Don't be afraid about the buttons amount, realize that the options manager allow you to set each clickable command in the cockpit and more(and it will be totally useless most of the time), but when you only keep the HOTAS, engines commands there's actually not that much to do. Don't be scared that just a list guys!
Btw, the T Flight is a good HOTAS, add at least, set one modifier and you can multiply your hat.
Have fun!
