check out this guy's site for tiny helicopters.. he
builds them from scratch:

the little yellow one only weighs 1.7 ounces..

soon... Of coarse there are also a lot of free flight helicopters that are
out there too... A small model does not have to be controlled to be
stable... The R/C guys consider these too boring to fly...

10446 Sat, 19 Feb 2000 00:03:58 -0700 [alt-beam] BEAM: Tendency toward miniaturization beam@sgiblab.sgi.com Jean auBois Isn't it odd that people are building smaller and smaller devices that are
often more and more fragile? If there was ever a field that is moving
toward nanotechnology, this would be the one.

However, I find it sort of discouraging that the larger projects aren't
doing very well. Mr. Tilden reported that some people wanted to make his
Lampbot go faster so they upped the voltage, burning out a lot of stuff
(um... everything?) And he said that he wanted Roswell to walk in the
parade at Telluride but had horrid motor problems.

I don't think it is because we _can't_ control bigger things with BEAM
technology -- perhaps it is just easier to build smaller things that work
fairly well.



Just food for thought.
