500-X4 500mm Carbon Fiber Frame Kit
This frame uses a 3K carbon fiber board and full CNC machining, delivering strong structural integrity for demanding flights. Its folding design enhances portability, making field transport easier for pilots who travel to various locations. The kit is designed to support a porous UAV platform arrangement, enabling flexible payload configurations and accessory mounting. The combination of rigidity and modularity supports stable handling during aerobatic maneuvers and long-range FPV flights.
Readytosky S500 Quadcopter Frame
marketed as an upgrade option for the F450 FPV frame, this 500-class frame uses carbon fiber with a PCB-style center plate for clean wiring and solder points. The design emphasizes high-quality carbon fiber material and fine detailing to minimize weight while preserving strength. The included carbon fiber landing gear contributes to smooth landings and added ground clearance, helping protect sensors and electronics during routine operations.
Readytosky ZD550 Folding Frame
The ZD550 offers a 550mm frame footprint with a compact folding mechanism for easy transport. It uses a main board made from 3K full carbon fiber, delivering a sturdy, lightweight structure suited for high-speed FPV flights and stable cruising. Positive locking folding arms simplify setup and storage, while the frame’s geometry accommodates larger PDBs and flight controllers for more flexible configurations.
295mm FPV Racing Drone Frame
Designed for long-range FPV freestyle, this 7-inch frame uses full 3K carbon fiber to keep weight low while maintaining rigidity under stress. The 5mm arm thickness provides added durability for aggressive maneuvers and occasional crashes. Its geometry supports larger props and efficient propulsion setups, making it suitable for pilots seeking high agility without sacrificing durability.
225mm FPV Racing Drone Frame
Crafted from high-quality 3K carbon fiber with precise CNC processing, this 5-inch freestyle frame emphasizes looks as well as performance. It includes ample space for electronic installation and utilizes 25mm standoffs to optimize height and center-of-gravity. This setup is ideal for pilots who want a compact, maneuverable frame with room for essential FPV components and sensors.
Buying Guide
Key purchase considerations for large carbon fiber quadcopter frames include material quality, frame size, and folding versus fixed designs. For stability and payload capacity, prioritize frames built with 3K carbon fiber and CNC precision. Folding frames excel in portability for field work, while fixed frames may offer slightly better rigidity and rigidity for large batteries and motors. Consider the center plate design, availability of compatible landing gear, and the ease of wiring through PCB-based centers or modular arms.
Other important factors:
- Frame size: 500mm–550mm frames suit heavier propulsion setups and advanced FPV kits; smaller 225mm–295mm frames serve more agile, lightweight builds.
- Armor and protection: integrated landing gear or skid plates help protect electronics during hard landings.
- Weight-to-strength ratio: 3K carbon fiber with CNC machining provides robust frames without excessive weight.
- Portability: folding mechanisms reduce transport volume but may introduce additional joints to maintain rigidity during flight.
- Compatibility: ensure the frame supports your preferred flight controller, ESCs, and power systems, including center plates and mounting patterns.
When evaluating options, balance portability with payload capacity and the intended use — sport freestyle, long-range FPV, or camera-equipped cruising. Reading user reviews and checking compatibility with your control system helps ensure a smoother build process and reliable performance in the air.
