The servos are not compatible with the G3X or G3X Touch. Totally different creatures.
The AOA pitot can be used with both although there does not appear to be any formal testing data out there that shows what if any performance impact using one with the other may have. The concept of how they work is basically the same so many have used them interchangeably.
Like Dan, I am preparing to upgrade a panel that has, in part, a Dynon AP74 and Dynon SV32 servos. Which EFIS/autopilot systems are compatible with the dynon servos? I think the Dynon and Advanced Flight Systems are. Can anyone verify that?
