Good tip on the weight, It actually rang a bell with me, so I re-read the Fury instruction book and indeed there is a section which says "Use weights on the ends of the bottom cross spars to aid centrifugal rotation (back spins, 540's, lazy susan's axels). It also warns about compromising low wind performance.
On the day in question there was barely any wind, so I was forced to use the SUL just to get in the air. And even then it wasn't consistent.
I can also see the sense in flying the nose slightly down to help the setup.
All tips are welcome and your experience is valuable to me, so thank you all.
I think then that I am still better off getting the half axel technique right on the Gemini's first and then transferring that experience to the fury's. Maybe using some added weights to either kite if the conditions allow.
I'm sure I've seen brass collets that might do the trick. (no pun intended)
cheers,
Paul.
