FMS Reflex V2 Flight Controller Gyro Stabilizer User Manual

1. Introduction

The FMS Reflex V2 Flight Controller is an advanced gyro stabilization system designed to enhance the flight experience of various RC aircraft, including fixed-wing airplanes, warbirds, and helicopters. It acts as a 'co-pilot' to assist pilots in maintaining stable and controlled flight, offering different modes to suit varying skill levels and flight conditions. This manual provides essential information for the proper setup, operation, and maintenance of your Reflex V2 unit.

2. Key Features

• Reprogrammable: The Reflex V2 can be easily reprogrammed with different model files using dedicated software, allowing for versatility across various aircraft types and pilot preferences.
• Three Flight Modes: Offers Stabilized, Optimized, and Off modes, selectable via a 2 or 3-position switch on your transmitter.
• Compact Design: Small form factor for easy integration into most RC aircraft.

3. Setup and Connections

Proper connection of the Reflex V2 to your receiver and aircraft's control surfaces is crucial for correct operation. Refer to the diagrams below for port identification and typical wiring.

3.1 Port Identification

• AIL (Aileron): Connects to the aileron channel of your receiver.
• ELE (Elevator): Connects to the elevator channel of your receiver.
• THR (Throttle): Connects to the throttle channel of your receiver.
• RUD (Rudder): Connects to the rudder channel of your receiver.
• CH1-CH4: Auxiliary channels for additional functions or control surfaces.
• USB: Used for connecting the flight controller to a computer for software configuration and firmware updates.
• UART: Universal Asynchronous Receiver/Transmitter port, typically for advanced telemetry or peripheral connections.
• SBUS PPM MODE: Input for SBUS or PPM compatible receivers, allowing for single-line connection.
• LED: Status indicator light.

3.2 Software Reprogramming

The Reflex V2 requires specific software for initial setup, calibration, and reprogramming with different aircraft profiles. This software is typically available from the manufacturer's website. Connect the unit to your computer via the USB port and follow the software instructions for configuration.

4. Operating Modes

The FMS Reflex V2 offers three distinct flight modes to cater to different piloting needs. These modes are typically selected using a 2 or 3-position switch on your radio transmitter.

4.1 Stabilized Mode

Designed primarily for beginners, this mode provides significant assistance in maintaining stable flight. When the control sticks are released, the Reflex V2 will rapidly level the aircraft from almost any attitude. It utilizes accelerometer and gyro data to achieve this, offering pilots a sense of security and making initial flight training easier.

4.2 Optimized Mode

In Optimized Mode, the Reflex V2 uses advanced solid-state gyros to actively maintain the aircraft's attitude. It counteracts external disturbances such as wind gusts and crosswinds, providing a smoother and more precise flight experience without fully taking over control. This mode is suitable for intermediate to advanced pilots who desire enhanced stability and precision.

4.3 Off Mode

When Off Mode is selected, all gyro functionality of the Reflex V2 is disabled. The aircraft is flown completely manually, relying solely on the pilot's direct control inputs. This mode is for experienced pilots who prefer full manual control or for specific maneuvers where gyro assistance is not desired.
