If you're actually trying to scale aircraft up and down, you can do the math and figure out that a scaled down aircraft will be slower. It's a perfect comparison. A Tesla Model S doesn't have any more weight efficiency than a battery swapped sedan. It's just as heavy as a battery swapped sedan, it's just built to handle the weight better. The main factor in the Alice having a lower L/D is flying at less than half the airspeed and thus drastically reducing parasitic drag. There are no easy gimmes. You're going to have to sacrifice range and speed. So far electric airplanes are somewhat worse than piston aircraft. They will never rival jets until we drastically increase energy density. The turbine efficiency of modern turbojets is actually around 60% and there are turbines with more than that. The overall efficiency is actually lower because of propulsive inefficiency, but electric aircraft have that exact same problem.
