Craycle SF-Spinner V4, Screw-Free 3D Printed Propeller Spinner

Craycle SF-Spinner V4 is a screw-free 3D printed propeller spinner designed for RC aircraft. It is lightweight, strong, easy to print and simple to assemble.

This spinner was originally developed for Craycle RC models, but it can also be used on your own RC aircraft projects. With multiple sizes and blade options included in one product, you can easily access the latest versions and updated files whenever new sizes are added.

Screw Free Spinner Design

The Craycle SF-Spinner V4 uses a screw-free connection system. This helps reduce vibration and makes the assembly process much cleaner.

To install the spinner, place the base part onto the motor shaft after the propeller. Then tighten the motor nut and install the spinner cap. No extra screws are needed.

What Is New in Spinner V4?

Spinner V4 includes several important improvements compared to the previous versions. V2 and V3 had a similar design concept, but V4 improves strength, balance, printability and the connection system.

The biggest improvement is the symmetrical design. There are no separate CW and CCW versions anymore. This also removes confusion between pusher and puller motor setups.

Main Improvements

• No separate CW or CCW rotation versions anymore
• Symmetrical design for easier use
• 2 blade, 3 blade and multi blade options included
• Improved spinner balance
• Stronger cap thread design
• Better spinner pressure and connection
• Easier assembly
• Common slicer settings for all options
• Easier and cleaner 3D printing process
