We did the torque roll in the aircraft. We were not really that close to a stall. However the torque was very low and the prop started to turn slowly lower than 2000 rpm. Durning the demo the instructor let the aircraft get past 60 deg of bank. I think to scare me into not doing that, ever. I think it worked really well.

Basically you have to be pretty foolish to find yourself in that situation. So your right about probably not being able to recover. A lousy pilot would likely fight the roll with aileron and elevator. There are roll spoilers so it would likely stall a wing and make the situation worse.
