As far as I'm aware models and full scale aircraft can't be compared due to scale effect, lower Reynolds numbers, huge props etc. Models can do things the real aircraft can't... its the same reason we can't make a Cessna size model of a hummingbird - scaling it up cancels out all the advantages. And as Genghis showed with my little concept, the simulator and real life don't always compare well.
(Although the MCR01 Ban-Bi shows 30% higher numbers then Genghis quotes, it's not really a typical microlight)
In theory, the higher the normal wing loading the faster the top speed, also you'd be able to make a low AR wing stiffer and stronger. Of course there'd be higher landing speeds and a rougher ride, but that's one of the many compromises
