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 ?
