Hoping to fly to Italy this weekend taking my P4 Pro as cabin baggage. According to the Ryanair website you can take a drone in cabin baggage as long as batteries are under a certain power (which the P4 ones are).

However anyone got any practical experience of doing this?

I don't really see how the airline will know anything about this as it will be airport security who check my cabin baggage.

Recently flew to South Africa with Emirates. No problems with security in the UK, Dubai or South Africa with the batteries.
