Multicopter parts

I made some parts to combine to a Multi-Copter.
With these parts is possible to build a simple Tri V-tail, a Tri with negative V-tail or a Spider Hex.
I will design new parts and upload it. The next part will be the plates for a Quad stile multi-copter. And a drive gear to make a real Tri. This will be a challenge.

Update parts:
- Leg Base
- Leg Plate
- T-Couple (60)
These parts are update for a better fit of the nut. The space between the center and edge of the M3 nuts is gone from 2.5mm to 2.75mm.
