9.7.1. Transmitter Calibration
In order to make better use of the stick Rate and EXP of the gyro, a manual transmitter calibration is recommended to
perform in this page. You don’t need to calibrate the [AIL2] and [ELE2] channels if they are used as pass-through channels.
Step 1: Neutral Calibration for [Gain] and [Mode]
Move the mode switch and gain control knob (or slider) to their center
positions, the progress bar [MOD] and [GAIN] should be in the right position of 0%. If not, adjust the Sub-Trim setting of
your transmitter to fix it.
Step 2: Travel Calibration for All Channels
Move the sticks, mode switch and gain control knob (or slider) for each
channel to its full left or full right position, the progress bar should be in the right position of +100% or -100%. If not, adjust
the left or right travel setting of the corresponding channel to fix it using the End-Point or Servo Travel setting function on
your transmitter.

SERVO SETTINGS
[1] Servo Monitor
The servo monitor displays the servo positions for each channel graphically and numerically. The three red lines on the
progress bar represent left travel limit, center position and right travel limit from left to right.
[2] Sub Trim
The sub-trim function is used to adjust the servo neutral position, and to make fine adjustment to the control surface
after linkages and pushrods are hooked up. The neutral adjustment can be varied from -125% to +125%, corresponding
to pulse length of 1520
±
250uS. The sub trim setting is not available for the pass-through channels.
[3] Travel Limits
Travel limits can be varied from 0% to 150% in each direction of the servos. The default setting is 130%. It’s used to
protect the linkages, for example, if you have set the stick rate to 100% for aileron, after superimposing the correction of
the gyro, the final amount of the movement of the aileron servo(s) may probably exceed 100%, which could cause
damage to the linkages and pushrods. But after setting a
certain limits the total movement of the servos will be
limited in a safe range. The travel limit setting is not
available for the pass-through channels.
[4] Servo Trimming
This function allows you to fine tune the servo neutral position using the transmitter. For more details, see Page 25.
[5] Travel Limiting
This function allows you to adjust the travel limits of the servos using the transmitter. For more details, see Page 26.
