I can't imagine you'll have much of a problem - your rear barrier will be the number of batteries you can carry. It varies from airline to airline - most have guidelines on what you can carry on battery wise.
Aer Lingus for example...
https://www.aerlingus.com/Services/Guid ... _Goods.pdf
" Lithium ion batteries, with a Watt-hour rating exceeding 100Wh but not
exceeding 160Wh for consumer electronic devices. No more than two spare
batteries may be carried in carry-on baggage only. These batteries must be
individually protected to prevent short circuits. Equipment containing such
batteries may be in checked or carry-on baggage. "
They appear to only allow TWO spare batteries. I assume that's one in the device itself, and two spares. I have four, so I'd simply have to give the other battery to anyone else travelling with me as carry on. Then of course there's two FVP monitor batteries, rc controller batteries, and I usually have a dslr or something with me two, 3 or 4 batteries with it. Probably a mixture of battery types totalling ten or more. Nightmare!
I flew from Belfast to Bristol a few months ago with phantom, 2 batteries as carry on, Belfast international airport must not have seen many quadrotors before, everything was taken out of the case, swabbed, x-rayed TWICE. I know they have to be careful, but **** it's such a pain in the backside.
Coming back through Bristol, they didn't even open the case! I heard the x-ray operator talking to someone else and they knew what it was.
Just checked British Airways limits - much the same as Aer Lingus - just to give you an idea of what is allowed.
