Mark 4 7inch 295mm Arm Thickness 5mm FPV Racing Drone Quadcopter Freestyle Carbon Fiber Frame Kit

The Mark 4 7inch 295mm Arm Thickness 5mm FPV Racing Drone Quadcopter Freestyle Carbon Fiber Frame Kit is a precision-engineered chassis for pilots building high-performance 7" class freestyle and racing quadcopters. Constructed from durable carbon fiber, this frame features 295mm arm spacing and 5mm arm thickness for a balance of stiffness and impact resilience tailored to aggressive flight and maneuvering.

Designed with a straightforward, serviceable layout, the Mark 4 frame provides ample space for common FPV components including flight controllers, ESC stacks, video transmitters and HD cameras. The stack and component mounting areas are organized to support clean wiring and secure fastenings, helping to streamline assembly and maintenance.

Reinforced motor mount areas and rigid plate construction help maintain frame integrity during hard landings and high-G maneuvers. The geometry and layout support a wide range of motor and propeller combinations typical of 7" freestyle setups, while the open structural design allows for effective cooling of electronics during extended flights.

As a carbon fiber frame kit, the Mark 4 emphasizes reliability, predictable handling and long-term durability for pilots focused on freestyle and racing performance.
