Suggest you contact Joe Mcbride, Dave Presta et al for info.
Just be careful that you stengthen the aircraft appropriately, to avoid [link=http://media.putfile.com/Yellow-F-18-]this[/link]
SeaLance,
Gordon's info is a little out of date. That kit has been completely redesigned by Yellow. It's internals are completely different than what came in the kit in his link. You can build the new kit for turbine power without any mods or deviations from the plans/instructions. Gordon is correct, though, that Joe McBride is a good person to talk to regarding this airplane. He's the unofficial test-pilot for everyone's F-18.
