In this Santa Fe I built in, a RC module from the RC Race Buggy 8475. To fit the module in the train I had to resolder the powerprint from the baseprint with a flatcable. Also the switches I placed on the other side of the print. As antenna I used a wire of 15cm, this works fine over a distance of 15 meters.
The train rides forward and backwards in 3 power-steps. The headlight is connected to the auxiliary output.
The left and right steerings drives 2 micromoters wich pushes the previous wagon away. See on the brickshelf-folder for the litlle movies.
