I don't really know why, I've just always been drawn to unusual designs, the flymos are certainly that. They also seem to be even thinner on the ground than the twins.
As a school boy I grew up with knowledge of the first hovercrafts.
https://en.wikipedia.org/wiki/HovercraftSean, The first hover lawnmowers were Flymos - and they embraced the design
in a whole new application - a mower that could float on air.
They have retained a niche market these days - mainly for slope work.
Early examples remain largely un-recorded. I have written about them here:
