I am building an RV-6 that I am setting up for IFR. I have a Trio EZ Pilot with a Navaid Servo. After more research, I have learned that Alt Hold is highly desired for IFR in the 6, so I am looking at options to add one. I found an affordable Trio Alt Hold, but will need to buy another servo. Cost will be 800-900 (will be used).
I have a Dynon D-100 and was thinking of adding a Dynon Servo and Using the Dynon AP for Alt Hold. I have the HS-34, so I have a knob for easily setting the alt. I can also easily engage the AP via the Disconnect switch. The potential down side is that I have two different autopilots with two disconnect switches. I am also afraid it could impact resale value. This option would be about $700. I suppose I could add a combined disconnect switch also, allowing to disconnect either or both.
Third option is to sell the Trio setup and buy two Dynon servos. The upside is that I can use the ARINC interface from the KLN-90B that I have. I am told the RS-232 output is slow and the Trio will not be solid when connected to this. The downside here is that I lose my Turn Coordinator on the Trio. This is part of my backup strategy if the D-100 fails. It would be my only Attitude backup. I do have the Garmin 396 and it has a turn coordinator display, but I am unsure if this is a reliable as the Trio. Net of selling the Trio, this option should be about $700-800.
I am hoping the community can help me a bit here. I do not have my IFR ticket yet and this is my first build.
Thanks in advance.
