**3. Results**

In the following section, the results of all studies are shown. First, the calculation of the required VTP sizes for the four propeller and wiring configurations is presented, while the rest of the aircraft remains unchanged, negating the so-called snow ball effects resulting from changes to one or more aircraft components. As can be seen in Section 3.2, some configurations would require a huge VTP in order to be controllable. Therefore, only designs with realistic fin sizes are further evaluated in Section 3.3.
