It's the propeller and tail fins that are amusing, plus the wings, of course. Funny to put wings on the top. This car would have made a fabulous helicopter. The creator just couldn't get it together for that. And, of course, it would have been more of a problem driven it if it had blades on top.
I think when I was trying what I've assumed for years is a bad socket and
the three blades started to turn (oops) with the chains thrown over one of
two of them to hold the assembly in place while I was removing and replacing
the blades, I think it scared the electrics into surrendering and going back to
working.
