Sounds like yoke inductance to me. One of the two big differences between the
G-80 and the WG that allows for faster speeds on the G-80 is fewer yoke winds,
hence less inductance. The other was higher supply voltages which allows faster
charging of the yoke inductance. Of course, lower inductance + high voltages =
higher currents = higher fire hazard.
