RC Spinner

This is an unusual RC spinner that you can not find on the web, maybe I'm the first to create a similar object...why? Because you can use it with the propsaver (this one https://www.hobbyking.com/en_us/3-17mm-prop-saver-set-blue-1pc.html)

I made this spinner for my homemade R/C combat aircrafts but you can print yours and install in your model if it goes well.

Info:
Diameter: 53 mm
Length: 44 mm
Hole: 7mm
Weigth: 16g
Screw: 2x 3mmx9.5mm

I tested the spinner with:
- 1000kv motor
