Could someone please suggest to me how they would equip the ideal IFR Garmin panel? I printed off their product sheets but there are so many options that Im confused. Thanks
I agree, how necessary is dual AHARS?

I have a functionally similar panel in m 7A (except no remote devices and dual G3X Touch displays). That is exactly how I would build an 8.
It is at a minimum very convenient (and safer) to have two comm radios. I always need to get weather or listen in to Tower/CTAF before being dumped into busy airspace under IFR. Requesting to leave current ATC frequency to do these things is not realistic to me. I have two and really wouldn't consider going with just one.
It's also a great idea to keep 121.5 tuned the second radio while enroute for those days when you miss a call on frequency or you don't get the call before you run out of coverage on the current frequency. They'll find you on 121.5.
With dual GSU AHRS and the G5 (built-in AHRS) you end up with at least 3 attitude sources in this setup.
Walt will have to chime in on the AHRS count as there may also be a "back up" AHRS in the GTX that can be used on a Garmin portable or an Ipad as a 4th attitude source if really needed.

Walt... what's the price tag on that panel you showed above?
Doesn't the GTN 650 or 750 give you that additional comm? Confused.
I was considering the GTN 650 as the only radio. Do I really need another?

(figure about 30K for equip give or take)
Yes the 650/750 has full com, if you want dual com you need another radio like the remote mounted GTR20 or panel mount GTR200.
Nope dont really "need" it, but for a little extra (about 1k) you can have the remote mounted com 2 which comes in handy and makes a great back-up.
Well, about $1K for the second radio, but then you also need an audio panel, and it all starts to take up a lot of space on an RV-8 panel. The remote helps that some, although the instrument bay gets pretty full of boxes too.
But my real point was that radios have gotten to be so reliable that I'm not convinced I really need a backup. I lost coms once in a rented 172 because of a dead battery and bad alternator. I have lost coms a few times in my glider because of a dead battery.
I've never had a radio fail in a way that a second one would work.
