DJI Matrice 4T Middle Shell

Description

DJI Matrice 4T Middle Shell

The Original Middle Shell for DJI Matrice 4T is a genuine OEM replacement accessory designed specifically for the DJI Matrice 4T and 4E enterprise drones. It serves as a critical structural component of the drone’s body frame, providing the central housing that supports the motors, battery, gimbal, and other internal electronics. This part is essential for repairs after damage from impacts, wear, or accidents, helping to restore the drone’s aerodynamic integrity, vibration resistance, and overall stability. Made from high-quality, durable materials, it ensures seamless compatibility without compromising the drone’s IP rating or flight performance. As a “new” item, it comes directly from DJI’s supply chain, making it ideal for professional users in inspection, surveying, or public safety applications.

Key Features

• Genuine DJI Quality: Authentic OEM part for perfect fit and reliability, preventing issues like misalignment or reduced performance seen with third-party alternatives.
• Compatibility: Fully compatible with DJI Matrice 4T (thermal imaging model) and 4E (visual surveying model), supporting the series’ compact design for enterprise use.
• Structural Restoration: Replaces the middle frame to maintain the drone’s lightweight yet robust build, weighing approximately 1.43 kg (full aircraft MTOM), with enhanced durability against environmental stresses.
• Comprehensive Kit Options: Often bundled with upper shell, battery cover, gimbal protector, and fixed covers for complete body repair, ensuring full structural recovery.
• Easy Integration: Precision-engineered for quick snap-fit or screw assembly, preserving the drone’s advanced features like omnidirectional obstacle sensing and RTK positioning.

How to Use 

Installation of the middle shell requires basic tools like a screwdriver set and anti-static wrist strap to avoid damaging electronics. Follow these general steps based on DJI’s maintenance guidelines (always refer to the official Maintenance Manual for visuals):

1. Preparation: Power off the drone, remove the Intelligent Flight Battery, and disconnect any payloads or accessories. Work in a clean, static-free environment.
2. Disassembly: Fold the arms inward, remove propellers (counter-clockwise for CW motors), and unscrew the upper shell or covers to access the middle frame. Gently detach connected cables (e.g., from motors or gimbal) without pulling wires.
3. Replacement: Align the new middle shell with mounting points, secure with provided screws (torque to 0.4-0.6 Nm to avoid stripping), and reconnect all cables securely. Ensure no gaps or loose parts.
4. Reassembly: Reinstall propellers (clockwise for CW motors until they click), battery, and any covers. Perform a pre-flight calibration via DJI Pilot 2 app to verify sensors and balance.
5. Testing: Power on, check for error codes, and conduct a low-altitude hover test in an open area.

How to Care

Proper care extends the lifespan of the middle shell and overall drone:

• Cleaning: Wipe with a soft, dry microfiber cloth after each flight to remove dust or debris. For stubborn marks, use a mild, non-abrasive cleaner (no alcohol or solvents). Avoid water exposure, as the drone is not fully waterproof.
• Storage: Store in a cool, dry place (22°–28°C) away from direct sunlight or humidity. Keep arms folded and battery removed; inspect for cracks quarterly.
• Inspection: Before flights, check for dents, loose screws, or wear. Update firmware regularly via DJI Pilot 2 to ensure compatibility.
• Battery Integration: Since the shell interfaces with the battery compartment, always cool batteries post-flight before storage and charge to 50% for long-term inactivity.
• General Tips: Avoid impacts by using protective cases during transport; replace if any structural deformation occurs.

Safety

Safety is paramount when handling or installing the middle shell to prevent injury or drone malfunction:

• Handling Precautions: Wear protective gloves to avoid cuts from sharp edges; never operate near people, animals, or sensitive areas like airports without permits.
• Flight Restrictions: Adhere to GEO zones in DJI Pilot 2—avoid restricted areas and maintain visual line of sight (VLOS). Do not fly in rain, high winds (>8 m/s), or low light (<10 lux) where vision systems may fail.
• Installation Warnings: Disconnect power sources before work; improper assembly can cause imbalance, leading to crashes. Calibrate all systems post-installation.
• Battery Safety: Handle batteries carefully—the shell’s compartment design minimizes risks, but store in fireproof bags and discharge to <30% for air travel.
• Regulatory Compliance: Follow local laws (e.g., FAA C2 certification for <1.43 kg drones); enable Remote ID and AirSense for collision alerts from manned aircraft within 10 km.
