1. Gather Necessary Tools and Parts:
- Screwdriver (usually Phillips head)
- Replacement Propeller Shaft
- New Propeller (if the shaft and propeller come separately)
- Small pliers or tweezers
2. Start Disassembly:
- Remove the propeller by gently pulling or twisting it off the shaft while holding the motor.
- Use a screwdriver to remove the screws holding the propeller shaft in place.
3. Inspect the Assembly:
- Carefully examine the old propeller shaft for any damage like bends or cracks.
- Check the motor mount for damage and ensure it is secure.
4. Remove Shaft:
- Once the screws are removed, you should be able to slide the old propeller shaft out from the motor mount.
- Take note of any O-rings or washers on the shaft that need to be transferred to the new shaft.
5. Install the Replacement Propeller Shaft:
- Slide the new propeller shaft into the motor mount.
- Make sure it fits snugly and align it properly with the motor.
6. Reattach the Propeller:
- If you purchased a replacement propeller, slide it onto the new shaft.
- If you are reusing the old propeller, place it back onto the shaft.
- Ensure that the propeller is properly seated and secured on the shaft.
7. Replace Screws:
- Use the screwdriver to replace the screws you removed in step 2.
- Tighten them securely, but avoid overtightening.
8. Test the Motor:
- Once everything is in place, test the motor by turning it on and confirming that the propeller spins smoothly.
That concludes the general steps for changing a propeller shaft on a Champ RC aircraft. Always refer to your specific RC aircraft's manual or product guide for any model-specific instructions or nuances.
