Hey paolotheflyer,
Have some bad news regarding aerobatics. The long and short answer is there is absolutely nothing. In fact, there was a group about a year ago that looked into simply starting an aerobatic club, and that wasn't even feasible. The GCAA is very very anti aerobatic it would seem and in fact, i think they might even consider it to be military type flying. I looked into bringing over an aerobatic airplane myself and it is completely cost prohibitive (unless your a heck of lot more wealthy than most pilots I know). For example, a sectional chart runs about 525 dirhams (nearly $150). As for renting regular airplanes, there really isn't much there either. There are some microlights you can fly in Ras Al Khaimah, but that is about it. Sorry to break the bad news to you, its been killing me for the past 3 years not being able to bug smash
. Good luck with your move over here.
