one thing that helps by leaving the stall horn/buzzer on is knwoing that you are turning at the best sustained turn rate for the givien speed you are at.

If the stall horn/buzzer is blaring in your ears at a low to near medium volume that is the best turnrate for that speed ( NOTE* I am not saying the best over all sustained turn rate, just the best sustained turn rate for that speed )

If the stall horn/buzzer is blaring in your ear at medium to high volume you are actually hurting your turn performance and bleeding more E than needed and making a wider turn than you think you are.

This is a rule of thumb type deal for all aircraft, you could be doing 300 mph and the stall horn can be blaring at different volumes.

something to think about / remember

All of it is important; most of it vital; and all of it just too much for one brain to absorb in 1-2 lessons" TC

Just a note on your snap rolls.

A snap roll is an accelerated stall that normally combines an increase is angle of attack with a full slip and usually happens when flying a speeds less than normal cruise.

What's that mean? Yank the stick back and tromp a rudder and you can plan on stalling the wing first in that direction. Right rudder will stall the right wing first. It will either cause the plane to flip over on its back or all the way through a full roll.
The faster the entry the high forces on the plane but entering a snap roll at a slower speed will increase your chances of a spin.

If you're looking for the fastest snap roll its normally in the direction opposite prop rotation.

In order to understand all this you gotta realize a stall is not dependent on speed but reaching a critical angle of attack .
That means a stall can actually happen at any speed. Should you feel (I use that term loosely as you don't "feel" anything sitting at your computer terminal but you can "hear" the stall warning buzzer) the onset of a stall all you need to do is ease back pressure off the stick. That has an immediate effect of reducing angle of attack. However, if you ease back pressure then add it again you, once again, risk a stall.

Hope this helps.

My advice, buy a Force Feedback stick... You can always feel the stall coming on and ride the edge of it very easily...
