Reflex system overview

  1. Utilizes a high-speed 32-bit ARM processor onboard.
  2. Sensors: Solid-state 3 axis gyro and 3 axis accelerometer.
  3. Automatically recognizes SBUS/PPM/PWM systems, compatible with all radio systems with 4 channels or above.
  4. Reflex V3 version can be connected to a mobile app via Bluetooth after power-on, unlocking parameter setting functions (available for non-FMS models as well).
  5. User-friendly operation: Synchronize required parameters through computer software or mobile app, connect Reflex V3 to the receiver, and set up the corresponding channels and directions on the remote controller. (Note: Parameter setting functions are only supported by the mobile app.)

Reflex functions
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 rapidly 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.

Note: The aircraft will maintain level flight with 50~60% throttle. The aircraft will climb under full throttle.

OFF-
Turns off all gyro functionality, the aircraft is flown completely manually when the gyro is off.

Optimized mode-
Utilizing advanced solid-state gyros, the Reflex system maintains aircraft attitude by counteracting inflight upsets- from gusts to crosswinds. With Reflex, even small aircraft will fly with the confidence of something much larger!

Operation instructions

  1. SBUS\PPM input: Connect the 3-wire cable into the port that is labelled SBUS\PPM. Ensure that the polarity of the cable is correct. The default channel assignment is aileron, elevator, throttle, rudder and mode switch (Note: Different aircraft may have different flight modes, refer to your aircraft manual for more information). If the channel assignment does not fit that of your transmitter system, change the channel order from your transmitter.FMS-Reflex-V3-Stable-Flight-Controller-image (2)
  2. PWM: Connect the throttle and flight surface channels to their corresponding ports on the Reflex system. Connect a 3 wire cable from the channel that is controlled by your 3 position switch to the port labelled SBUS\PPM to control the gyro mode.FMS-Reflex-V3-Stable-Flight-Controller-image (3)

If you are using a 4 channel transmitter, use the included jumper to select between flight modes by plugging it into the “gyro mode input” port.

Note: The flight controller operates under stabilized mode by default. Plugging the jumper cable into the gyro mode input port changes the gyro mode to Optimized mode.

Operation: Turn on your transmitter first, then turn on your receiver. Set your aircraft down on a flat surface and have it remain level (the flight controller LED will flash rapidly). When the gyro is properly calibrated, the aileron servos will cycle 3 times in rapid succession; then the elevator will cycle 3 times in rapid succession- this signifies that the aircraft is ready for flight. Check that your 3-position switch is functional and that all channels are operating correctly.

NOTE
GYRO LED ON- Stabilized mode
GYRO LED FLASHES SLOWLY- Gyro off
GYRO LED FLASHES RAPIDLY- Optimized mode

  1. What is the optimizing mode and manual mode active bar adjustment?

    Steve Milam asks What is the optimizing mode and manual mode active bar adjustment?
    Manuals+ clarified question
    Question

    What is Optimized mode and how do I adjust the active bar settings?

    Answer

    Based on the FMS Reflex V3 manual, here is the breakdown of the modes and adjustment settings:

    • Optimized Mode: This mode utilizes advanced solid-state gyros to maintain the aircraft's attitude by counteracting inflight upsets such as wind gusts or crosswinds. Unlike Stabilized mode, which automatically levels the plane, Optimized mode helps the aircraft fly more smoothly and resist external turbulence while still allowing for manual control.
    • Manual Mode (OFF): In this mode, all gyro functionality is turned off, and the aircraft is flown completely manually by the pilot.
    • Adjustment (Parameter Setting): While the manual does not use the specific term "active bar," it describes the adjustment process via the FMSHOBBY mobile app (connected via Bluetooth). To adjust parameters:
      1. Connect the Reflex V3 to the mobile app.
      2. Navigate to the Reflex Model Information page and click Parameter setting.
      3. For FMS models, you can adjust Aileron, Elevator, and Rudder settings. For non-FMS models, you can also adjust the Gyroscope Setting.
      4. After moving the adjustment sliders (bars) to your desired levels, you must click the Synchronize button at the bottom of the page to save the settings to the controller.

    Note: On the Reflex V3, the LED will flash rapidly when Optimized mode is active, and flash slowly when the gyro is OFF (Manual mode).

    Question

    How do I reverse the gyro correction direction for the ailerons on the FMS Reflex V3?

    Answer

    To reverse the gyro correction direction on the FMS Reflex V3, you must use the FMSHOBBY mobile app (available on the App Store or Google Play) via Bluetooth, as the V3 version supports parameter settings through this interface.

    Follow these steps to adjust the directions:

    1. Connect to the App: Power on your Reflex V3, launch the FMSHOBBY app, and connect to your device (default password is 123456).
    2. Enter Parameter Settings: On the "Reflex Model Information" page, click the Parameter setting button at the bottom of the screen.
    3. Adjust Directions: Under the settings for your specific model (or "Other models" if using a custom setup), you will find options for Aileron setting. Within this menu, you can toggle the direction of the gyro correction.
    4. Synchronize: After making the change, click the Synchronize button at the bottom of the page to save the new parameters to the flight controller.

    Note: The manual specifies that while basic parameters can be viewed on a computer, detailed parameter setting functions like reversing directions are specifically supported by the mobile app.

  3. The Reflex V3 in my piper cub model has become unstuck from the model. What is the correct location and orientation of the V3 relative to the model?

    Manuals+ clarified question
    Question

    What is the correct location and orientation for the FMS Reflex V3 flight controller in a Piper Cub model?

    Answer

    To ensure the FMS Reflex V3 flight controller functions correctly in your Piper Cub, follow these installation guidelines:

    • Location: The controller must be mounted on a flat, level surface within the aircraft. It is typically placed near the center of gravity (CG) for optimal performance.
    • Orientation: The unit must be mounted level relative to the aircraft's flight path. While the manual does not specify a single fixed direction (as parameters can be adjusted via the app), it is standard practice to mount it with the labels facing up and the ports facing either the front or rear of the plane, ensuring it is perfectly parallel to the fuselage floor.
    • Calibration: After re-securing the device, you must calibrate it. Place the aircraft on a flat surface and power it on. The LED will flash rapidly during calibration. Once finished, the aileron servos will cycle 3 times, followed by the elevator servos cycling 3 times, indicating the system is ready.

    Note: Since the Reflex V3 supports customizable parameters via the FMSHOBBY app, ensure you have the correct "Piper Cub" (e.g., 1400mm J3 Cub V4 or 1700mm PA-18 Super Cub) profile loaded to match the controller's physical orientation to the software's expectations.
