After adding decoders to a ready to run Faller Car System Car the next challenge is to completely build a car yourself. The truck or car to fit your landscape is probably not in the Faller catalog anyway.
To do this you will need a steering mechanism, a motor and gears. I have tested some gears and want to share my opinion with you.

Faller Setra

First in line is a standard Faller car. This is a motor and worm gear from the Faller Setra bus. This is the luxury set which includes head and tail lights and has beautiful white (according to the picture) interior lights. About the lights I will write later.

The worm gear in this bus is an improvement. Older buses I have seen have a very delicate construction which tend to break after a few hours. This construction is much better.
The motor sounds like we are used to, it behaves reasonable. The bus runs at a blazing speed!

In the picture you will not see any cables, they are all removed in preparation of the dinamo MCC decoder.
