Any engineering involves trade offs. If you want a maneuverable bird, there goes the stability. You want armor? There goes the speed, rate of climb and ceiling. Kick it the butt harder. You just lost range. More fuel? Back to the loss of speed. I think they are trying to make the F-35 do too much. A fairer automotive comparison would be to call it a family sports pickup. Think of how poor it would be at all three tasks not to mention the dismal fuel economy.
A 450 lb battery used to store the equivalent of a gallon of gas worth of energy. It doesn’t pass the laugh test.
