I love X-plane, haha.
I try these landings quite often, and am rarely successful. The only method which gives me a sort of consistent landing is to do what is done in the movie of the C-130. I come in full-flaps, at the lowest speed I can without stalling, along the long axis of the deck, and go full thrust reverse just before I touch down.
