Mark4 V2 7" Frame

Mark4 V2 is a 7-inch long-range FPV frame for pilots building a larger-prop freestyle or cruising setup with a compact, modular carbon layout. It pairs a 295 mm wheelbase with 6 mm arms, and the frame supports both 19 mm and 20 mm camera mounts, so it suits common analogue and HD micro camera installs without extra fabrication.

Key features

• Built for 7-inch propellers with a 295 mm wheelbase for stable high-speed cruising and long-range tuning.

• 6 mm arms add stiffness for heavier builds and help reduce flex under load.

• Supports 30.5 x 30.5 mm and 20 x 20 mm stack mounting, giving you room for standard FC and ESC combinations.

• Camera fitment covers both 19 mm and 20 mm sizes, which matches many FPV micro cameras.

• Motor mounting supports 16 x 16 mm and 19 x 19 mm patterns for wider motor compatibility.

• Carbon fibre plates and included hardware make it a straightforward base for a custom 7-inch build.
