Yes, I for one would be interested in the exact wind range, and if he has any special considerations or precautions before launching.
I have asked him...
"The wind area for the big kites as well as for the long train lies
with from approx. 3 to 4 Bft. Under it the steering pressure is absent and it is difficult to get the kite around an corner.
About that the power can become high in such a way that one cannot hold them alone. Then it needs a second one, a co-pilot. Otherwise the risk becomes for the kite , the pilot and above all perhaps to spectators too largely.
I do not take special safety measures or preparations before.
The weather should feel well very continuously, the wind not bumpy and the airfield freely from obstacles and above all from passers-by.
So I have built up my teams as well as the big dragons to 7.6 metres of span already alone and also have flown without assistants.
However, there I was years younger a few more, round about 75. As yet, however, I am confident to fly safely these kites , indeed, not more without assistants, for safety reasons.For the 9 Meter as well as of 12 Meter (wingspann) now i need an assistant.
And the train (16 Stack) do not get I any more together. Of it I myself have only two or three team kites.
So Dirk, this are first of all the answers which you can give to the friends in GWTW Forum associated with with greetings from me."
