Very cool engine

The most impressive small engine I've ever seen run was a small turbojet
in a
RC model.
It turned something over 100,000 rpm and the harmonics were amazing!
sounded like something between a wailing banshee and the warning horn for
the
end of time.
Do they still use any pulse jets in models? I was around 6 years old, which
would have been 1954, when I saw a control-line speed event with pulse jets.
I can still remember the pain in my ears and the vibration like it was
yesterday. My God, those things are loud.

I remember one of those from when I was a child (middle of last century).
They were *loud*.
I haven't seen one since.
There are a few Jetex sites up even today.
That's a slow burning solid fuel rocket engine.
I've thought about playing with those.
There are cheap enough - if you can get them.
But the jet was just plain eerie...
