I have tried both linux and mac versions and simply cannot get either to work correctly.

They either crash or the controller does not function as it should!

Can anyone recommend an FPV sim that works?

Hi idnotl

Do you check the Sticky Tread on top.?

This Program cant handle negative values from the Transmitter.
I think it depends on what Engine this code was written.

You need configure your Transmitter, to send only positive Values.

I currently use the Windows version, and FPV Freerider never crashed.
2 years ago, i used the Mac version, and i cant remember some issues.

Do you can provide more information, maybe can help you, to solve the problem.
