Overview
The RATEFPV L40 Pro is a 4-inch freestyle FPV frame kit built around a modular carbon-fiber structure for freestyle and lightweight cinematic quad builds. Its separated arm and bottom-plate design allows a damaged arm to be replaced individually, simplifying maintenance. The frame combines 3.6mm carbon-fiber arms with a CNC-machined aluminum camera cage and DC geometry.
