Charlie Zulu.......Many thanks for the Piper info. Will make note of it and put it to good use when I get my hands on the beast(s)!
The main difference I can see is the view (or lack of) of the ground.
Sitting on the wing instead of hanging from it blocks out most of your view. Still I suppose this is componsated by the better view in turns!
Thnks again
