100 kg of fuel and 50 kg less on the engine weight allows for a lot of batteries. Not sure what is the flight time, but if someone can help with energy density

100 kg of fuel and 50 kg less on the engine weight allows for a lot of batteries. Not sure what is the flight time, but if someone can help with energy density we can calculate the exact number. I wildly guess it is more than 1 hours, but definitely less than 6 hours. Later edit: I did some calculations, the result is less than 30 minutes.

Not as bad because of the higher efficiency of electric engine. But yeah, 1 hour or so.

  One hour is quite enough for taxi-type and drone delivery. Also, you could use structural batteries, which would substitute for part of the plane structure.
