{{DISPLAYTITLE:SETUP MENU J - Servo trim|noerror}}

{{TOC_BXFbl|Manuals:BXFbl:Setupmenu_I/en|Manuals:BXFbl:Setupmenu_K/en|SETUPMENU|}}

<br />

At SETUP MENU point '''J''' we trim the servo center positions so that each servo horn forms an exact 90 degrees angle with the adjustment linkage. This is necessary as usually you will not be able to attach the servo horns in exact center position to the servo.<br />

<br />

<br />

There are two options to trim the servos. First you can trim each servo position individually. Additionally you can trim all servos together moving them on each flight control axis. This especially can be handy when later on the flying field, i.e. to trimm the collective, or in order to trimm pitch and roll in case the heli is drifting to one side.<br />

<br />

<br />

Initially the trimming is 0 for all servos. In this case the Status LED will be off when entering Setup Menu Point '''J'''. At first, attach the servo horns to the servos in this position. So you will make sure to get roughly equal throws to both directions. Mount the servo horns so that they form a 90 degrees angle to the linkage rod as close as possible. Then in the next step, you can fine trim every single servo‘s center position, as usually mounting the servo horns at exact 90 degrees will not work out perfectly, depending on the servo gear trains and the servo horns.<br />

{{SHORT_QUOTE|width = 90|margin=10| If you don't like that servos move up/down on selection, i.e. when using a swash leveling tool sitting on the swashplate, please use StudioX App to trim the servos.}}<br />

<br />

<br />

If necessary, you can also trim the swashplate at once. For this push and hold the button for at least 2 seconds when at SETUP MENU point '''J''', then release. The servos will move in a circular manner to indicate the trimming mode has changed. Now you can trim the swashplate into each direction by tapping or holding aileron/roll or elevator/pitch. The collective can be trimmed up and down using the rudder stick.<br />

<br />

<br />

To reset the trimming and set all positions back to zero, push and hold the button for 10 seconds or more. When the yellow menu LEDs start to cycle in a loop, release the button.<br />

<br />

<br />

Trim each servo using the '''+''' and '''-''' buttons so that the servo horns form an exact 90 degrees angle with the linkage rods. Then make the mechanical adjustment for the linkages as described above if necessary.<br />
