FlyThisSim, also known as Simavio. Interesting company. I bought their panelbuilder software in 2013. Turned out they used us as beta testers. When they ironed out (most of, the version they marooned us with still has some hickups and an incomple nav database) the kinks they stopped supporting the older version of the panelbuilder software and started selling complete sim setups. They still sell the panelbuilder software but added a zero to the price, now it’s around $1500. Software looks and functions exactly the same as the older versions but can be used with the latest versions of X-Plane11. Thought about getting the latest version for X-Plane 11 but it now looks dated compared to Air Manager, another consumer panel builder software. X-Plane 11 cost $50, Air Manager about $70. Tricked out game computer and touch screen with throttle, yoke and rudder pedals about $1800. So, for around $2000 you’ll have a desktop sim with the same IFR practice functionality as the $8,100 FTS system, just not FAA certified.
