5mm motor spool

My daughter, her friends and myself have having a blast with @271828's Pull String Helicopter. But I had to see if I could take it up a notch. I have a bunch of 2204/2205 brushless motors and ESC's laying around so figured a powered version would be fun.

The Onshape project is here if anyone wants to modify this further:

I'm also working on a modification of the handle to mount the 220x motor on top and hold the electronics.

Right now I'm just using this with a 12a "s
