This is still a bit of a mess. Having not tuned in to this issue for some time, I was becoming very confused about which version of G3X is available in which aircraft. Looking closely at the Sting now I can see the differences but it is not obvious unless you really know the detail, I now know how to identify the MSobo version by disengaging the AP using a mapped button; in the WT e.g. in the Sting, the AP symbol in the AFCS strip flashes yellow 5 times and then disappears which is correct. However in the Asobo version, disengaging with a mapped button causes the AP sysmbol to change to RED and remains flashing until the AP button on the AP controller in the aircraft is operated with the mouse !
