 The Walter engines (all variants) have been used for years in the 3rd
 world European countries.  I am sure they have been used in pressurized
 airplanes.  What systems are they using to pressurize?
 
 There also seems to be many very satisfied Lancair PT owners/flyers out
 there.  Why the dismay at this point?
