I think you'll find that not only does it quench better but may fire
at a higher voltage as well. I've been testing my new rotary in
several different modes at very low power and moderately high voltage
levels. I could get 4 series gaps to fire with the wheel static and
about 10kV but with the wheel spinning and air rushing round, I could
only get two to conduct.
