Revomix tail pre compensation adds rudder in response to collective pitch changes when the tail needs increased holding Revomix is independent of the transmitter By default it is turned off the user must set the amount required and the direction of the pre compensation The correct direction is determined by the correction needed at full positive or negative pitch to compensate for the main rotor torque In most cases the main rotor rotates in a clockwise direction Allowed values are 10 to 10 with O being disabled in most cases it is not necessary to use this parameter however when using low headspeed or on helicopters with a poor performing tail this setting can be used 43 Pirouette consistency This parameter determines the consistency of pirouettes and holding performance If pirouettes are not consistent during certain maneuvers increase the value of this parameter This value is individual for every model it depends on many factors such as your rudder mechanics head speed etc Before setting this parameter it is recommended to first set the gyro gains If the value is too high the tail can oscillate or wag It can also cause poor stop performance This value should be between 150 and 180 For brushless servos it is recommended to increase value by 10 15 points 44 EXPERT SETTINGS For fine tuning you can set the following parameters Normally it is not needed to configure any of these parameters Stick de
