4. Setup and Installation
4.1 Physical Installation
Mount the FC151 unit securely in your RC aircraft or quadcopter. Ensure it is oriented correctly according to the "HEAD DIRECTION" arrow on the unit. The compact size allows for flexible placement, but avoid areas with excessive vibration or electromagnetic interference.

4.2 Wiring Connections
Connect the FC151 to your receiver and servos using appropriate cables. The unit features clearly labeled ports for system power (SYS), aileron (AIL1, AIL2), elevator (ELE), rudder (RUD), and mode selection (MODE). If using S.BUS, refer to your receiver's manual for proper connection to the FC151's S.BUS port.

4.3 Control Surface Types and Mixing
The FC151 supports various aircraft configurations. Ensure your transmitter is set up correctly for the chosen aircraft type, and then configure the FC151 accordingly. The unit supports:
- Single Aileron Aircraft
- Double Aileron Aircraft
- Fly Wing Aircraft (Delta Wing)
- V-Tail Aircraft
Flaperon mixing is also supported. Refer to the diagram below for visual guidance on control surface configurations.

4.4 Sensitivity Adjustment
The FC151 allows independent sensitivity adjustment for aileron (AIL), elevator (ELE), and rudder (RUD) axes. Use a small screwdriver to carefully adjust the potentiometers labeled AIL, ELE, and RUD on the top of the unit. Start with lower sensitivity settings and gradually increase as needed during test flights to achieve desired stability without overcorrection.
4.5 Flight Mode Selection
The FC151 supports different flight modes, including auto-level and modes suitable for aerobatic/3D flying. These modes can be switched via an extra channel on your transmitter, connected to the FC151's MODE input. Consult the LED indicators for current mode status.
5. Operation
Once installed and configured, the FC151 will provide stabilization during flight. The system continuously monitors the aircraft's attitude and makes rapid corrections to maintain stability. For advanced users, programming via the onboard button and LEDs allows for fine-tuning of parameters. Refer to the specific programming sequence detailed in the full product manual (if available) or Dualsky's official website for detailed steps.
Ensure your transmitter is properly calibrated and all control surfaces respond correctly before attempting flight.
6. Maintenance
- Cleaning: Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Inspection: Periodically inspect all wiring connections for looseness or damage.
- Environmental Conditions: Avoid exposing the unit to extreme temperatures, moisture, or direct sunlight for prolonged periods.
- Firmware: Check the Dualsky official website for any available firmware updates.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to FC151 | Incorrect wiring, faulty power source, damaged cable. | Check all power connections. Ensure battery is charged. Inspect cables for damage. |
| Unstable flight / Overcorrection | Sensitivity too high, incorrect mounting, vibration. | Reduce sensitivity settings. Re-mount the unit securely. Check for excessive vibrations. |
| Incorrect control response | Incorrect servo direction, wrong aircraft type selected, faulty servo. | Verify servo directions in transmitter. Confirm correct aircraft type setting on FC151. Test servos independently. |
| Mode switching not working | Extra channel not configured, incorrect wiring to MODE input. | Ensure transmitter channel is assigned and connected correctly to the FC151 MODE input. |
