What is a stretched X frame? · Standard part · basis: Design rules and figures from the cited sources; example geometry by Xem Studio

Also called: stretched x, long x frame, racing stretched x, stretch x quad, fpv stretched frame, 6 inch stretched x, stretched vs true x

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

sizes: 2 in table

Notes

A stretched X moves motors further apart front-to-back. Pilots link it to racing and pitch stability at speed (IntoFPV); UAVModel lists reduced yaw and roll vs maximum pitch authority, with props in view.
Unequal spacing gives two arm resonance frequencies, so filtering is more complex (UAVModel).
The file is a reference example built by Xem Studio from the numbers above (Reference 5-inch build: 220 mm diagonal within Grepow's 210-250 mm class for 5 in props.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
