- The 1: 1 plans to anchor the brackets to the rods are a very good idea. To save page space but brackets are printed even reduced, which then allows only an approximate position and subsequently causes problems.
- The details of the hose lengths are simply wrong - instead it must mm cm hot.
- Some of the tracks are strong left- or right-wing in terms of curves. According to one of the two tubes of a track must be longer than the other - this is found in the manual not be considered.
- The always like assembly of 78 basic parts is to say the least a bit tiresome in its monotony.
- Even if the material quality for the price is ok, parts break times in the correction. This can not be readily replaced in advanced construction then, without again disassemble the rods and thus large parts of the plant. Here help you either with tape (see below) or tried to improvise from existing fortunately remaining parts of something.
- The manufacturing tolerance is tolerable, but could be better. Sometimes the "to clip" of the tubes is really painful hard, resulting in difficult to reach places to frustration.
- "Everything depends on everything". If you installed a section and successfully tested / has assembled to build the next success - to determine afterwards that has moved in the first section again somewhat. This goes to three lanes still bearable, but when all 5 sections are mounted is it really, really tricky - especially if you have not worked exactly under construction 100%. I spent about 4 hours with the final adjustment.
- The final adjustment is thus difficult that now a lot of material is installed and one can not access is good everywhere. Balls - especially at 5-fold loop - also fall on the base plate and are due to the many parts there too difficult to reach. This makes the Try & Error a real ordeal.
- Especially the 5-Looping is tricky, the manual unhelpful. In order to achieve the correct shape of the arches here also helps physical knowledge.
- A little more creative courage is generally helpful - I have some, especially critical elements with Isoliertape additionally stabilized.
Then, when after several hours (with me 25) finally Everything comes back that is of course great, but you also know what a rocky road it has behind it. Probably a good learning effect available: a second building "from scratch" would probably result in a less distorted, immediately better running web. Here, of course, is the best strategy, only to start with one of the easier tracks and then work your way up the levels - the 5 Series has already pretty in itself.
In sum, of course, still a great pastime, very "physical", clever, as a result, impressive. But you have to like such things.
