I don't own a Turnigy Evolution myself but I think it should be plug and play, connected via USB. Might depend on what operating system you are running it on. Make sure you don't have vJoy or Smartprpoplus installed when connecting via USB, that might mess things up. Let me know how it goes.
Thank you very much for your answer!
Actually I have no clue how to connect the Evolution to the computer. If I plug it in, nothing happens (no sound or anything in the device manager). Could this be because of SmartPropoPlus? Shall I deinstall it?
Update: Tried to deinstall SPP, didn't help. I actually think that the USB on my Turnigy Evolution is broken. =(
