SuperCub uses a retractable leading edge slat on their wing that still lets them fly at around 20 mph. I believe there are no complex cables and controls involved. It works on air pressure, and under 60 mph, it opens up, while speeds over that, it retracts which gives considerably more top end airspeed and economy. Many STOL aircraft didn't won't to use retractable leading edge slats due to it often making the system much more complex, but this doesn't appear to be the case with these. Their site doesn't seem to have too much in the way of details from what I've found thus far, but I'll keep looking. I'm guessing this is accomplish through springs? Anyone know?

I wrote Wayne at SuperCub, who said although the Zenith aircraft hasn’t ever contacted him, he says it would be a fairly simply process to adopt them to their planes as well.

Might give the Zenith 701, 750 and 801 crowd, and other STOL aircraft something to think about.
