Setup
Installation and Wiring
Mount the FC151 securely in your RC airplane using the provided double-sided tape. Ensure the unit is oriented correctly according to your desired setup. Connect the FC151 to your receiver and servos as per your aircraft's wiring diagram. The FC151 supports HV inputs.
Configuration Settings
The FC151 can be programmed via a button and LED indicators. Refer to the chart below for specific settings related to installation direction and airplane type.
| Item | L2 (LED) | |||
|---|---|---|---|---|
| L1 (LED) | Blue (default) | Green | Red | Yellow |
| Face up | Face down | Face right | Face left | |
| Blue (Install direction) | Normal | Delta wing | V-tail | |
| Green (Airplane type) | ||||
Operating
LED Status Indicators
The FC151 uses two LEDs (LED1 and LED2) to indicate its current status and operating mode. Understanding these indicators is crucial for proper operation.
| LED1 STATUS | FC151 STATUS | ||
|---|---|---|---|
| Green flashing | Initializing | ||
| Green solid | Initialization completed, signal OK | ||
| Red solid | Initialization completed, no signal| LED2 STATUS | FC151 STATUS | |
| Blue on for 0.5 second | In gyro off mode | ||
| Green on for 0.5 second | In aerobatic mode | ||
| Red on for 0.5 second | In auto level mode |
Mode Switching
The FC151 supports mode switching via an extra channel on your remote control. This allows you to switch between different flight modes, such as gyro off, aerobatic, and auto-level, during flight.
Maintenance
The DUALSKY FC151 is designed for durability and requires minimal maintenance. Follow these general guidelines:
- Keep Clean: Ensure the unit is free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Inspect Connections: Regularly check all wiring connections for secure fit and signs of wear or damage.
- Avoid Physical Shock: Protect the unit from impacts and vibrations, which can affect its performance.
- Storage: Store the FC151 in a dry, cool environment when not in use.
Troubleshooting
LED Indicators for Diagnostics
- LED1 Red Solid: If LED1 is solid red after initialization, it indicates no signal from the receiver. Check your receiver connections and ensure your transmitter is powered on and bound correctly.
- No Stabilization: If the gyro stabilization does not seem to be working, check LED2 status to ensure you are not in 'gyro off' mode (Blue on for 0.5s). Verify that the sensitivity settings for all 3 axes are correctly adjusted.
- Incorrect Flight Behavior: Double-check the FC151's installation direction and the selected airplane type settings (Normal, Delta wing, V-tail) as per the configuration chart.

User Tips
- Compatibility Check: While designed for RC airplanes, always verify compatibility with your specific aircraft's power system (e.g., electric vs. petrol) and control setup before installation.
- Initial Setup: Take your time during the initial setup and calibration. Incorrect installation direction or airplane type settings can lead to unpredictable flight behavior.
- Sensitivity Adjustment: Experiment with the independent sensitivity adjustments for each axis to fine-tune the stabilization performance to your flying style and aircraft characteristics.
