Best (stock) single engine prop with autopilot is probably the Beechcraft Bonanza G36
Or… .with a tiny tweak in the .cfg file - the VL3
(There is actually a mod vl3 posted right here in these forums - great plane. VL3 - Rotax 915 mod)
Managing cockpit view and nav map/ATC map pop ups on the same monitor truly sucks.
I try to keep the MSFS2020 native stuff to a minimum and even then I am running another monitor for the ATC popup. Those boxes truly just get in the way when you are trying to fly.
My solution is to actually use 3rd party mapping apps on completely different computers. - as long as the computers are networked then SimConnect passes the data.
LittleNavMap works ok like this. However there are also other options that use a browser and will even work on a phone or tablet.
