Helicopter Toy (scale fixed)

This is a remix of this helicopter toy with corrected part orientations and the scale of each part fixed. I'm still trying to figure out a sensible modification to the ripcord because it's difficult to print as-is.

Every print must include the blades and the ripcord. The body of the helicopter can either be printed in a single piece (helicopter-unibody) or as three separate pieces glued together (helicopter-base, helicopter-front, helicopter-cockpit-window). All body parts can be printed without supports.

I've also included an alternative version of the tail (helicopter-tail-truncated) that's significantly easier to print, at the expense of matching the body perfectly. The simplest overall print for the full helicopter would be to print helicopter-blades, helicopter-unibody, and helicopter-tail-truncated. No supports are necessary for these three parts.
