Re: small RC hovering models...I saw an amazing example of same at a
conference last fall...fellow had purchased it in Japan...consisted of 4
small PM/DC motors (the type you see in cheap toys) mounted on a
styrofoam ring about 12" in dia.... each motor had a plastic prop about
4' in dia....control electronics and batteries (about 8 oz. worth) in
the center...stability was accomplished via a small *GYROSCOPE* (no
kidding!) in the center pod...gyro had small, dual-gimbeled flywheel
with some sort of proportional sensor feedback (don't recall the
method)...gyro parts (except the flywheel and bearings) were
injection-molded plastic....owner said the whole thing cost about $400
US....I might be able to track him down if anyone's desperately
interested....reply by email
