Thanks for all the tips and the link, much appreciated!
I use FEX, which I purchased before REX was released, and it works just fine. So far, I've been reluctant to switch, although I might be tempted, eventually... Both products do a lot for the immersion factor.
I have no real-life flying experience, and in FSX, I typically fly small aircraft: C182 RG II, recently started practicing on the Seneca (both from Carenado), plus my absolute favorite: Aerosoft's BeaverX. I usually use the built-in planner for simple routes, but it's not that good for long-distance IFR flights.
I know navigation computers are simulated on the more complex models, I actually have the CaptainSim 757 (couldn't resist as it was on sale), but flying that plane properly
above my current skill level...
BTW, if you don't mind me asking, what aircraft do you fly in real life?
