if i were you i would do this : remove the propellers from the drone and store them in another location of your bag
Remove the battery and put it in a specific lipo battery bag if you have, otherwise just in another location
The craft without battery and wihout propellers looks a bit less like a drone for the average TSA staff
Maybe that would be enough to fool them
I just can't imagine DUBAI TSA confiscating a +1000 € drone from the hands of a passenger...but who knows
in worst situation, when they see the drone without propellers and battery and if they insist that it is indeed a forbidden drone, you can still pretend it is broken and you came in Dubai (or elsewhere) to have it repaired.
