Rocket assebly started
Today I started to assembly the Video Courier by Klima. Here is the freshly glued motor mount tube for the D7-3.

Launch Lug
I got interested in rocketry. Building and flying your own rocket models. Unfortunately, I live in Germany. This land has by far the most unfriendly conditions for rocketry. Even tougher luck is when you live, like me, in a city with an airport.
But despite all legal prohibitions for this hobby, you find some enthusiasts in Germany, which do fly model rockets. Often they go and fly them in Czech Republic or Switzerland, where the rectrictions are not so tough.
Generally, in Germany you may start a rocket only if it uses no more than 20 g of propellant mass. (The law does not say whether this is true also for water or air rockets.) Rocket engines have to be approved by BAM. They allow only engines up to D7.
No clustering or multi-stage is allowed. No engine import is allowed (except for approved Estes engines from an approved importer). And you may not fligh too high. You have to check how high you may fly with the respective local air traffic control authority. And you have to ask the land-owner whether you may start the rocket from his ground.
Of course there are ways how to fly higher and use more powerful, clustered or multi-stage engines. But you have to pass (and pay) an exam and you have to obey the strict storage rules for explosives. Moreover, you have to ask and pay the air traffic control for the permit to fly higher than usual.
Despite all these restrictions, I ordered a model rocket. Currently I am looking for a suitable place to start it and cheking with the air traffic control about the fly height.
