shows that any airplane stalled at 1*Vs will attain 1 g, 2Vs 4 g's'
3Vs 9g's 4Vs 16 g's etc. if you give the plane a stalling incidence at 4 times the 1'g' stall speed you'll subject the plane to load far beyond even ultimate loads that goes for F16s too!!!
Note: a snap roll is really more of a a horizontal spin not stall
Sadly, it's not quite that simple. A plane which stalls at 1'g' at 100knots will likely stall before 4'g' at 200kts, even though 200=2*100, because the stall speed is also in practice affected by Mach number as well. Therefore you can't calculate Va directly from the 1'g' stall speed, certainly not for any aircraft which operates at fairly high speeds.
