3. Setup and Assembly
This section provides general guidance for assembling your HGLRC 75Whoop V2 frame kit. Specific component installation instructions may vary based on your chosen flight controller, motors, and camera.
3.1 Frame and Hood Assembly
- Carefully unpack all components from the kit.
- Identify the main frame and the separate hood piece.
- Align the hood with the designated mounting points on the main frame.
- Secure the hood using the provided small screws. Ensure they are tightened sufficiently to hold the hood firmly without over-tightening, which could damage the plastic.

3.2 Component Installation (General Guidelines)
- Flight Controller: Mount your flight controller (e.g., SPECTER 10A AIO) onto the central mounting holes (25.5x25.5mm) using appropriate standoffs and screws. Use the provided rubber dampers if necessary to reduce vibrations.
- Motors: Attach your motors (e.g., SPECTER 0802-21000KV) to the motor mounting points (Φ6x3) on each arm. Ensure motor wires are routed safely and securely.
- Camera: Install your FPV camera (e.g., Runcam Nano4) into the designated camera slot within the hood. Ensure it is securely fastened and has a clear field of view.
- Propellers: Once all electronics are installed and tested, attach the propellers (e.g., Gemfan1610 inches) to the motors. Pay attention to the correct rotation direction for each propeller.
Refer to the specific manuals for your chosen flight controller, motors, and camera for detailed wiring and configuration instructions.
4. Operating Considerations
As this product is a drone frame, operational instructions primarily pertain to the complete FPV drone once assembled. Always ensure all components are correctly installed and configured before flight.
4.1 Pre-Flight Checks
- Verify all screws are tight and components are securely mounted.
- Inspect the frame for any cracks or damage before each flight.
- Ensure propellers are correctly installed and free from damage.
- Confirm battery is fully charged and properly connected.
- Perform a radio control range check and verify all control surfaces respond correctly.
4.2 Flight Environment
- This frame is designed for indoor use due to its ultra-lightweight nature and whoop style.
- Fly in open, clear areas free from obstacles and people.
- Avoid flying near water, heat sources, or strong electromagnetic interference.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your HGLRC 75Whoop V2 frame.
- Inspection: After each significant crash or hard landing, inspect the frame for any signs of stress, cracks, or deformation. Pay close attention to motor mounts and propeller ducts.
- Cleaning: Use a soft, dry cloth or a small brush to remove dust and debris from the frame. Avoid using harsh chemicals that could damage the plastic material.
- Fasteners: Periodically check all screws and fasteners to ensure they remain tight. Vibrations during flight can sometimes loosen them.
- Component Check: Ensure all mounted components (flight controller, motors, camera) are still securely attached to the frame.
- Storage: Store the frame in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
6. Troubleshooting
This section addresses common issues related to the frame itself. For issues related to flight performance or electronics, refer to the manuals of your specific components.
6.1 Frame-Related Issues
- Issue: Frame appears bent or cracked after a crash.
Solution: While the frame is designed to be durable, severe impacts can cause damage. Inspect the extent of the damage. If structural integrity is compromised, replace the frame to ensure safe flight. - Issue: Components (e.g., flight controller, camera) are loose on the frame.
Solution: Re-tighten mounting screws. If screws are stripped or mounting holes are damaged, consider using slightly larger screws (if appropriate) or applying a small amount of thread locker (non-permanent) to prevent loosening. Ensure rubber dampers are correctly seated if used. - Issue: Excessive vibration originating from the frame.
Solution: Check for any loose components or screws. Ensure motors are securely mounted and not causing any part of the frame to flex abnormally. Verify propellers are balanced and undamaged.
