... Can produce a fairly respectable model. Unfortunately, the orbit of Venus disc has with me in spite of all care and diligence warped tidy. Unfortunately, I had reasons of rigidity used in this case Ponal Express, because you can make in hindsight nothing more. I can really recommend to observe the cardboard running directions exactly and to use as soon as possible after gluing the large portions large boards or the like to complain. It really places a miserable fumbling, especially with the smaller components of the kit. Fingers Man beschmirt with tons of adhesive, it is almost impossible to really stick all spills free and clean. Nevertheless, does the thing; with the Venuseierei I can live well, and the model is really what forth. Maintaining the Erdachsneigung and the rotation of the earth are cleverly solved. One should not forget that it is here managed to simulate the movements of four celestial bodies with a single crank. Who wants it more exactly, can indeed fit a pair of electric motors on plywood panels and control accurate to the second round on a microcontroller. But the mechanism has simply a certain nostalgic charm, which was certainly intended by the developers. Took a lot of time and nerves, but also fun. The next project will probably come.
