If you want a (relatively) fast low wing LSA kit you have many choices: Zenith CH-650, Vans RV-12, Rans S-19, Sonex/Waiex, etc. these have cruise speeds of 120-138 mph.
But if you want to build a high wing aircraft it looks like you're limited to a 95 mph cruise - 25-40 mph slower than the aircraft listed above. Instead they're designed for STOL performance.
STOL capability and bush flying are great if that's what you're looking for, but where are the relatively fast high wing LSA kits? Cessna's new 162 is high wing, and so is Flight Design's CT (the #1 selling factory-built LSA). Both of those have cruise speeds > 120 mph.
High wing aircraft have a number of advantages: Better downward visibility, more room & baggage space, easier ingress/egress, cooler in the summer, simple gravity-fed fuel system.
I'm not saying high wing aircraft are better than low wing, each have advantages. But why the big void in the marketplace? Do we have to accept a low cruise speed if we want to build a high wing aircraft?
