# Hybrid X frame

> What is a hybrid X frame?

- Category: Drone design › Drone frame layouts
- Kind: Standard part
- Basis: Design rules and figures from the cited sources; example geometry by Xem Studio
- Page: https://xemstudio.com/objects/hybrid-x-frame/ · JSON: https://xemstudio.com/api/geometry?object=hybrid-x-frame · Plain text: https://xemstudio.com/objects/hybrid-x-frame/sheet.txt

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

## Notes

- UAVModel describes hybrid X as a 'moderate deadcat' between true X and deadcat: minimal props in view with near-symmetric roll and pitch and slightly reduced yaw.
- 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.

## Sizes

| parameter | value or range | source |
|---|---|---|
| Prop view | minimal props | UAVModel |
| 5 in prop frame size | 210-250 mm diagonal (motor to motor) | Grepow |

**Good all-rounder?**

UAVModel calls it the all-around compromise.
