Question about Hitec Htcdr300

Actually, it is forbidden. Unless the airline has nothing against it.
Or you can remove the battery and take it with you in your hand luggage.

This scooter I can not recommend I have him only a few months and the charging cable is broken and he whistles when braking since the beginning I am very disappointed now I have to buy a new charging cable🤬 I would not take the case because it can be that he breaks down and then you have a broken scooter abroad
