How to X8 coax with Quatos

[plexus]

Hi,
I dont know how to find the position of the motors on the arms with quatos.

I build an Coaxial X8 in +. In the quatos air frame geometry i have a doubt to declare the position of the motors on the arms.
how to write the position of the motors in +Z and -Z (upper and below the arm).
See my config:

<?xml version="1.0"?>
<!-- Distances in meters
Wieghts in grams
+1 == CW rotation
-1 == CCW rotation
-->
<quatos_configuration>
<craft id="X8coaxial" config="custom">
<ports>
<port rotation="+1">1</port>
<port rotation="-1">2</port>
<port rotation="-1">3</port>
<port rotation="+1">4</port>
<port rotation="+1">5</port>
<port rotation="-1">6</port>
<port rotation="-1">7</port>
<port rotation="+1">8</port>
</ports>

Can you help me

Thanks

Hi max,
May thanks for the help? I changed my geometry by this one. I am in quad coax plus 8 motors
<quatos_configuration>
<craft id="quad_coax_plus" config="custom" motors="8">
<geometry>
<motor rotation="+1" port="1">1,0</motor>
<motor rotation="-1" port="2">1,0</motor>
<motor rotation="-1" port="3">0,1</motor>
<motor rotation="+1" port="4">0,1</motor>
<motor rotation="+1" port="5">-1,0</motor>
<motor rotation="-1" port="6">-1,0</motor>
<motor rotation="-1" port="7">0,-1</motor>
<motor rotation="+1" port="8">0,-1</motor>
</geometry>
</craft>
Is that config good ?
Alain

Hi Kissys,
Thank you for the help, that is correct now.
Maybe to add a remark in the wiki about the X8 coax.

A note regarding what, where? Also, an "X8" flies in X config by definkition, which is why i pasted the octo coax X config. But good job finding the right mix.
