Unfortunately, I have found little information until now, if drones are allowed to fly in Bahrain. Although, I have found the import regulations of the Kingdom on the customs side. There are model aircrafts listed as prohibited items. From this I conclude that the import of multicopters is not allowed in Bahrain.
We have researched the listed drone regulations for Bahrain to the best of our knowledge. We cannot guarantee the correctness of the information. If you want to be on the safe side, contact the competent aviation authority. Alternatively, you can also ask the embassy in your country for further information about the regulations. Please leave us a comment when you receive news and/or gain experience with your copter in Bahrain!
