The "9.5S" variant specifically focuses on the controller. This isn't a cheap plastic gamepad. It is a fully functional Spektrum transmitter cloned into a USB shell. It has the same gimbal tension, the same switch placement, and the same weight as the radio you use at the field. When you flip the landing gear switch in the sim, your thumb muscle twitches exactly where it would on a real $400 transmitter.
Note: The included InterLink DX controller (sold separately as a bundle) feels fantastic. It has a compact feel but uses Hall Effect gimbals. If you buy just the software, you can use your own radio via USB or the WS2000 dongle. realflight 9.5s
