Deadcat frame — dimension sheet

Basis: Design rules and figures from the cited sources; example geometry by Xem Studio
Catalog version: 2026-10-20

Sizes: see table below
- A deadcat spreads the front arms wider and longer than the rear so no props appear in the shot (UAVModel). It exists mainly to keep props out of view, not for racing (IntoFPV).
- Costs: yaw authority falls ~10-15%, two arm resonance frequencies complicate filtering, and pilots report more weight on some builds (UAVModel; IntoFPV).
- 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.

parameter  value or range  source
Yaw reduction  ~10-15%  UAVModel
Suggested roll P vs pitch P  5-10% lower  UAVModel
5 in prop frame size  210-250 mm diagonal (motor to motor)  Grepow
