actually the games "default" stall horn / buzzer is very helpful, especially to newer players learning to turn on the edge of the stall and/or learning to maximize their plane's sustained turn rate
reason being is you can be turning your plane and be at the edge of the stall, it will start out as a very low volume sound buzzer, the more you take your plane into the stall the louder the buzzer will become, from low volume to medium low, to medium , to medium high volume, to high volume....
this is a great learning tool in learning how to ride the edge of the stall........ right along with riding the stall buffet, same deal. you will start out with the slightest of screen shake, the more you tighten the turn of your plane, the more abrupt the screen shake ( the stall buffet )
hope this helps
