Ryan,
I've had my L-2 for 6 years. They are extremely docile airplanes. The issues the Army had were a series of fatal crashes while landing. Specifically while making circling approaches and the pilots getting too slow and stalling while in turns. The L-2 stalls abruptly and, if banked over, wants to go onto its back. I've tried this a few times at altitude.
The L-2 has very little washout compared to a L3- or L-4 so is a little less well behaved when stalling. The trade-off is that an L-2 will walk away from it's L-bird siblings. Cruise is about 15 mph faster.
Flown properly, the L-2 offers little in the way of surprises. Before stalling there is plenty of warning. The plane wants a lot of aft stick, there's a bit of buffetting and the controls get very mushy. Finally it gets eerily silent in the cabin. At this point you're probably about 1mph away from stalling.
