e) Basic Trimming "Sub trim"
As previously mentioned when installing the servo, always mount the servo stick at a 90° angle to the linkage rods
(see fig. 12). The trim displays at the transmitter (see fig. 5, items 6 - 9) should be in the centre position. Only then will
you be able to perform fine trimming in both directions using the trim buttons during flight (see fig. 1, item 6, 8, 15 and
17).
However, the cog teeth on servo sticks are often so large that the exact 90° angle cannot be set. This is why the basic
trim helps to set the correct centre position of the servo arm without the need to adjust the trim buttons.
Important!
Before setting the basic trim, check with the operating display whether the four trim displays are set centrally.
Setting the Basic Trim
• Switch on the transmitter and call the function setting menu.
• Move the cursor arrow to the menu item "Sub-trim" with the scroll wheel.
• Briefly confirm the scroll wheel button or the button "OK" to activate the
menu item.
In the display you will see display items for the six control functions with the
respective currently set trim values.
• Turning the scroll wheel can now set the basic trim for channel 1.
• When pushing the scroll wheel button, the cursor arrow will jump to
channel 2. Turning the scroll wheel now permits setting the basic trim for
channel 2.
• Repeat his process until you have set the desired basic trim in all six
channels.
• Push the button "OK" to save the settings. The display then shows the
function setup menu again.
• Push the button "CANCEL" repeatedly until you get back to the operating
display.
