Now that i think that i understood what a quadshot is doing (in code) i came to the conclusion that i don't like this approach.

What i would like to do is to build an airplane that can ascend and descent vertically and not a multicopter that can fly at 90 degrees.

Now my question is this, does the paparazzi autopilot code for fixed wings have a problem with commands like the ones below provided that i can also change the elevons behavior just like in the quadshot airframe file depending in what attitude i am in?

Is the roll axis maintained when the airplane climbs vertically or it switches with YAW?

when using two motors YAW can be controlled with motor thrust when flying level.

      <attitude pitch="90" roll="0.0" throttle="1.0" until="GetPosAlt() > GetAltRef()+20" vmode="throttle"/>

<go alt="(ground_alt)" approaching_time="0" climb="-0.5" from="TD" hmode="route" pitch="90" throttle="auto" vmode="climb" wp="TD"/>
