Hi Kevin,

yes, In order to simulate an aircraft, you need a mathematical model for it.

The JSBSim FDM back end of NPS uses XML files to describe the aircraft (set via NPS_JSBSIM_MODEL).

So you need to create such a model (in conf/simulator/jsbsim/aircraft), refer to JSBSim docs on how to create JSBSim models.

Regarding AUX3: as I said you have to first create a command, then assign this command to a servo, see https://wiki.paparazziuav.org/wiki/Airframe_Configuration#Commands

e.g.

add servo named BAR

<servos>
  ...

  <servo name="BAR" no="5" min="1000" neutral="1000" max="2000"/>

</servos>

add command named FOO

<commands>
  ...

  <axis name="FOO" failsafe_value="0"/>

</commands>

assign command FOO to servo BAR

<command_laws>
  ...

  <set servo="BAR" value="@FOO"/>

</command_laws>

set command FOO to value of radio AUX3 channel

<rc_commands>
  ...

  <set command="FOO" value="@AUX3"/>

</rc_commands>

Cheers, Felix

@ Felix: what exactly do you mean with a model? I guess a mathematical one?
But in which format? And how to implement it in Paparazzi? Sorry, lots of
question at once.


Have a nice Sunday,

Kevin

PS: I still could not figure out to use my AUX3 Channel for  a Servo
movement. Pitch works for example. Just the AUX3 does not...
