POBJOY,
Turbulent - lucky you. I've always wanted to fly one, ever since I saw one at a Tiger Club display at Ramsgate in the 50s, but alas, I think I'm too big and heavy for that now. However, I know about "pitstops". I once did a 200nm ferry in a MotorFalke!
Excuse my ignorance, but what's a B-Tow?
**Sywell - the first stop in my qualifying XC. WW-Sywell-Kidlington-WW, non-radio if you can believe it!
