Imagine if you could run your FPV with this: Saitek X-65F Combat Control System USB Joystick http://www.saitek.com/uk/prod/x65f.html With all those knobs and buttons you would never have to take your hands off the sticks.
Had not seen that one yet, I was looking at the Logitech system a while back: http://www.logitech.com/en-us/gaming/joysticks/devices/5855 And there is this to hook it up to your plane: http://www.nghobbies.com/cart/index.php?main_page=product_info&products_id=486
I like that one a lot better. It seems you don't need a PC. Very cool. This video demonstration is nice:
