) and perform a control surface check.
- In-Flight Mode Switching: You can switch modes during flight. Observe the aircraft's behavior and adjust your flying style accordingly.
- Lurreratzea: For precise landings, some pilots prefer to switch to OFF mode, while others may find Stabilized mode helpful for maintaining level wings.
