Note: this listing is for ONE arm in your selected position. Positions must match your aircraft layout — if you need help confirming the correct arm, verification against the DJI parts diagram is required.

🔧 Component Overview

The DJI Agras T100 Original Drone Arm is a primary load-bearing structural component of the aircraft. Each arm (M1, M2, M3, M4) is engineered to manage extreme torsional forces generated by high-torque motors, large propellers, full payloads, and long-duration spray or spreading missions.

This is not a cosmetic component. A compromised arm directly affects thrust alignment, vibration control, flight stability, and long-term motor and ESC health. For commercial operators, arm integrity is non-negotiable.

⚙️ Functional Purpose

Each arm integrates:

• Motor mounting interface
• Internal power and signal routing
• Structural load transfer between frame and propulsion system

Under real-world agricultural use, arms absorb:

• Continuous vibration from high-RPM motors
• Dynamic load shifts from liquid or granular payloads
• Stress from takeoffs, landings, and uneven terrain

⚠️ Common Replacement Indicators

• Deformation, micro-cracking, or impact damage at any arm
• New vibration or motor misalignment at one position
• Hard landing, rollover, or transport damage
• Frame asymmetry found during routine inspection

Any deformation, micro-cracking, or impact damage must be addressed immediately to avoid cascading failures.

📐 Specifications

• Component Type: Aircraft arm (structural propulsion mount)
• Compatibility: DJI Agras T100
• Positions: M1 / M2 / M3 / M4 (must match aircraft layout)
• Construction: Reinforced aluminum alloy with integrated mounting geometry
• Installation Location: Main airframe – propulsion arms

Inspect before installation:

• Confirm you ordered the correct position (M1–M4) for the motor you are replacing
• Confirm the new arm is true and free of shipping damage
• Inspect the frame joint and adjacent hardware for hidden impact damage

After installation:

• Torque all fasteners to spec and route power/signal lines per factory channels
• Check motor alignment and propeller clearance by hand before power-up
• Run an unloaded hover test, then a partial-load test, before full-payload missions

🚜 Necessary For

This is a required inventory item for:

• Commercial spray operators running the T100 at scale
• Fleet owners managing multiple aircraft
• Repair centers servicing post-impact or high-hour airframes
• Operators preparing for peak spray season with zero downtime tolerance

Professional operators do not wait for an arm failure mid-season.

💡 Why OEM Arms Matter

Non-OEM or repaired arms introduce:

• Thrust misalignment
• Accelerated motor bearing wear
• ESC thermal stress
• Flight instability under load

Replacing an arm restores factory geometry, preserves propulsion balance, and protects significantly more expensive downstream components.

Match the position. Restore the geometry. Balance the thrust. Fly the T100 factory-true.
