Judging by the schematic in the new G-800SA manual, they totally changed
it, and reduced the part count by about 2/3, which has to be a step forward
in reliability. It works differently now -- for example, the indicator no
longer drives around to full counter-clockwise when the rotor cable is
disconnected. Instead, the overlap light comes on, regardless of the
actual position of the indicator.
The only bad things I can see is that they are now using one of those
darned Molex jacks on the back of the controller instead of something
sturdier, and that the non-preset controllers use a locking motor
switch. It's awfully easy to press too hard, and have the antenna drive
around against the stop with the motor still running. I've done this a
number of times, though, so the motor must be fairly able to handle the
resulting load.
