4. Setup and Usage
This leveling tool is designed for precise swashplate adjustment on the OMPHOBBY M4 RC Helicopter. Follow these steps for accurate leveling:
- Prepare the Helicopter: Ensure your OMPHOBBY M4 helicopter is powered off and the main rotor blades are removed for safety.
- Insert the Pin: Insert the small metal leveling pin into the central hole of the main leveling tool body. It should fit snugly.
- Position the Tool: Carefully place the leveling tool onto the main shaft of the helicopter, ensuring the three prongs rest evenly on the swashplate. The central pin should align with the center of the main shaft.
- Check Level: Observe the position of the swashplate relative to the leveling tool. The goal is for the swashplate to be perfectly parallel with the tool's prongs, indicating a level position.
- Adjust Swashplate: If the swashplate is not level, adjust the lengths of the servo linkages connected to the swashplate. Make small, incremental adjustments to each linkage until the swashplate sits perfectly flat against the leveling tool's prongs.
- Verify: Rotate the main shaft slowly to check if the swashplate remains level throughout its rotation. This confirms that there are no binding issues or uneven linkage lengths.
- Remove Tool: Once satisfied with the swashplate level, carefully remove the leveling tool from the main shaft.
