right, voice coils 'the right choice, but there's some other interesting
parts coming into life: digital servos for high-speed
controlling of model helicopters: i have one on my table wich is able
to push 250 grams up to 50 times per second exactly reproducible with a
resolution
of 10 Bits into 1024 positions over an angle of 60 degrees:
High-Speed digital Servos at a cost of about 100$ per piece.
