The problem is that the launch drone is bigger than the drone. And it uses all the same technologies, the motors, the propellers. And the launch drone has to be able to move forward to give the plane drone enough velocity. Just replace the plane drone with some weapons or fuel, and you have a VTOL drone. The size is important too, instead of having a small drone, you have a small drone and bigger drone. You have to transport the bigger drone, when the whole point was to use a small drone. It would make sense to have a launch system. The ScanEagle uses launcher and pole to capture it on landing. Or drones that launch from runways with rockets, and then get caught by nets. But the VTOL designs mean that you don't need to any of that infrastructure. You pay a penalty in weight and maybe increased size, but that isn't a problem for these drones where flexibility is more important.
