4. Setup
4.1 Bhatiri Connection
The Crux3 drone uses an XT30 connector for its power input. It is recommended to use 2s 350mAh / 400mAh / 450mAh / 520mAh LiPo batteries for optimal flight performance. Ensure the battery is fully charged before connecting.
- Carefully align the XT30 connector from the battery with the XT30 connector on the drone.
- Push firmly until the connectors are fully seated.
- Secure the battery to the drone's frame using the provided battery strap to prevent movement during flight.

4.2 Kuiswa kwePropeller
The Crux3 uses Gemfan 3018-2 propellers. Ensure propellers are installed correctly according to motor rotation direction.
- Identify the correct propeller for each motor (clockwise and counter-clockwise).
- Gently push the propeller onto the motor shaft until it sits flush.
- Ensure the propeller is securely attached but do not overtighten if using screws.

4.3 Kubatanidza neTransmitter
The binding process varies depending on the receiver version of your Crux3 drone. Refer to your transmitter's manual for specific binding instructions.
- Internal SPI Frsky Version: Compatible with ACCST D8 / D16 modes. D8 mode is recommended.
- Internal SPI Flysky Version: Compatible with AFHDS and AFHDS-2A Flysky transmitters.
- Internal SPI DSM2/X Version: Compatible with Spektrum radio or DSM2/X multiprotocol.
- External Frsky RXSR Version: ACCST D16 sbus output.
- External TBS Crossfire Nano Version: Requires TBS Crossfire transmitter.
Typically, you will need to put both the drone's receiver and your transmitter into binding mode. Consult the flight controller firmware documentation (e.g., Betaflight) for detailed receiver setup and binding procedures.
5. Operating Instructions
5.1 Gadziriro Yendege
- Ensure all components are securely attached and propellers are free from damage.
- Verify battery is fully charged and properly connected.
- Power on your FPV goggles and ensure a clear video feed from the drone's CADDX ANT camera.
- Power on your radio transmitter and ensure it is bound to the drone.
- Place the drone on a flat, stable surface in an open area, clear of obstacles.
5.2 Yekutanga Kudzora Ndege
Familiarize yourself with the basic controls on your transmitter:
- Mota: Controls altitude (usually left stick, vertical).
- Yaw: Rotates the drone left or right (usually left stick, horizontal).
- Pitch: Tilts the drone forward or backward (usually right stick, vertical).
- Mupumburu: Tilts the drone left or right (usually right stick, horizontal).
Arm the motors using the designated arming switch on your transmitter (refer to your Betaflight configuration). Once armed, slowly increase throttle for takeoff.
5.3 Insta360 Go Camera Compatibility
The Crux3 drone is designed to be compatible with the Insta360 Go Camera. This allows for capturing high-quality stabilized footage during your flights. Ensure the Insta360 Go is securely mounted to the drone's designated mount point before flight.

6.1 Mazano Ekugadzirisa Zvese
- Propeller Inspection: Regularly check propellers for cracks, bends, or nicks. Replace damaged propellers immediately as they can cause vibrations and affect flight performance.
- Frame Inspection: After any hard landing or crash, inspect the carbon fiber frame for cracks or damage.
- Kuchenesa Motokari: Keep motors free from dirt, dust, and debris. Use compressed air to clean if necessary.
- Kuongorora kwechikamu: Ensure all screws are tight and electrical connections (e.g., XT30, motor wires) are secure.
- Battery Care: Store LiPo batteries at storage voltage (around 3.8V per cell) when not in use. Do not overcharge or over-discharge.
7. Kugadzirisa matambudziko
7.1 Matambudziko Anowanikwa uye Magadzirirwo
- Drone not arming: Check if the arming switch on your transmitter is correctly configured in Betaflight. Ensure the drone is level and no pre-arm conditions (e.g., low battery, no receiver signal) are preventing arming.
- No video feed: Verify the CADDX ANT camera is properly connected to the flight controller. Check your FPV goggles for correct channel selection and battery level.
- Unstable flight/Vibrations: Inspect propellers for damage and ensure they are securely attached. Check for loose motors or frame components. Recalibrate accelerometer in Betaflight if necessary.
- Loss of control/Range issues: Ensure your receiver is properly bound to your transmitter. Check for antenna damage on both the drone and transmitter. Avoid flying in areas with high interference.
- Motors not spinning: Check motor connections to the ESC. Ensure motors are not obstructed. Verify motor output in Betaflight configurator.
For more advanced troubleshooting or configuration, refer to the official Betaflight documentation and community forums for the CrazybeeX flight controller.
