Let me explain this just one more time. All aircraft have a stall speed, Cessnas about 45 knots, Airliners about 110 knots. You have an attitude indicator to make sure you don't pull up into a stall so keep it about 2 degrees nose up max in both planes. Keep adequate power above cruise power and you will be fine. If you choose to pull full back you won't. Most competent pilots will understand this in their 5th hour. We all did.
