all this stuff has been answered before in great detail. I suggest you PM Heliport the moderator - he'll put you straight ! Failing that, do a search. I have spoken to Ocean before. They are exceptionally helpful ( like no other outfit I have ever come across ) and they get great reports on here. Easy - this is a word which does not go hand in hand with the heli-game. It is all vast amounts of cash and shere grit and determination to get anywhere. Then you have to be very lucky !!
