One thing I am concerned about with a 5th line on a waroo, is that once the kite inverts (release on the 5th line), how does it behave when you power it back up? There's a good posibility the rear lines will tangle on the trailing edge of the wing tips.

Fortunately you could just release to the 5th line again.

Maybe I'll try this out and give you guys a report. I 'll just hook up my 5 line C kite bar as a quick test.
