TruTrak Model Choice?
 

OK,
So I've settled on TruTrak as the AP for my RV-10. However I'm not sure on which model -- RV-10 AP or the DigiFlightIISGV. According to the product info webpage, the only difference in the 2 is the RV-10 AP has altitude select where the Digiflight does not. However, the RV-10 AP also lists for $2000 more. Is there any compelling reason to pay the extra $2K for the RV-10 AP? Would a suitable compromise be to order the RV-10 AP servo's/install kit and the DigiFlight control head?

Thanks,
Todd

Form factor is also an issue - RV-10 AP is offered as a horizontal head unit only, while the Digiflight II can be had as a 2.25" round or a horizontal unit.

Not exactly
 

the Digiflight comes either way:

the Digiflight comes either way as doug said
(I got ahead of myself )

Non-issue for me
 

Yep, didn't list form factor as a difference, but the horizontal version is what I'm planning on so it's a non-issue for me. Are there any other considerations that I might want to take into account?

Are you planning on an EFIS and if so, what model? The AFS EFIS can control a VSGV to effectively provide altitude select and other features (e.g. ILS approaches from an SL-30 or other nav radio).

Mike has it right, you need to consider the rest of the instrumentation in the panel.

I went with the Digiflight II VSGV, after talking to Grand Rapids Technology, as I already had their EFIS units in the plane. GRT says they worked with TruTrack to ensure the compatibility of the two.

Also, I checked with TruTrack, got the exact same response----

Call them, good folks.

Guys, thanks for the input. Although I have yet to select an EFIS, the 3 brands I'm looking at all work well with the TruTrak line. Sounds like the DigiFlight II is the way to go for my situation.

GPS Steering
 

Todd, one thing to be aware of is that in order to use the GPS Steering feature (no overshoots of the waypoints) you have to have an output from the GPS that delivers the right signal - most IFR certified GPS units provide this as does the GRT EFIS with ARINC.

Another important consideration, Todd
 

...is that the Digiflight II VSVG will fly a coupled ILS approach from a 430W/SL30 if you want. From what I understand, the others won't.
