Hi, I am installing the panel and wiring in my QB RV8 and am embarrassed to say that I don't understand what the ES Audio board supplied in the stall warning kit is for? Clearly I am missing something quite fundamental here but I would have thought some kind of buzzer connected directly to the stall switch in the wing would do the job without any need for the board. This is my first post but I love this forum and have used it extensively during what is now 3 years of building with a while to go yet. Thanks Dave
