Default Mower Trimmer Mash-up

Ya know, I assumed (and ya know what happens when ya do that) the Flymo blades both cut the grass and provided lift. Then I turned the mower over.

Turns out there is a separate impeller, above the cutting blades, that does the lifting.

So, me thinkin' is that string weighs less than that blade...may offset the possibility that an AC motor could weigh more than this flyweight 2-cycle ICE.

Must send Igor in search of lightweight, high rpm motors that can swing string. Shouldn't be too hard to find such creatures. Maybe I just use a motor from an electric string trimmer. It will be swinging longer lengths of string than a trimmer, though. A bit of empirical testing is in order...
