Robu F450 F550 Q450 Q550 Replacement Arm Black 220mm

This replacement arm is crafted from high-quality PA66 Polyamide Nylon, significantly reinforced with approximately 35% glass fiber. This composite material blend dramatically enhances its structural integrity, providing superior resistance to impacts and wear compared to standard plastics. The glass fiber content specifically increases stiffness and tensile strength, crucial for drone frame components.

This Robu replacement arm is engineered for direct compatibility with several popular multirotor drone frames. It is a perfect fit for the F450, F550, Q450, and Q550 series frames. Its precise dimensions ensure seamless integration, allowing for straightforward repairs and maintaining the original flight dynamics of your quadcopter or hexacopter.

The addition of glass fiber reinforcement significantly improves the arm's mechanical properties. It provides enhanced rigidity, preventing unwanted flex during aggressive maneuvers, and increases resistance to fatigue, ensuring longevity under repeated stress. This reinforcement also contributes to better vibration damping and improved overall stability, translating to a more reliable and responsive flight experience.

Installation of this replacement arm is designed to be straightforward for drone builders. It features standard mounting points and a precise form factor, ensuring a direct bolt-on fit without modifications. Typically, you only need to remove the damaged arm, detach the motors and ESCs, and then secure the new arm using the existing hardware.

This replacement arm is designed with a lightweight profile, weighing just 50 grams. Its material composition (Polyamide Nylon with glass fiber) provides excellent strength-to-weight ratio. When installed, it maintains the drone's intended weight balance and aerodynamic properties, ensuring that flight performance, including agility and stability, remains consistent with the original frame design.
