I really like that - would prefer it in 1/10 though

I remember reading about the engine as a standalone piece. Quite a fascinating device, really - I would be interested to see one in an on-road application, although having it in this form is already quite neat!

Locked rear diff and open front (according to the webpage)... strange combination!
