Planetary wheel, or at least using what I did before with a direct output.
I still don't know if this is a planetary gear but it does do a reduction and is encased within the wheel. Unfortunately the 8448 wheels do not have holes in the right places to do this. (note: this works with the tire put in place)
Once again, the blue axel is the input and the red gear MUST not be attached to the hub.
