Hi, I realized some airlines like SQ and Emirates dont allow to hand carry drones. So is it safe to check-in P4P in its own original box? Im pallning to put it in my checked in trolley luggae so it wont be an eye candy to some airline staff.

Most airlines don't want the LiPo batteries as checked luggage. If you at least bring the batteries on as carry on while everything else is checked, then you could be ok. I'd recommend checking with the airline you're using to see what their policies are.

Make sure your batteries are drained ,

I would contact them and ask them, Lipo batteries in the hold undergoing decompression and large temperature changes do catch fire, which is why the airlines object. Contact them by email and get an express yes or no and take the confirmation with you when you fly to be sure.
