Hello folks! today i discovered something: a video where one guy showed how to make any powered up/powerfunctions/rc motor a 9v motor! he used the pickups normally used in slotcars (he used carrera 124 pickups, i used the carrera digital 132 ones and they work too) and i had to try it myself. needless to say it works very well. you dont really need the copper tape neither do you need to solder, just wedging the cables in works too. i cant say anything about switches as i dont have 9v switches currently (will probably make ones with conductive tape) but i tried and it looks like it should work. the distance of the pickups is longer than the switch distance. the guy in the video also tried switches and it worked. here is the video:   and here is a link to the playlist with more of the same stuff: maybe this helps anyone wishing to jump into 9v.
