🔧 Component Overview

The DJI Agras T40 Original Drone Arm Connector is a position-specific structural component designed to connect one of the aircraft’s four primary arm assemblies to the central frame.

This listing allows the customer to select the individual connector required for the:

M1 arm position
M2 arm position
M3 arm position
M4 arm position

Each connector is designed for a specific location on the DJI Agras T40 and supports the proper attachment, alignment, folding operation, and structural positioning of the corresponding aircraft arm.

Because the M1, M2, M3, and M4 connectors may differ in orientation, geometry, mounting configuration, cable-routing clearance, or surrounding-component fitment, it is important to select the correct position for the repair.

The arm connector forms part of the structural interface between the aircraft’s central frame and folding arm assembly.

Although relatively compact, this component supports one of the most important areas of the aircraft. Each arm carries propulsion equipment that must remain securely attached and correctly positioned throughout flight, application, landing, transport, and repeated daily deployment.
