1. Introduction and Overview
The Spektrum Flight Controller: Carbon Cub S+ (Model SPMA3232) is an advanced electronic speed controller designed for the Carbon Cub S+ aircraft. It integrates SAFE+ technology to provide a stable and enjoyable flying experience for pilots of all skill levels. This manual provides essential information for setting up, operating, and maintaining your flight controller.

2. Setup
Proper setup is crucial for safe and optimal performance of your flight controller. Ensure all connections are secure and the unit is correctly installed in your aircraft.
2.1 Component Identification
The flight controller integrates with your aircraft's receiver and servos. Familiarize yourself with the various ports for throttle, ailerons, elevator, and rudder.
2.2 Installation
Install the flight controller securely within the aircraft fuselage, ensuring it is level and free from vibrations. Connect the appropriate servo leads and power supply as per your aircraft's specific instructions.
3. Operating Instructions
The Spektrum Flight Controller with SAFE+ technology offers various modes to assist with flight control and enhance your flying experience.
3.1 Flight Modes (SAFE+ Technology)
SAFE+ technology provides progressive flight modes, allowing you to gradually increase control as your skills improve. These modes are typically selected via a switch on your compatible Spektrum transmitter.
- Beginner Mode: Offers limited pitch and bank angles with self-leveling capabilities, making takeoffs and landings easier. This mode actively works to prevent costly mistakes.
- Intermediate Mode: Provides more freedom in pitch and bank compared to Beginner Mode, with no self-leveling. This mode allows for more dynamic flight while still offering some stability.
- Experienced Mode: Removes all pitch and bank limits, and self-leveling is disabled, giving you full control for advanced maneuvers and aerobatics.
3.2 Advanced SAFE+ Features
- Panic Recovery Mode: At the push of a button, the aircraft will automatically return to stable, level flight, helping to prevent crashes.
- Autoland: Push and hold a designated button, and the airplane will automatically land near the takeoff location.
- Holding Pattern: Pause your flight with the push of a button. The aircraft will enter a holding pattern. Push the button again to cancel the command and regain control.
- Virtual Fence: This feature keeps the airplane from flying too far away by automatically turning it back when it reaches a predefined boundary. The airplane will rock its wings to indicate you have control again.
3.3 Takeoff and Landing
For ground takeoffs, ensure a flat surface. For hand launches, gently toss the aircraft forward with sufficient throttle. When landing, maintain a small amount of throttle (around 10%) and gently pull up on the elevator for a smooth touchdown. Avoid cutting the throttle completely, as this can lead to a sudden descent.
3.4 Real-Time Telemetry
The DXS transmitter provides real-time telemetry feedback. A multi-colored LED on the transmitter indicates the approximate flight battery power remaining:
- Green: More than ~50% battery remaining.
- Yellow: ~20-50% battery remaining.
- Red: Less than 20% battery remaining.
4. Maintenance
Regular maintenance ensures the longevity and reliable performance of your Spektrum Flight Controller.
- Inspect all wiring and connectors for signs of wear or damage before each flight.
- Ensure the flight controller is securely mounted and free from excessive vibrations.
- Keep the unit clean and free from dust, dirt, and moisture.
- Check control surfaces for proper movement and trim settings.
5. Troubleshooting
If you encounter issues with your flight controller, refer to the following common troubleshooting steps:
- No Control Response: Ensure the transmitter is bound to the receiver and the flight battery is fully charged and properly connected.
- Unstable Flight: Verify that the flight controller is securely mounted and correctly oriented. Check for any loose servo connections or damaged control surfaces.
- Incorrect Flight Mode Behavior: Confirm that the flight mode switch on your transmitter is functioning correctly and that the aircraft is calibrated according to the manual.
