Batteries....Lithium to be exact, with a new chemistry on the horizon that may make the same leap ahead of Lithium that Lithium made over Lead-acid.

May 28th a Cessna Grand Caravan flew for 30 minutes on battery only using about $6 worth of electricity. They are currently working to Make 100 mile shuttle fights with 3-4 passengers, with a 30-40 charge time between flights.

35 years ago when I was into R\C an electric model was good for about 2 minutes under power and about all you saw was poorly performing gliders because they were heavy, but less messy than nitro burners.

Most of the better drones can now hover with flight times in excess of 15 minutes.

I read an article a while back about a rental service that uses Teslas and is actually making money on them because the lifespan has far exceeded that of a gas car with less maintenance.
