Impressive! However, I can go further than this in both ambition and stupidity -
on yet another one of those strokes of "genius" that seem to inspire us as kids, I
plugged the motor into the mains with one of those leads that go into cassette
recorders. The lead was a perfect match for the end of the 4.5V lead, so it seemed
obvious. The worse of it all was that I was aware of the difference between AC and
DC current, but thought it would be worth having a go anyway. So I ran this motor
for an *incredibly* short period of time at 240V. It literally blew up, and I
still have a charred bit of it on my desk at work...

I like it when this happens - it means that your bracing is working properly :-)

That's the one - I assume the car on your web page is the 8860? I received this as
a present one Christmas along with the 4.5V motor set. However, neither my parents
nor I had realised that you also needed the 4.5V motor gear reduction box to
motorise it if you followed the instructions. Undeterred, I attached some more
gear reduction hanging off the back of the engine as I didn't want to remove the
cylinders in the way the official version asked you to. The result? A painfully
slow 8860. It was still great at the time though :-)
