If you're worried get a drone that can be disassembled, so that it doesn't look like a drone on X-ray.
But most probably you can just pass it as it is. We got a big one through without problem. And I think Virgin have small drones but probably a bit expensive.
Virgin is 1.5x more expensive than other Lebanese drone shops :)
