Fuji, my stall warning is also on the right (low) wing. Being a tab/microswitch type, it's vulnerable to all sorts of 'precision' adjustments by well-meaning folk. Currently set very conservatively, but it barely matters: to get into trouble in most flight regimes you'd have to work hard to induce a stall, and then consciously ignore the aerodynamic signs. But I guess it's possible. Stats for RH/LH wing drop (if it happens) on power off stalls are about equal (checked after trim tab adjustments).
Incidentally, I notice the LSA version of the aircraft doesn't have a stall warning - and they don't seem to be dropping from the sky.
At least the tab type switch is checked without the suck test. I see a lot of people sucking vigorously on C172 etc reeds without the obligatory barrier hanky. Obviously don't have spiders like the ones in our hangar!
