> There was a web page someone mentioned a while ago with little
"helicopters" which used what looked like 4 or 5 pager motors. I don't

the motors and the frame which held the motors together.

know) but when I first saw the bots that's the ide aI had too! Never tried
it though cause at that point SB didn't have those little fans.
