You would see out the time you were contracted for!! The RAF is a way of life, not your personnel stepping stone to gain experience and your licenses. I would question your motives not your commitment. If you did join, and heaven forbid you were a good pilot, would you take FJ's or Helos?? I suspect you would do everything in your power not to shine. Enjoy Kidlington when you apply there, as I don't think, with the attitude you have, you will get very far at OASC.
