Tip, don't be a complete dumbass
Why are you so bent on not refueling? You are talking about a couple hours recharge time for your imaginary fleet anyway, sheesh! Then after 1000 launches you can go buy new batteries for all of them. Your specific example is just stupid. Escpecially since this is a hybrid thread and you are still going to have to refuel the stupid thing anyway.
If you want a sailplane that can self launch, and has ready fuel then buy a motor glider and go to an airport that has fuel. You make too many problems for yourself, but they are your problems. I don't really care about the nuances of your imaginary amusement park. There are people and cargo to move long distances.
