As batfink was saying, its all about timing of you control surfaces.  I was applying rudder and opposite aileron to keep it straight, then I cut throttle when very slow to help fight the torque.  I set the plane up to stall like that before i reached the 20mph mark, by 75mph or so, the plane is already stalling and further inputs do very little.  
Of course, a little luck go's a long way.  As I said before, the mossy can get into some ugly stalls.  Sometime you can get into a nasty upside down flat spin, which I have trouble recovering from.
