Regular spins are easy to get out of (Although the game has you use ailerons with rudder and you should never touch ailerons in a spin in a real plane). A flat bed spin though, from the theory of it would be impossible to get out of. "Recovery from the flatter of the two modes was usually less reliable or impossible. The further aft that the center of gravity was located the flatter the spin and the less reliable the recovery." Source:
http://en.wikipedia.org/wiki/Spin_%28flight%29. (also, I know that wiki isn't the best source...). This is a reason though that when we are practicing spins in real life, we do it in the utility C of G category which give an appropriate forward C of G so as to make recover possible.
