The DJI FlyCart 30 is IP55 rated.

The protection rating is not permanent and may decline due to aging and wear caused by long-term use.

The protection rating does not apply to the propulsion system. After a flight in rain, it is recommended to keep it idling on the ground for 1 minute to prevent corrosion or rust to afflict the propulsion system (precipitation of more than 24.9 mm within 24 hours).
