Yes that is correct you do have to keep after the tail. In a true rate gyro, revo is great but as far as setting up for flying rate mode with a HH gyro, why pay the extra money for a 401 that your going to run in rate mode. The only real exception to this is some of the scale guys prefer rate mode for a more scale flying look but truthfully it forces you to learn to fly the tail and you'll be a better pilot, fixed wing included by learning to use the rudder.

There are those that prefer symetrical pitch throw setup but in reality, with the 401 its best (IMO) to center the servo at hover pitch, set throw with the limit pot on the gyro so that there is no binding in either direction. Seems weird but..........when going right your fighting torque so you need more throw. When going left your just taking enough pitch out to let torque do the work for you. If you set it up this way you won't have symetrical throw but you'll have symetrical piro rates.
