Maybe this could be something for the film viewer?
The ability to see where stick, rudder, & throttle position are?
In AW you could do this...it was a small circle with a cross that was showing the full motion of the stick. Then it had another little cross that would move to show where the stick position was. You could also see the throttle and rudder settings to the side as well...this was just a simple bar with a line that would sway left and right from it's center mark.
I just think this would be great to those of us who are studying films and such while learning new birds.
Just an idea..and I'm sure it's probably been mentioned before.
Sure would be a handy tool for the trainers too I think.
