Righty,
AMA doesn't cover the Bahamas.

BigK,
Welcome to RCU. It's a terrific place with a lot of great people.

You have the engine plane and radio equipment, that's the big stuff. As Righty mentioned you now need support stuff; like fuel, a fuel pump, extra fuel line (at least 1 metre), a glow plug ignitor and charger, a couple extra props (I'd suggest 11 X 5's), an extra glow plug, and while this isn't "necessary" it's a huge help; get a 12 volt starter and 12 volt battery with charger. You use them to spin over the engine, and they make life MUCH easier.

You said you've been out with friends, so I'm assuming that you have someone lined up to help you fly your plane.

Good luck, and have fun!
Dennis-
