Yep, Baz'll help sort out gyros - there aren't many better than him.
But you'll still make life much easier on yourself if you can learn the principals, at least, before you go to Bristol. FFF's tip for the day: buy a globe for about £5 from WHSmith, and find an appropriate object to use as a "gyro" - a beer mat or something. Then, position the beer m.. sorry, gyro, over the globe. Turn the globe, and move the gyro with it, ensuring the gyro continues to point at the same place relative to the corner of the living room ceiling. Et voila - drift. You can do the same for wander - move the gyro around the globe without moving the globe, but keep the gyro pointing the same way. Really helped me understand it...
Good luck!
