@Exult Maybe this answers your questions:
1. where does one buy iFlites in Europe?
I think there used to be a possibility to buy in UK. But I would order directly from Patrick Tan. The shipping costs are amazingly low (Singapore - Germany 9 USD) and the shipping takes hardly 1 week.
2. during a session, what does one aim for?
I always fly gliders when
a) there is no wind
b) I am traveling with small luggage (backpack or less)
c) so small and compact - is my "always with me kite"
d) sometimes in between when I don't have the time/opportunity to get out to fly (from 1-, 2- or 4-lines)
the goal is
e) switch off and relax / have fun
f) to find the breeze or the thermal that keeps the glider up
g) depending on the glider (I have 9 different gliders), location and wind conditions I fly what fits (figures, training, ...)
To fly gliders you don't have to have an "expensive" Horvath from Switzerland. For a very small budget there is the Piuma from Italy, the iFlite is not expensive either. And if you can build it yourself, there are many open source plans. With this I want to say that you can start even with a small budget :-)
You don't necessarily have to fly indoors with a glider (although that's a lot of fun!). I fly outside most of the time. Whenever conditions, time or wind don't allow anything else (2- or 4-line).
