Without a doubt, the GoFlight GF-166 VRP (Versatile Radio Panel) Module is the device
of choice for simulation of radios in the sim cockpit. Designed to look and
operate like many of today's real-world NAV / COMM counterparts, the GF-166
offers sophisticated looks and an unprecedented level of functionality in a 2"
tall rack-mountable configuration. Real-world pilots will instantly recognize
the control layout of the GF-166, and flight sim enthusiasts love its realistic
look and feel.
For FS2004 and For FSX and For X-Plane and For Prepar3D.
