I recently bought a quadcopter/drone Whirlwind XK X251 from Amazon UK, it was stopped by customs in qatar and Aramex emailed me to get a letter from Qatar Radio Control Sports Center. The guys in RC sports center were very helpful and suggested me to go to Aviation Safety office in Corniche as they were waiting for a new Drone Law before issuing any letters. They also told me that I also have to get a letter from MOI if it had a camera which it didn't. I went to Aviation Safety office and met the Director who is a very nice guy who told me they are drafting a new law regarding drones import and usage which will be out in a few weeks. I explained that the drone is really small (toy grade) with no camera and will be flown inside the compound activity center by my 6 year old son. I showed him the photos and he kindly agreed to issues a release letter which I picked up after a few days. I hope people find this useful and please look out for the new law if you are planning to import one.
