Dusty_B, Yes the load factor can go up to 1.41 which raises the stall speed approx. 19%.
And GA typically flys the approach around 85% of gross which lowers the stall speed 8% yielding a 9% increase in typical GA SE a/c.
stall speed varies with: root(LF) x root(weight/gross)
You can load up the back seats with fellow pilots and go up to 5000 AGL and see just how much biceps is required to stall out of a coordinated descending turn to final.
Yes, it is much easier to stall out at rearward CGs, but will still take considerable muscle in your average standard airworthiness certified spamcan and is much harder with just one or two up front.
