PLMKWYT,

Pretty neat.

I have a friend who built something very similar to that about 2 years ago. He
was playing around with gear trains (gearing up and gearing down) and he got a
geared-motor to drive a gear train that spun up a model just like yours enough
that it would lift-off on its own.

Yeah, I figured someone else had to think of something like this sometime. I
know how to make a gear train that can get it spinning fast enough, but I
haven't quite figured out how to make it release well yet.

(...) Try coupling it to the gear train using a worm gear as the coupling. Due to the loose fit, it will eventually lift off. Tom (21 years ago, 4-Jun-03, to lugnet.build)
