Not strange at all. The g-2700sdx and g-2800sdx used the same connectors
with 6 pins and used the 6th pin for the automatic slowdown when you got
close to a stop. You can actually interchange the g-1000sdx, g-2700sdx, and
g-2800sdx control boxes and they work just fine, the only thing is that if
you have a g-2700 or g-2800 rotor with a g-1000sdx box you won't get the
automatic slowdown feature. I haven't tried it but I believe the g-800sdx
box is the same as the g-1000sdx and could probably drive the other rotors
just as well.
