Hi Norman,
Thanks for the detailed response.
I would be happy to come over to Altona for any help you might be able to give (don’t think I have access to PM you but if you PM me with your contact number will give you a call and we can discuss details).
I think the “choking” that you mentioned is part of it. When I was launching the kite it didn’t just move the side of the window and then easily move up to the autozenith point. Noted that when I pulled the bar in once overhead it seemed to move backward a foot or so which I was not expecting.
So could be my understanding which might be out.
Look forward to catching up and sorting out
Thanks, Shane
