DJI gimbal, GoPro on FPV, HDZero/Walksnail, microSD V30+.

Symptoms

Typical "SD card full" signs in flight, app or OSD:

• SD card full
• Cannot start recording
• Format required
• Test record on ground before flight.

Common causes

Before replacing parts, rule out software, mechanical and environmental causes:

• Forgot to clear before flight
• 4K large files
• Fake capacity card

Tools needed

Prepare before diagnostics — saves time in the field:

• microSD V30/U3
• Microfiber cloth
• Gimbal guard for transport

Step-by-step fix

Work safely: battery off when working on ESC/motors; props removed; after repair — VLOS test flight.

• Format in aircraft before important flight.
• Backup and delete old clips.
• Use genuine V30+ cards.

Additional diagnostics

Test record on ground before flight.

Format SD in aircraft, not PC (FAT32/exFAT).

Shutter 2× FPS — reduces jello.

When to contact service

If any of the following apply — do not fly and contact authorised service:

• Gimbal motor overload after calibration.
• Physical SD slot damage.
• Camera won't focus after impact — service.

Prevention

Prevention reduces failure risk and supports EASA Open / VLOS compliance:

• Format ritual pre-flight

Frequently asked questions

Is it safe to fly with "SD card full"?

No if the fault affects navigation, power, ESC or link. Fix on the ground first, then conduct a VLOS test flight in open area.

How long does diagnosis take?

Most “SD card full” cases — 15–45 min on the ground. Complex ones (firmware, hardware) may need 1–2 h and service.

Must I register repair with the NAA?

No mandatory repair registration, but a maintenance log is recommended for commercial operations.
