Airframe Arm with High-Torque Brushless Motor Compatible with Matrice 4T / 4E Series

Restore certified physical skeletal rigidity and original dynamic rotational lifting torque to your industrial fleet with this premium replacement airframe arm with pre-installed high-torque brushless motor, precision-engineered to exact Matrice 4T and Matrice 4E enterprise blueprints. Designed specifically for advanced drone tech maintenance centers and fleet engineers who intend to reuse or separately source the electronic speed controller (ESC), this integrated structural arm block eliminates the difficulty of press-fitting the motor housing manually onto the composite tube.

IMPORTANT COMPONENT NOTE: This assembly includes the high-tensile composite arm linkage structure, quick-release propeller adapter hub, and the factory-spec heavy-duty brushless motor with pre-routed phase leads. The internal Electronic Speed Controller (ESC) board is NOT included and must be transferred from your donor airframe or sourced independently.

Key Features & Benefits:

• Factory-Aligned Motor Seating: The high-kv industrial brushless motor is pre-pressed and micro-milled straight onto the carbon-fiber composite arm frame at the factory, ensuring absolute axial zero-tilt alignment to eliminate chronic high-RPM bearing vibrations.
• Aviation-Grade Carbon-Composite Tube: Engineered to endure severe structural cross-shear vectors, dynamic wind-loading spikes, and sudden kinetic impacts during critical mapping or tactical operations.
• Open-Ended Phase Wire Leads: Features high-grade, heat-insulated motor phase wires pre-routed through the arm joint pivot cavity, ready for clean, low-resistance soldering directly onto your existing ESC terminal pads.

The premier cost-effective internal hardware maintenance choice for commercial survey groups, government drone service centers, and specialized third-party UAV electronics repair labs looking to replace warped motor shafts, gritty bearings, or cracked arm segments without buying redundant full-electronics blocks.

Every single arm with brushless motor housing undergoes a rigorous 100% geometric profile symmetry verification, phase resistance continuity analysis, and internal bearing friction clearance sweep before shipping to guarantee absolute flight readiness on your workbench, backed by our 30-day functional warranty.
