There is a known bug that only allows user to use throttle, while other stick movements aren't working properly. The sim requires this windows patch to run the Betaflight scripts. Most people running on windows 10 will already have this, however if you are experiencing this issue, there is a resolve for it.
There are two options to resolve this issue:
1. The first option is simply to uninstall and reinstall the sim, The patch/file needed will auto update/install with the new install of the sim. However some have reported that this method doesn't work, while others have. If this does not work for you, please proceed to #2.
2. Please install the windows patch Visual C++. Close down the sim if you have it open and run this install. Once finished, you should restart your PC, launch steam and launch the sim. Here is the link for that.
Once you have installed the needed patch, if you are still having issues, please send us a help ticket, including as much detail as possible for the problem at hand. Here is the link to submit a help ticket.
