That's not true according to Dustins video. he said that there is a dead band setting switch with two postions. One for digital servos and one for non digital. In my case that's not a problem, I have digital servos on all my flight surfaces in all my jets with one exception.

As Scott mentioned this airplane does at times do the "Sabre Dance" during high speed flight. A rudder gyro properly set should do away with all of that also.
