Introducing RotorForge v0.37.0: FreeCAD Workbench for FPV Frames

RotorForge v0.43.0 — a FreeCAD workbench for designing FPV frames

Hey everyone,

I’d like to share something I’ve been working on: RotorForge, a FreeCAD workbench for designing custom FPV drone frames.

The idea is to bring the main frame dimensions and mounting options into one editor. You can adjust your design, preview the layout, generate an editable 3D model, and export DXF/SVG cutting profiles.

The current version includes:

True X, Stretched X and Deadcat layouts

Two-plate and three-plate designs

Adjustable arms, arm roots, mounting bolts and motor-pad shapes

Three-hole and four-hole motor mounting patterns, with independent hole rotation

Camera mounting with adjustable tilt, plus stack, standoff and VTX mounting options

Battery strap slots, airflow openings and plate outline cutouts

Settings saved as JSON so designs can be shared and edited later

The latest update adds mirrored motor-pad rotation, with a choice of rotating around the motor centre or the beginning of the pad. The arm connection follows the rotated pad to keep the geometry connected.

It’s still being developed, and I’d appreciate feedback from people who design or build their own frames. Bugs, awkward controls, missing options, or practical issues you spot in the generated designs would all be useful.

Let me know what you think!
