Have you tried the no-flap scenario?
There are sufficient real life data available for the DC9/MD80 leaving ground effect into a stall.
Quoting lomapaseo:
From what I have seen with numerous DC9 series takeoff stalls (many due to ice on no-slat aircraft) the biggest problem was the loss of lateral control and/or roll just out of ground effect. True the aircraft may climb but not all the wings wish to follow and once you catch a wing tip it's all over.
