Yes. Exactly something like that.
Here is a YouTube video of what I my ideal setup would look like:
"A Cub in the Clouds". It is a documentation of a short IFR flight from Anchorage AK to Palmer AK in a CubCrafters FX-3 taildragger in conditions that probably could have been flown VFR (with some effort) but was much easier and safer as IFR. He has a nice Garmin IFR setup with a G3x touch, a GNC 355 IFR GPS/comm, a GFC 500 autopilot, and a backup G5. Everything is connected to everything. One beautifully integrated setup in a very streamlined package. There is absolutely nothing out of the ordinary about this flight except for the fact that it was conducted in a Cub type airplane.
Here is another equivalent YouTube from a different pilot flying a similarly equipped FX-3:
RNAV GPS Approach Demo in a CubCrafters FX-3
The beauty of this type of plane (for me, at least) is that it would give me the opportunity to develop stick and rudder skills in a "fun" aircraft
and to develop IFR skills using the latest technology. I wouldn't want to fly a plane like this in prolonged or severe IFR conditions but for the kind of flying shown in the first video it would be great.
