Flyer 1950
I can't, unfortunately, help you with a trip in the yeovilton sim, but thought that it might be worth a mention to let you know that the RAF now operate one of the most advanced helo-sims in the world, and it's the Seaking sim at RAF St Mawgan. I can't get you a trip in that either, but it is an avenue that you may wish to explore.
Best of luck
