To add to this, I wanted to post a report on this as well, but I think it fits under this report perfectly.

When one binds different keys to the control scheme, even then the controls do NOT work as intended, for example:

I use Left arrow, Right arrow, Up arrow, Down arrow, for Collective raise/lower and Spinning left and right.

I use Q and E instead to switch the rudder.

Pressing right arrow banks me rightward, even though there is NO SUCH KEY OR OPTION IN THE CONTROL SCHEME.

pressing E makes me tilt forward, even though there is NO SUCH OPTION OR ANY ERROR MESSAGES/WARNINGS STATING THE KEY IS ALREADY IN USE.

Needless to say this makes me crash my helicopter every single time and, frankly, flying with a keyboard has hence been nearly impossible.
