Coaxial Multi-Rotor Arm -- Version 1

Design in progress... Things will be changing...

I'm designing a simple coaxial motor mount for a multirotor, using a couple of dirt cheap 2212 motors and other inexpensive components to make a reliable arm that can be used for a Y-6,X-8, or other configurations.

The carbon fiber arm is 10mm OD, and I'm using a 500mm length.

I am also mounting a strip of ws2812b LEDs on the inside of the motor housing, and using a translucent grey ABS for the light to pass through. Test video: https
