Propeller mount for Zipper

About the project : The factory motor and propeller of this RC plane really suck, so I decided to modify this by upgrading the propeller and the motor to something better (see parts list below). I designed the part to mount the propeller on the motor in Fusion360. This was a cheap but effective alternative to the common aluminium spinners/mount. It uses the screw holes which were present on the motor, so the build is really strong and really compact.

The airplane flies well with this mod, and the printed parts seem to be crash-proof (at least until now)

PARTS :
- Model : Hitec Zipper
- Motor : EFlite EFLUM1808L2 2500KV
- Propeller : APC 4.5x4.1 E Speed 400
