if you're brave you can desoilder the throttle stick thing of malooo to remove the return to center spring.

Trun off the fix camera posistioning. The 2.8 version allows you to do so. But as a default
it's set on ON.
It will make it feels more like you're flying a rc sim and not a vedio game feel,
becuase the model will float all over the screen. Notice how the other sims dose that.
I guess making a photolistic scenery helps too.lol

Turn off auto focus unless you have special eye balls that'll do that too.

The 2.8 version also has has a parimeter. this allows you to set different perimemters for a model.

A lot of it also has to do with camera/pilot posistioning.
To adjust that just use NOTEPAD to open the .scn files.

notice how the model dosen't stay fixed to the center of the screen.
