You can fit a Jetson Orin Nano on a winged drone. It has plenty enough power to run a vision model.
Given that the drone is going on a one way trip, I imagine you'd want to use the cheapest hardware possible which would mean using the dumbest model you can get away with.
Not just winged drone, we have had jetson on far more smaller 7in multirotors, plus other boards for network etc.
