If we kept the engines for drag, use electricity to spin the propellers, would it work?

Question

The battery and its weight is a different matter, if we solved that, then would it work?

Answer 1

Keep the engines for drag?  What do you mean?  You will rephrase the question.

Answer 2

Wouldn't work well at all.

Answer 3

Of course an electric aircraft would fly, but present technology is inefficient due to weight of having a gas engine, a heavy generator, a heavy electric motor and a battery bank.

However, many model RC planes use small electric motors and battery packs.

The concept works in theory

Answer 4

That's how cruise ships work.  Electric motors drive the props, and they have generators to make the electricity.  Of course, you are probably talking about aircraft, and they are a bit lighter than most ships.
