If any of you are familiar with German model rocketry regulations, I would appreciate some help. I will be in Germany with my family for several weeks visiting in-laws. My wife wants me to "entertain" my nephews with some rocketry (building and launching), but I don't have any idea what is permitted.
What engines are legal? Where (typically) can I buy them? Where can they be launched? Does one require any kind of permit/permission?
Thanks in advance. Oh, and if there are any clubs in the area (Heidenheim,
30 km north of Ulm), that would be interesting to hear of.
