To change the linearity,
highlight the required position (Pos-0 LIN, Pos-1 LIN or Pos-2 LIN) by rotating the Scroll Bar
and click on it to bring up the sub menu choices. The highlighting is surrounded by a box to indicate that it is selected. The
right hand side of the screen displays a graphical representation of the response curve. Rotate the Scroll Bar to alter the
setting. With the control stick at neutral, the figures for both sides of neutral change together. If the control stick for the
channel being adjusted is moved from neutral, the adjustment changes only for that side of neutral and only one figure is
highlighted or changed. To return the figures to the default of linear (LIN), press the clear (CLR) key at the left hand side
of the screen. When the required setting is achieved, click the Scroll Bar to exit the sub menu.
Press the LIST key to return to the Function Menu. Press the enter (ENT) key to return to the Information Display Screen.
Servo Reverse
The Function Menu List is accessed from the Information Display Screen by pressing the LIST key. From the Function
Menu List, rotate the Scroll Bar to highlight the "REV.SW" menu choice and click the Scroll Bar.
Please note that the
screen display will depend on the selections made in System Mode - DeviceSEL and Wing TYPE.
To change the channel movement direction,
highlight the required channel by rotating the Scroll Bar and click on it to
toggle between normal and reversed. The black direction indicator square moves between the top of the box (reversed) and
the bottom of the box (normal) to indicate the current selection. When the required setting is achieved, click the Scroll Bar
to exit the sub menu.
Press the LIST key to return to the Function Menu. Press the enter (ENT) key to return to the Information Display Screen.
Sub Trim
The Function Menu List is accessed from the Information Display Screen by pressing the LIST key. From the Function
Menu List, rotate the Scroll Bar to highlight the "Sub Trim" menu choice and click the Scroll Bar.
Please note that the
screen display will depend on the selections made in System Mode - DeviceSEL and Wing TYPE.
The Sub Trim feature can be used to dial out small inaccuracies in the servo or transmitter settings and so modify the
neutral position of a servo so that the arm is exactly at right angles to the direction of movement. It is usually best to
position the arm as close as possible to the correct position and use only a small value of sub trim. As servo movement has
a maximum of 150%, large sub trim values will restrict the amount of movement on the sub trimmed side of neutral.
Sub trim values of between ±250 (or left/right/up/down 250) can be set corresponding to about 70% of servo travel.
To change the sub trim value,
highlight the required channel by rotating the Scroll Bar and click on it to bring up the sub
menu. The highlighting is surrounded by a box to indicate that it is selected. Rotate the Scroll Bar to alter the setting. To
return the figures to the default of zero, press the clear (CLR) key at the left hand side of the screen. When the required
setting is achieved, click the Scroll Bar to exit the sub menu.
Press the LIST key to return to the Function Menu. Press the enter (ENT) key to return to the Information Display Screen.
