So while a battery can put out a lot of power for a given weight. Power = energy/time. The range of EVs are severely limited.

You can optimize for electric power. There's a lot less cooling required, so there's less cooling drag. Electric motors are more easily configured to use slow turning, large efficient props.

Dale - dumb question, but why haven't you used larger props on the eLazair?


p.s. the cafe stuff is great reading. Google the name Klaus Savier. He got a vairEZ to go something like 260 mph on an O-235.
I'm going to assume the prop size was selected to provide the best performance while keeping the Amp draw in check.
