I guess I'm dating myself but I remember this argument in the helicopter community, banning gyros at the nats was a hot topic discussion for a while...

Now you don't see a helicopter without one, hell most of the pilots today probably don't think you can fly a heli without a gyro on the tail and 3 axis FBL units are becoming the norm.

The FBL technology has made projects like the big 6 blade Sky Crane, or 4 blade Apache managable projects instead of one and done beasts.
