the shkval control was always a problem since is started using FaceTrackNoIR.
Since the shkval is controlled over the HMS, it is really difficult to move the shkval to the correct position.
I can control the shkval with the 8way/hat switch on my flightstick.
this is pretty slow, but very accurate.
The xbox-stick jumps into that gap.
I rough position the shkval with the HMS. Depending on the distance to the target i use either the hat or the xbox-switch to finally set the position.
If i have a second target to fight, i can without using the hms zoom the shkval out, adjust the tv-screen reposition the shkval within less than one second. For the final touches, i use the hat-switch again.
I tried a lot with the the expo/curve function on the x-box-stick axis. This helps a lot, but it is still not as precise as the hat switch.. :(
i also added some "dead-zone" on the stick, to allow press the button without moving the shkval again..
anyhow, it works good now...
