Hi there,
While building a small rc car using a RIM 55982 (18 x 14) I needed a way to lock the wheels to be able to drive it with a motor. Almost started drilling holes ..... and then, after removing the tire, it turned out there is a little notch inside the wheel.
Looks like it is a space for a tiny piece of plastic to slide in, to lock the axle to the wheel. Exactly what I'm looking for!
Have I missed something? Is there a LEGO part that fits this notch and locks the wheel? Or should I make it myself.
