The DU-BRO Micro Servo Arm XL is designed for pilots who need extra control throw on their micro electric and 3D airplanes. Standard micro servo arms are often too short for high-performance flying, especially when you need fast and dramatic control-surface movement. These extra-long servo arms solve that problem by giving your model more leverage, more throw, and better precision.
Each package includes four single arms and two double arms, giving you options for different setups. All arms measure 1 inch (25.4 mm) from the center to the outer tip, making them long enough to deliver the large control movements required for 3D aerobatics.
The arms are made from 100% virgin nylon, which keeps them extremely strong while still lightweight. This material helps them stand up to the demands of hard 3D flying—snaps, spins, fast transitions, and aggressive rudder work—without bending or losing accuracy. Even with their strength, they remain smooth and precise.
These servo arms are perfect for anyone flying micro 3D airplanes, indoor foamies, park flyers, or lightweight aerobatic models. They deliver the strength, throw, and precision you need for responsive, high-energy flying.
