Okay, but how does all this relate to the standard stall warner as supplied 
by Europa. An adjustable low-pressure switch which goes ON when pressure 
changes to vacuum at the bottom of the leading edge. Very simple, cheap, and 
should work at all speeds and attitudes, except maybe when inverted. Am I 
wrong here ?
