The price of $53,400 I'm sure is for a complete A/P system, you only actually need the DFC2100 computer the servos are all the same, plus they are already installed in your SE...The installation of the computer would be minimal....from what I understand and the inquires I have made with S-TEC over the last few years...Robert

Do you have confirmation on the question whether it will take the altitude preselect, the vertical speed (in vertical speed mode), the IAS (in IAS hold mode, the barometric setting, etc, etc from the Garmin G500?

Here the Answer from Genesys
· The documentation you sent says "The Cessna 182 and Cessna 210 will only be offered as 2-Axis systems". This seems to suggest that we would lose the yaw damper, if we already have one on our STEC 55X.“
There were no Yaw Damper STC’s available for the 182 and 210 models for the 55X and are not included in the 3100 STC list.
If we already have a yaw damper STC on our current AP’s we will most likely offer it as an option to the 3100.
Bear in mind – we do not integrate to 3rd party Yaw Dampers that may be on the aircraft.
· Do you have confirmation on the question whether it will take the altitude preselect, the vertical speed (in vertical speed mode), the IAS (in IAS hold mode, the barometric setting, etc, etc from the Garmin G500?
The G500/600 interface will allow the 3100 to read ALT and VS bugs from the G500/600 EFIS display. If you set these bugs on the 3100 bezel then they will be updated on the G500/600 display.
The G500/600 doesn’t offer an IAS bug so that mode will be controlled through the 3100 Bezel and the IAS targets set by using the UP/DN buttons.
· When you purchase a complete S-Tec 3100 kit with servos, are the new servos A/C electric instead of the D/C type that we currently have
The servos are the same DC servos we use for our current AP’s as they provide better performance. DC motors develop constant torque over a wide speed application making it a better choice than an AC motor. Retaining the current servos allows for an economical upgrade path if an existing S-TEC AP is installed.

What I would really like to know before committing to what looks to be a very positive upgrade is this: will the STEC 3100 do a better job of flying our aircraft precisely (eg intercepts, heading turns, glideslope capture....) than the 55X (which tends to hunt before it captures) - or will it be a similar performance albeit with the additional feautures (like envelope protection and airspeed hold)? All the sales pitch is around features rather than performance. Can Genesys give us a steer (pun intended) on this? If so, my order will be in the post.

Would you have a direct link to the Beechtalk discussions?
The STEC 3100 has been installed on the Silver Eagle I manage. Pilot reports are not completely encouraging. The AP flies straight & level and enroute turns correctly in smooth air, but often as little as a single smallish turbulence will destabilise it and it makes the plane enter an AP-induced dutch roll. It behaves less bad without yaw damper, but will still on occasion enter roll oscillations that the autopilot seems to induce. If one fights the autopilot and restabilise the plane by hand, it will usually stay put for a while.
The autopilot rather often has a failure (auto-disconnects) when flying low. Less so when established in higher level cruise.
ILS intercept performance is poor (at 150-160 kts, a speed taken to integrate with the heavy iron traffic). It overshoots the localiser (by more than half deviation), turns back, overshoots again. Up to now, we didn't have a pilot leave it a third chance, at that point we turn the AP off and fly the approach by hand.
GNSS-based RNAV approaches work better.
We are waiting for special software from Genesys to connect a computer to the autopilot and record debugging data in real time.

Thanks for the update. That is really helpful to know.
I read this on beechtalk.com
I’ve had the STEC 3100 for a few months now. It started out bad, really bad. Porpoising constantly and unable to hold a track. Apparently the software was wrong, it was delivered with software for a 28v system and I have a 14v system. Software update fixed the porpoising issue, but the I started getting constant autopilot failures.
The autopilot failures became so frequent that the autopilot was unusable. One time it shut off as I was in a climbing turn on a SID in solid IMC. I was not amused.
It spent another 2.5 months at the shop getting issues sorted out, and now it seems to be working well. I flew it about 15 hours over the weekend with no real issues and it held track and altitude rock solid. I’m still reluctant to trust it in IMC, but if it continues to perform well, I’ll try it on a couple of approaches.
