Robu F450 F550 Q450 Q550 Replacement Frame Arm (White, 220mm)

This replacement arm is meticulously crafted from a robust blend of Polyamide Nylon (PA66) and approximately 35% glass fiber. This composite construction significantly enhances the arm's structural integrity, providing superior strength, impact resistance, and durability. The glass fiber reinforcement prevents flex and ensures long-term reliability under various flight conditions, crucial for demanding multirotor applications.

Yes, this replacement arm is engineered for precise compatibility with F450, F550, Q450, and Q550 multirotor drone frames. Its dimensions (220x40mm) and 3mm motor mounting holes perfectly match the original specifications, ensuring a direct and hassle-free replacement. This design maintains the drone's original geometry and balance, which is vital for stable and predictable flight performance.

Utilizing a glass fiber reinforced arm offers significant advantages in drone repair. The added glass fiber dramatically increases the arm's tensile strength and rigidity, making it less prone to breaking upon impact compared to standard nylon arms. This enhanced durability extends the lifespan of your drone, reduces recurring repair costs, and ensures a more resilient airframe for aggressive flying or demanding operational tasks.

Weighing only 50 grams, this replacement arm is designed to be lightweight, minimizing any adverse impact on your drone's overall performance. A lighter arm contributes to maintaining the drone's power-to-weight ratio, which is essential for agile flight, efficient power consumption, and extended flight times. This ensures your multirotor retains its dynamic capabilities without unnecessary added mass.
