The issue is that you do NEEd air in order to use the props. So there is a limit to how high you can go. Air resistance vs not having enough air to push. Bas

Basically - you can design the prop for high altitude, but then takeoff is gonna not be great. You could design a variable prop system (or even have 2 different ones?) but then weight / complexity.

- nickik 6y agoIf you go supersonic you get enough air in even when flying higher. His plane is VTOL so the overpowered engines for supersonic will work well for liftoff.
