NOR/REVJe •• iE&!q)IJIIIIIJI!:~
Lift up the helicopter by hand, and turn it to the left (yaw). Check if the rudder servo is applying correct compensation to the
right. If reversed, set the NOR/REV setting as follow.
Setup method: Press and hold the SET button for 2 seconds to enter the setup mode, then press the SET button to select
NOR/REV setup mode, as indicated by the lighting of NOR/REV LED. Using the transmitter's rudder stick, select either NOR
(STATUS LED is green),or REV (STATUS LED is red).

There is a direct correlation between servos' speed to gyro's performance. Faster servos are able to execute commands from the gyro
at faster and higher precision. Oue to the high performance gyro sensors used in the 3GX flybarless system, premium high speed digital
rudder servos are mandatory for optimal tail performance. Some of the recommended rudder servos include Align OS650, OS620,
OS520, OS420, Futaba S9257, S9256, S9254, S9253, or other servos with similar specifications.
Setup method: Press and hold the SET button for 2 seconds to enter the setup mode, then press the SET button to select OS/AS setup
mode, as indicated by the lighting of OS/AS LEO. Using the transmitter's rudder stick, select either digital servo OS mode (STATUS LEO
is green),or analog servo AS mode (STATUS LEO is red).
