Time to rip the wheel from your R/C car. If it comes with a gear in it as mine did, then you might want to keep it in to act as a spacer/ washer for your wheel.

I used a little superglue again to mount my wheel, the same way as I did the encoder. You may have a different diameter hole in your wheel to your rod, so I reccommend you roll up some paper to pad out the hole, or gum it up with some Blu-tac. I don't have any pictures of ripping the wheel out, partly because they're all different and partly because mine was found at the bottom of my parts bin.

Now all you need to do is stick the board to the bottom of the project box (pressure sensitive tape again) and drill a hole in the side of the case for the cable to escape from. Then clip/screw the two halves of the box together and test it!
