Martian-II 220mm Quadcopter Frame Replacement Arm

This replacement arm is engineered exclusively for the Martian-II 220mm quadcopter frame. Its dimensions and mounting points are precisely aligned to ensure a direct and secure fit. Using it with other frames may result in improper alignment, compromised structural integrity, or require modifications not recommended for optimal flight performance and safety.

Carbon fiber offers an excellent strength-to-weight ratio, crucial for FPV drone components. It provides high rigidity and impact resistance, essential for surviving crashes common in freestyle and racing. This material choice minimizes added weight to the frame while maximizing durability, ensuring the drone maintains its agile flight characteristics and structural integrity over time.

The 4mm thickness of this carbon fiber arm provides significant resistance to bending and breakage upon impact. While thicker than some lighter race frames, it strikes an optimal balance for freestyle and general FPV flying, where durability is paramount. This thickness helps distribute stress more effectively, safeguarding critical components and extending the lifespan of your quadcopter frame.

Installing this replacement arm is straightforward. You will typically need to remove the mounting screws securing the damaged arm to the main frame plate. Carefully detach the old arm, ensuring any motor wiring is disconnected. Then, align the new carbon fiber arm with the frame's mounting holes and secure it with the appropriate screws. Reconnect motor wires if necessary, then perform a quick check.
