There is always a trade-off, we spent a lit of time looking at landing and recovery and opted for VTOL because we just don’t have suitable areas for autonomous runway landing and takeoff. Also the density of the vegetation means that wingspan is a big consideration because you have to cut and maintain clearings for VTOL. We opted for for a maximum wing span of 3m and an optimised flying speed of between 45-60kph. We traded faster flying speed for giving an AI more time to recognise targets in difficult scenarios. We also optimised the design for endurance.
