I want to take my small (<250 grams) drone on a plane in Europe? Are there any rules regarding this? Should the drone go in carry-on luggage or in the hold?
I am not a legal expert by any means, so I just want to say that disclaimer.
As far as I am aware, you can check in the drone itself, but due to their volatile nature, most airlines will require you to carry LiPos in your carry-on luggage so you can react quickly in case the worst happens.
As always, check with your specific airline and the laws specific to your country of origin and your destination.
