APEX HD 5-inch 225mm FPV Carbon Fiber Frame:

Material: The frame is likely constructed from carbon fiber, known for its lightweight yet durable properties. Carbon fiber is a popular choice for FPV (First Person View) drone frames due to its ability to withstand crashes and reduce vibration.

Size: The frame is designed to accommodate 5-inch propellers, indicating the size of the propeller blades. The 225mm measurement likely refers to the diagonal motor-to-motor distance, providing an idea of the overall size and maneuverability of the drone.

Design: FPV frames often feature aerodynamic designs to enhance speed and agility. The APEX HD frame may have a sleek and compact design, possibly with a unibody or modular construction for ease of maintenance and repairs.

Compatibility: The frame is likely designed to be compatible with standard FPV components, including flight controllers, motors, ESCs (Electronic Speed Controllers), FPV cameras, and video transmitters. The "HD" in the name suggests that it may be specifically designed to carry HD cameras for high-quality recording.

Weight: While the frame needs to be sturdy, FPV frames often aim for a balance between durability and weight to ensure agility and responsiveness. The carbon fiber construction helps keep the weight relatively low.
