Why use eight motors? · Standard part · basis: Design rules and figures from the cited sources; example geometry by Xem Studio

Exact dimensions. True size, with no printing tolerance added.

Notes

Eight motors in one plane give more lift and redundancy than a hex, for heavy filming rigs, but draw more current and cost more (Oscar Liang). It tolerates a failed motor if enough thrust remains (r/multicopter wiki).
The file is a reference example built by Xem Studio from the numbers above (Illustrative heavy-lift frame.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
