Notes
- Y6 puts two coaxial motors on each of three arms, giving hex-like lift in a tricopter footprint with no yaw servo (Oscar Liang).
- Coaxial props lose ~10-20% efficiency because the lower prop works in the upper's wash.
- The file is a reference example built by Xem Studio from the numbers above (Illustrative.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.

Why lower efficiency?
Lower prop runs in moved air (Oscar Liang).
