Product Introduction
Part No.: 02‑001‑11140 The motor‑end arm is a key load‑bearing structural component, connecting the fuselage and power motor assembly. It bears huge tension and vibration during full‑load spraying and spreading missions. Collision, hard landing and fatigue wear may cause bending, cracks or deformation. Replacing damaged motor‑end arm restores flight stability, avoids abnormal shaking and eliminates potential crash risks.
Technical Parameters
Part Number: 02‑001‑11140
Product Name: Motor‑End Arm
Material: High‑strength lightweight alloy
Installation Position: Outer section of drone arm, mounting position for motor and propeller
Function: Support motor assembly, transfer power load
Replacement Type: Direct OEM replacement, no modification required
Product Uses
Repair after drone collision or hard landing
Routine inspection and overhaul for agricultural drones
Troubleshoot abnormal shaking, tilting during flight
Spare stock for drone repair shops & farm maintenance
Replace bent, cracked or fatigued original arm
Q1: What risks will a deformed motor‑end arm bring?
A1: Bent or cracked motor‑end arm causes unbalanced rotation, severe vibration, tilting flight, and even motor falling‑off in serious cases.
Q2: Is motor‑end arm compatible with 机身‑end arm?
A2: They are different structural parts and cannot be interchanged. Please confirm part number before purchasing.
Q3: Can I bend and repair the deformed arm for reuse?
A3: Not recommended. Internal metal fatigue exists after deformation. Repaired arms have hidden safety hazards and must be replaced directly.
Q4: Do I need to replace accessories together?
A4: Check motor mount, screws and gaskets during replacement; replace worn accessories at the same time.
Product Operate Guide
Power off drone and remove battery for safety.
Remove propeller, motor and related wiring connectors.
Take out fixing screws and dismount the damaged motor‑end arm.
Clean mounting position, remove dust and debris.
Install new 02‑001‑11140 motor‑end arm, tighten all screws with standard torque.
Reinstall motor, connect cables correctly, mount propeller assembly.
Manual check for firm connection, perform ground test before formal flight.
Installation Tip: Do not use damaged screws. Ensure wiring is not squeezed by the arm structure.
