Finally got it downloaded and installed yesterday, and had some time to do some flying.  As expected, it's *very* pretty, but holy smokes is there going to be a huge learning curve!  Let's hope people start coming up with tutorials real soon.

A few questions.  I was under the impression you could change time/weather within a flight, is that possible?  I couldn't find a way to do either.  Same with changing aircraft, unless I enable dev mode.  Time compression, if I pressed r and then + or - nothing happened.

Welcome to the club 🙂 Move your mouse and a white triangle thingy will appear in the top middle of your screen. Mouse over it to reveal the quick menu. On the right side you will find a cloud icon for weather and time management. 

Hmmm, how did I not see that?

Well don't worry, I'll have a billion other questions.
