Salut!
Reading French is fine for me. I had it in school nearly 3 years, but i have to apologize, that i do write in English. I would be too embaressed to write in French. But i like to answer your questions.
First of all, most rides do not have any motor in (except my Fabbribooster and Turbo Force). I saw that my Faller rides rarely move. So i decided to leave them out to make them more detailed. They are no kits and i do not offer any. It is just a hobby for me. I make model rides for nearly 20 years now, most of them destroyed and back in other rides. I am a kitbasher. So i take parts from other rides and make some new. The trailers i use are mainly from Herpa. All the other parts come, as you noticed correctly, from Faller. I am sorry that i do not have any pictures from setting up the rides. I use the colours and glue from Revell.
I travel alot on german and dutch fairs to take fotos for for the decal sets. Most of them are not stored, due to an crash on my pc. (Which is the same problem with the setting up pics)
At the moment i am working on the model of 30 meter version of Fabbribooster. The second ride is the new "Fun Factory" by KMG.
