I winter in the Bahamas. Bringing in a phantom is a 'crap shoot'. Brought one in twice and no problem. Last time $450 usd in duties.
They look for revenue. Don't be last in line as they rummage thru your luggage. It depends on the customs agent when arriving. Nassau airport is the worst. They even charged duty on the camera. add insult to injury they charged sales tax of 7%.
paradise is not cheap!! no issues about use, just don't charge anyone for your service unless you want to be deported!
