Ray i fly the phenom a lot, the fly model if you respect de speed of tables is very good, when you climb the plane have a lot of power 22000ft aprox. The G1000 is sensitive, if you go for example to put the route and pass the point when you try to come back the sistem go crazy, you need put the plane to cold and dark and restart not is critical, put the flyplan step by step and no problem. In my opinion is the best modern private jet on p3d now.
If you have any questions tell me or send a PM im pleasure to help you.
Sorry for my english man.
