Warrior PA28-151 Stall Speed

[sanjiv]

I have a 1974 warrior and POH indicated VSo of 50 Knots where as all 151 or 161 post 1977 has VSo of 44 Knots. Can someone explain what changed between these models to call for such difference? I can think of aileron difference as mine has frise ailerons where as later models past 1976 I believe don't. Just curious to find out what else could be what changed in 1977
