Key Features

Upper Top Shell (Top Cover)

• Front Vision Cutout: Precision‑aligned opening for the forward obstacle‑sensing module.

• GPS / GNSS Mount Point: Integrated mounting bosses for the top‑side GPS antenna assembly.

• Heat‑Dissipation Grille: Matches original airflow channels to maintain FC/ESC cooling.

• Protective Role: Shields the upper mainboard, IMU enclosure and core avionics from impact/debris.

Middle Frame (Main Internal Chassis)

• Load‑Bearing Skeleton: One‑piece injection‑molded structure — the central backbone of the airframe.

• FC / ESC Mounting: Pre‑positioned screw columns for flight controller, ESCs, and power distribution.

• Battery Bay Interface: Exact latch‑point alignment for the smart battery lock mechanism.

• Arm Pivot Anchors: Reinforced hinge mounts for all 4 folding arm assemblies.

• Cable Management: Molded routing channels + clip anchors for ribbon / coaxial flex cables.

Bottom Shell (Lower Cover)

• Downward Vision / ToF Cutout: Pre‑formed window for the bottom obstacle‑sensing & ranging module.

• Gimbal Mounting Base: Precision docking point for the 3‑axis gimbal cradle / damping plate.

• 4G Module Bay (Optional Variant): Cutout for DJI Cellular Dongle / 4G expansion module housing.

• Cooling Airflow: Bottom vent pattern matches OEM ducting for fan‑assisted thermal management.

• Landing Protection: Reinforced skid zones to absorb touchdown impact.

Usage / Repair Tips

• Battery First: Always remove the intelligent flight battery before disassembly.

• Label Cables: Photograph / tag flex cables before unplugging — Mavic 4 Pro has multiple coaxial ribbons (gimbal / vision / GPS).

• Screw Map: Keep original screws organized by location — different posts use different lengths.

• Torque Light: Tighten to finger‑snug + ¼ turn — over‑tightening cracks polymer bosses.

• Post‑Build Calibration: After shell replacement, run Gimbal Calibration + Compass + IMU in DJI Pilot 2 / Fly App before first flight.

• Seal Check: Ensure vision‑sensor windows align perfectly — misalignment triggers obstacle‑sensing errors.

️ Important Notes

• Mavic 4 Pro ONLY: Not compatible with Mavic 3 / 3 Pro / 3 Classic / Air 3 / Mini series — different internal layout.

• Shell‑Only: These are structural covers — electronics, gimbal, battery, screws and seals are NOT included.

• Professional Install Recommended: Internal disassembly exposes delicate flex cables; inexperienced handling risks IMU/gimbal damage.
