Effectively 100% of high end or extreme heli flying is done with flybarless helis using 3 axis gyros. And those maneuvers are effectively impossible for most of us to perform! The skill levels are outrageous and they use gyros. And they compete with gyros.
I am not sure a good flying pattern ship would really benefit from a 3 axis gyro. I don't know yet. But flybarless systems and 3 axis gyros have revolutionized heli setup and made it easy for everyone to have a good flying heli so airplanes could probably benefit also.
A great video for learning snaps and many other maneuvers is the Andrew Jesky Osiris construction setup trim and flying video put out by Higher Plane productions, Precision Flight Volume 3, I know 3DHS has it. I wonder what he would have to say about all this?
