One thing to note is that the G5 is the GFC500 controller. Sure it has a control panel but all the brains. AHRS, Air Data, etc are all the G5. If you want a GFC500 with the G500Txi you'll still have to install at least one G5. I suspect if there were Aspen integration that it would be the same. The GFC600 is more of the STEC stand-alone autopilot competitor.

The stec uses external data as well from an efis or air data computer. Not sure I see the difference. I’ve seen the 600 servos in person. Although I think they have different sizes per application the one I looked at could probably steer a bus....it was massive.

The difference is you always have a G5(in the certified version, I believe Experimentals can use the G3x Touch as the autopilot computer) so Marauder wanting integration without having to install a G5 isn't going to happen on the GFC500. For the GFC500 the 'autopilot computer' that talks to the servos is the G5.

But the G5 also does double duty as a backup which I assume you would want anyway.

I've got a BK KFC 150 autopilot in my 252 right now. It works and there isn't any reason to replace it. But it's inevitable that I will need to replace it at some point. This 3100 is looking like the best candidate. I have a G5, but it's just a back up and I won't install anything that doesn't fully integrate with my Aspen. 

It look like this 3100 would integrate even better than the current KFC150 which doesn't use the Aspen for vertical speed.
