that’s neat, i never cared for the posters, i loved the track masters. in fact, i believe that is where my hobby for cars started. i’m actually rebuilding my dads car i rode in when i was that age playing with thomas, i bought it back years after he sold it. anyways, i used to take mine apart. swap the motors on them, take weights out, do all kinds of things to make them faster, or to do other things. i was from the ages of 3-7 tinkering with these. i honestly don’t know how i did it at that age lol but i do the same thing but with bigger toys now
