Compact printing
Top, bottom, coupler and avionics sled are sized to fit a 256 mm printer.
Peregrine Mini · Open-source engineering
The smaller sibling, designed around 5-inch props.
A compact open-source VTOL FPV tail-sitter with the Peregrine family shape, a bought clear camera dome and a removable avionics sled. Designed around parts that fit a 256 mm printer.

Design, document, share
CAD, electronics and software in one project.
The Mini keeps the curved root fairings, tapered wings and swept canards in a smaller airframe, with short tapered motor pods. The top and bottom join through a keyed twist-lock coupler, while a removable sled carries the electronics. The short pods are not landing feet: an upright launch support is required and is not included in the CAD files.
Motor-lead routes have been modelled and interference-checked. The Mini has no airflow study or flight-test results yet, and the VTX antenna position remains an open design item.
Developed with CAD and AI-assisted design tools, and shared for hobby makers to study and develop. Both versions are unbuilt designs awaiting physical validation.
Inside the design
Practical details, openly documented.
Serviceable electronics
A removable sled gives access to the flight-controller stack and receiver.
Camera and GPS
A pivoting camera cradle and GPS shelf sit beneath a bought clear dome.
Documented routes
The repository includes STEP files, a bill of materials and motor-lead routing notes.
