1. Introduction
This instruction manual provides essential information for the proper installation, operation, and maintenance of your HobbyZone Spinner Mini Cub (Model 4808). This component is designed to enhance the aerodynamic performance and aesthetic appeal of compatible remote-controlled aircraft, specifically the Mini Cub model. Please read this manual thoroughly before installation to ensure safe and correct usage.
2. Product Overview
The HobbyZone Spinner Mini Cub is a conical cap that covers the propeller hub and motor shaft on your RC aircraft. Its primary functions include:
- Aerodynamic Efficiency: Reduces drag by providing a smooth transition from the fuselage to the propeller blades.
- Propeller Protection: Shields the propeller hub and mounting hardware from debris and minor impacts.
- Aesthetic Enhancement: Contributes to the scale appearance of the aircraft.

3. Setup and Installation
Proper installation of the spinner is crucial for safe and efficient flight. Ensure your aircraft is powered off and the battery is disconnected before proceeding.
Required Tools:
- Small Phillips head screwdriver (if applicable for propeller retention)
- Wrench or pliers (if applicable for propeller nut)
Installation Steps:
- Prepare the Aircraft: Ensure the aircraft's power system is completely disarmed. Remove the propeller if it is already installed.
- Install the Propeller: Mount the propeller onto the motor shaft according to your aircraft's specific instructions. Ensure it is oriented correctly (leading edge forward) and securely fastened. Tighten any propeller nuts or screws firmly but do not overtighten.
- Position the Spinner: Carefully slide the HobbyZone Spinner Mini Cub over the propeller hub and motor shaft. The spinner should fit snugly against the propeller and the front of the motor mount. Ensure the cutouts on the spinner align with the propeller blades.
- Secure the Spinner: Depending on your specific propeller and motor setup, the spinner may be secured by the propeller nut itself, or it may have small screws that attach it to a backplate (not included with this spinner, typically part of the propeller assembly). Ensure the spinner is firmly seated and does not wobble.
- Final Check: Gently rotate the propeller by hand to ensure the spinner does not rub against any part of the aircraft or propeller blades. Verify that all fasteners are tight.
4. Operating Considerations
Once installed, the spinner requires minimal operational input. However, observe the following:
- Pre-Flight Inspection: Always check that the spinner is securely attached and free from damage before each flight.
- Vibration: Excessive vibration during motor operation can indicate an improperly balanced propeller or spinner, or a loose spinner. Address any vibration issues immediately to prevent damage to the motor or airframe.
5. Maintenance
Regular maintenance ensures the longevity and performance of your spinner.
- Cleaning: Wipe the spinner clean with a soft, damp cloth as needed to remove dirt, dust, or oil residue. Avoid harsh chemicals that may damage the material.
- Inspection: Periodically inspect the spinner for cracks, dents, or other signs of wear or damage. Pay close attention to the areas where it contacts the propeller blades and the motor mount.
- Secure Fit: Ensure the spinner remains tightly secured. If it becomes loose, re-tighten any retaining screws or nuts.
- Replacement: If the spinner is significantly damaged or causes excessive vibration, replace it with a new HobbyZone Spinner Mini Cub (Model 4808).
6. Troubleshooting
Common issues and their solutions:
- Spinner is loose or wobbles:
- Check if the propeller nut or retaining screws are sufficiently tightened.
- Ensure the spinner is correctly seated against the propeller and motor mount.
- Inspect for damage to the spinner or propeller that might prevent a secure fit.
- Excessive vibration during motor operation:
- Verify the propeller is balanced.
- Ensure the spinner is balanced and not damaged.
- Re-check spinner installation for proper alignment and tightness.
- Inspect the motor and motor mount for any issues.
- Spinner does not fit:
- Confirm that you have the correct spinner (Model 4808) for your HobbyZone Mini Cub aircraft.
- Ensure the propeller is correctly installed and not obstructing the spinner's fit.
