Notes

X8 puts a coaxial pair on each arm of an X: more lift and redundancy in a compact, foldable footprint, at a coaxial efficiency penalty of ~10-20% (Oscar Liang).
The file is a reference example built by Xem Studio from the numbers above (Illustrative; true X with coaxial pairs.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
