RC plane two, three and zero blade propeller spinner - clockwise and counter-clockwise

thingiverse

This clever adaptation of Aero330's spinner leverages his ingenious tongue and groove method, but dispenses with the open slot for screws that often proved troublesome. The tiny screws had a tendency to slip inside the spinner before I could secure them properly within the locating holes. This design relocates the screw holes to the exterior rim of the spinner, resulting in a neater finish. A clockwise and counter-clockwise version is available for twin-engine planes. The conventional choice would naturally be the counter-clockwise one. March 2018 I've recently expanded the collection with three-bladed and zero-blade versions. Due to the original CAD files' somewhat haphazard nature, the three-bladed and zero-blade designs have been reworked - the three-bladed model in Sketchup and the zero-bladed version in Fusion 360 (which I now prefer for my modeling needs). I'll tidy up all the variations in due course.

Then, secure the parts together using the screws provided with servos once they're positioned on the prop shaft.
