Hello -- Karsten & Jens
Thanks for all of the help you are giving me -- it is much appreciated. Sadly I haven't made much progress as yet on my own kite as I am short on time, but will keep you posted as things progress. I have been studying the plan for the 180/2 on Rainer Kregovski's Web-site and may ask for some help in translating a couple of the terms used (to confirm that my understanding is correct).
I also now understand about the "curve connector" that you mention in your post -- I didn't realise that the Gierl-Roloplan is bowed under tension rather than using a fixed angled connector (150 deg).
Karsten -- your kite looks fabulous! When you have a spare moment, please a post a full photo of it so I can see it in its full glory! I have a long way to go before I am able to produce such a flying machine.
...in the meanwhile take care.
Best wishes form the UK
Simon
