the pro dont use gyros in their airplanes....as far as i know they are banned in any type of competition.....i never have used a gyro and never will....im learning the "true way" same thing with knife edge coupling, i dont mix...i do the mixing" with my brain and thumbs.... however if i was to compete i would have a mix for that, one less thing to focus on when trying to focus on flying doing complex aerobatic sequences... i have a mix for that on one of my planes, and its almost too easy
