Hello,

I would like to fly my Spark near and around my boat, but i am afraid the metal structure can cause issues with its magnetic sensors. Does enybody know if this is known to be an issue or if it's going to be fine. The boat is made of steel.

Kind regards,
Tim

You need to try that.
Dont start from the boats steel surface, put a meter or so between steel/metal and the spark.
Land in hand, perhaps start in hand, too

Hello and good day Tim. Thank you for the inquiry. Just a reminder that when flying on a moving boat, especially landing, you need to pay attention to the relative speed between the drone and the boat. We suggest that you land the drone by controlling the RC because if the boat moved, the home point will not be the same. Besides, you should also notice about the flight height and do not fly too near to the boat.
Be careful and enjoy your flight. Thank you.
