The merest light turbulence would upset the flight requiring re-leveling the wings with the rudder, it was like flying a leaf. Top speed was about 90 Kts.

Of course, I heard "wing moan" many times in the rotten weather I would sometimes push through. Top speed was about 170 Kts My Lancair 320 has a loading of about 25 ppsf and rides thru moderate turbulence no worse than a Corvette on a rough road. It doesn't get upset, but it is harsh sitting on the main spar. Top speed is about 200 Kts. Small thin wings = low drag = high performance = high wing loading = more resistance to micro-shears (turbulence). Just ask any Mig 19 pilot.
