I downloaded and installed Milton Shupe's latest Aero Commander, file name AC560AV. It's a terrific plane, but I am having one problem, and I wanted to know if anyone else is experiencing the same thing. I can't tune (manually or automatically) the Nav 1 radio. It seems to be stuck at 110.50. I checked the docs, but they indicate normal operation. I don't know if it's a problem with my installation, or if it is in the file itself.Joe LaBracio

You have to do it on that rotary gauge up on the glareshield. I think it defaults to "10.50" which is the same as 110.50. Rotate the knob in the lower right (I think) to set the desired frequency. The pop-up digital panel is only a conformation of what's set on the real radio.

Thanks, I'll give it a try.
