When watching real plane videos saw Lancair planes and found one in FG. It is a lovely plane to fly. However there appears to be an issue with the KAP 140 when in VS mode it doesn't capture the target altitude either up or down. It simply doesn't stop at the inserted altitude. Also when the Nav1 frequency is set and in range there is no audible. Lastly when trying to work out how to use the ILS function I came across this video and frankly this guy made it so simple to understand the use of APR button. https://www.youtube.com/watch?v=5j_hGqzxGvc Sounds quite young but knows his stuff.
Just thought I'd ask when you use the REV button is the plane suppose to descend as it does on APR. I tried REV and it worked picking up signal and redirecting plane to airport but didn't descend from 2000ft.
