trims will be converted into subtrim values, and the trim positions shown on the ‘Home’ pages will
all be returned to centre.
Note that InstaTrim (controlled by the switch selected as ‘Trim Switch’) offers another approach to
trimming by converting stick positions to subtrim in flight (see page 20). The two methods are
complementary.
Curves (page 7/13)
Curves tell your servo how to move in response to your stick movement. In ErSky9x there are eight
5-point curves and eight 9-point curves.
A 5pt curve is a curve you can edit at positions: -100%, -50%, 0%, 50%, 100%.
A 9pt curve is a curve you can edit at positions: -100%, -75%, -50%, -25%, 0%, 25%,
50%, 75%, 100%.
Curves CV1 to CV8 are 5-point, while CV 9-16 are 9-point. Here is an example of a 5-point curve:
Scroll down to the curve you wish to modify and press MENU or RIGHT. This will bring up the
screen for editing the curve:
You will see 5 or 9 editable points with the values initially set a zero. Scroll through the points with
UP/DOWN. Change the value with LEFT/RIGHT.
If you select the “PRESET” entry, pressing LEFT or RIGHT will populate the values with a linear
curve (i.e., straight line) that is a good starting point. LEFT gives lines sloping up from left to right.
RIGHT gives lines sloping the other way. Pressing the key repeatedly changes the slope. The
individual points can be edited by highlighting, pressing MENU and then using the RIGHT/LEFT
keys to adjust the value. Press EXIT to navigate to the next point.
The graph will show the shape of the curve as you edit the points.
