Product Description:
Upgrade and maintain your agricultural drone with this premium arm joint — meticulously engineered for the EFT E-series frame, specifically the model E616P (also compatible with certain E416P/E410P variants). This high-quality component ensures structural integrity, stability in flight, and long-term durability essential for high-payload agricultural missions.
Key Features & Benefits
Perfect Fit & Compatibility: Designed for the E616P series and compatible frames with 40mm arm diameter (φ40) — ensures seamless integration with the drone’s folding arm mechanism built into the EFT E-series agricultural platforms. rcdelhi.in+2Indian Robo Store+2
Robust Material & Construction: Engineered using high-strength composite and injection-moulded materials, replacing traditional aluminium in newer EFT arms for improved durability, reduced sagging, and enhanced resistance in rugged field environments. c.effort-tech.com+1
Folding Arm Mechanism Support: Supports the folding arm design integral to the E616P’s transport- and field-ready architecture, enabling compact storage and easier deployment. DrUAV+1
Precision Engineering: With exact dimensions (φ40/4037315) and pre-drilled mounting holes, this arm joint ensures firm alignment with the drone’s hub and fuselage — critical for balanced flight and structural integrity. Indian Robo Store
Easy Maintenance & Swap-out: Designed for straightforward replacement of worn or damaged arms — reducing downtime in your agricultural operations and avoiding costly full-frame replacements.
Optimised for Agriculture Applications: Built with the performance demands of heavy-payload agricultural spraying frames in mind (such as 16 L capacity and 35 kg take-off weights on E616P frames). DrUAV+1

Why This Part Matters in Your Drone System
In agricultural drones like the E616P, each of six arms carries a motor-propeller unit and experiences significant aerodynamic force, payload weight, and vibration stress. A compromised arm joint can lead to vibration, misalignment, unstable flight, or even structural failure. Replacing worn or damaged arms with high-quality assemblies preserves:
Frame rigidity and alignment
Vibration control (improves motor and ESC lifespan)
Propeller balance and thrust symmetry
Safe folding/unfolding for transport and field use
Long-term reliability and reduced maintenance costs
Ideal Use Cases
Field operators and ag-tech companies using the EFT E616P in spraying, seeding, fertilising operations
Maintenance workshops servicing EFT-series drones and needing genuine-fit arm assemblies
DIY drone integrators building or restoring EFT frames with exact replacement parts
India-based ag-drone fleets requiring locally available spares (fits your website’s audience in Andhra Pradesh and India at large)
Installation & Maintenance Tips
Remove the affected arm assembly by loosening the mounting bolts and unplugging any wiring harnesses (if arm includes wiring for motor/ESC).
Ensure the hub mounting surface is clean, free of debris and checked for damage.
Align the new arm joint precisely, torque bolts to manufacturer’s specification, and verify that the folding mechanism operates smoothly (no binding or play).
Re-balance the propeller and rotor assembly after installation to maintain vibration within safe limits.
After installation, conduct a hover test with no payload, then a loaded test to confirm stability.
Regularly inspect folding joints, bolts and fixing clips for signs of wear — especially given the harsh field environment (dust, moisture, chemicals) in agricultural use.
