Heavy Line F413 13” Carbon Fiber FPV Drone Frame

The Heavy Line F413 13” carbon fiber FPV drone frame with a 528mm wheelbase is designed for large-scale builds using propellers up to 13 inches. The 4-arm True-X layout is ideal for powerful FPV platforms where high payload capacity and flight range are top priorities.

Built using 3K pressed carbon fiber with directional fibers, the 8mm thick arms provide structural rigidity for large-format drones and resist deformation under high motor torque. This construction is crucial for 13-inch propellers, reducing the risk of geometric flex under thrust loads, vibrations, and hard landings.

The Heavy Line F413 frame is engineered for heavy FPV setups requiring a reinforced base and broad motor compatibility. Dimensions of 445 × 400 × 45 mm offer ample room to arrange core electronics and auxiliary equipment. Weighing 450 g, this frame weight should be factored in when selecting motors, battery packs, and build components.

The mounting base supports 30.5 × 30.5 mm (M3) and 20 × 20 mm patterns. The frame is compatible with 35xx and 42xx size motors. Motor mounting size is Ø27–Ø30 mm, secured via four M4 screws. Verify motor mounting hole patterns before installation.
