I have been planning my first electric project, doing lots of research.
I want to build an EDF airliner, most likely a 777. Most guys I see building EDF jets use foam for building them.
Would a foam airframe really end up being that much lighter than a balsa one?

I was hoping to get a plane that has about a 55" wingspan and using Wemotec 730 fans. Am I dreaming, would this be possible?

This electric stuff is pretty confusing, I hate feeling like a newbie again
