VTOL airplane question

Chris Efstathiou
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.

     <block name="Takeoff" strip_button="Takeoff (wp AF_NORTH)"
strip_icon="takeoff.png">
       <exception cond="GetPosAlt() > GetAltRef()+25" deroute="Standby"/>
       <set value="TRUE" var="autopilot.launch"/>
       <set value="0" var="h_ctl_disabled"/>
       <set value="0" var="autopilot.kill_throttle"/>
       <attitude pitch="90" roll="0.0" throttle="1.0" until="GetPosAlt()
 > GetAltRef()+20" vmode="throttle"/>
       <deroute block="Standby"/>
     </block>

and

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