The wheels on the bus

This Hungarian Credo Econell 12 bus was built by Gabor Horvath in 1:24 scale, and judging from the source photos, it's a very accurate replica of the real vehicle. Making it even more interesting, the whole bus is remote-controlled and can be driven and steered (the doors can also be opened/closed remotely). 

Take a look at the video below to see all the functions in action, then head over to MOCPages for more images, including shots of all the Technic mechanisms that make the bus work. The amount of Technic work crammed into this frame is incredible.
