Loving your videos.
One video I would love to see is a minimalist IFR setup using a g3x and an autopilot.
In other words, what is the cheapest setup using the g3x without bells and whistles that would be ifr compliant with an auto pilot, for someone who doesn't mind doing a few things manually.
There's nothing like that on RUclips that I can find and builders on a budget would find that useful.
Maybe even a comments section, describing how this setup could be updated as funds become available, and what to prioritise first (based on your experience)

Porque não postar um vídeo mostrando o passo a passo dos procedimento para configurar o Rnaves no G3X ?

Another great video Adam, fantastic company!

[@kevinphillips9408]

Thank you for this information

[@chrishudson747]

Excellent. Thanks.

[@tnflygirl]

I can’t get enough info about the G3x as I’m trying to decide to upgrade. Thanks for the videos!

[@aladincarpetcleaning6416]

A lot of information, however could go a little slower for everyone to take in on technical setups. Great content!

[@MidwestPanels]

Thanks for the feedback!

[@JohnathanMaravilla]

Seemed to be speaking at a relatively normal/moderate pace. RUclips does provides the option to slow down (and speed up) the video, in case you were unaware of that feature

Gostaria de receber o passo a passo da configuração do RNAV do G3X.

Does the VNAV only work on a GTNxi or also on the older GTN’s?

[@MidwestPanels]

It works on the original GTN with Software 6.5 and up.

@@MidwestPanels thank you for the info

When using the GTN for VNAV, when setting an altitude target at a waypoint, is the VNAV Direct selection an essential step? I've usually just done Save at that step. Though, more than 50% of the time, the VNAV fails to properly engage, so I wonder if this is the reason. Awesome video, as always!

[@MidwestPanels]

The VNAV Direct-To is technically intended for use on a later waypoint (think of it in the same way as if you got cleared to a certain waypoint in your flightplan that was 2 or 3 ahead of your current waypoint), but I found that if I just do it at the first waypoint with an altitude constraint, it allows for 100% reliability in picking up and tracking the vertical course - especially when you're starting off-course laterally.

[@MidwestPanels]

One thing you can do is verify that a TOD point is shown on the G3X and/or GTN map page. If this is missing, then VNAV will not work, then you can do the VNAV direct-to in order to force it.

[@CraigMaiman]

@@MidwestPanels There's always a TOD point displayed when I set a waypoint with an altitude constraint (and it even seems queued up in the AP), but it usually just flies right past it. The bug is set to the lower altitude, so I feel like I'm doing everything right, but no joy...

@@CraigMaimanDid you arm the VNAV on the GFC507 and ensure that you see a white VNAV on the “scoreboard” (AFCS Status Box)?

[@CraigMaiman]

@@OneAlphaMike Yes. That's the thing that perplexes me! It looks all set, but no joy. Just flies right past the TOD and nada. Very strange.
