FPV Freerider does not have the ability to read the values directly, it goes though Unity's input manager (That is used when developing the sim). I can only see that values that is coming through that input manager.
Is your Thrustmaster connected directly via USB, or does it have some other kind of connection/driver?
It is connected through USB - standard HID device, no drivers needed.
I also tested with Unity 5.6.0f3 and the behavior is the same. I don't think there is anything that can be done. Others have also stumbled upon this:

Alas there seems to be no solution.
Anyway ... I've hooked my RC transmitter through vjoy so I'll use that.
Best~
