Seven-inch is the long-range FPV size: efficient cruise on mid-size motors, and lift for mid-size multirotors. The line covers it in a tri-blade for platforms that want grip and a bi-blade for platforms that want range, each referenced to the Gemfan Flash part it replaces.
Material follows application, not size: glass-fiber-reinforced PA66 where a platform needs stiffness under load, polycarbonate where it needs impact survival and low rotational mass. Several sizes are offered in both.

Each SKU is referenced to the foreign part it is built to drop in for. If the part number on your BOM is here, the Anvil size is the domestic replacement; if it isn't, check the full cross-reference or send us the number.
Send the part number on your BOM with your quantity, NDAA requirement, and timeline. Anvil Propulsion will tell you straight whether it's in the line, and other configurations are handled as custom programs.
