 Scott,
 
 The poor baffling is not just the IV-P series.
 
 The Columbia certified airplane is one of the worst baffled normally
aspirated airplanes around.  The fuel set up is also poorly done on that
certified airplane & engine.
 
 By contrast,  the Cirrus is pretty well done with a couple of glaring errors.
 
 If you want to see a well done baffling job,  then take a look under the cowl
at the very last year's production of the P-210 (not the earlier airplanes).
  If you know what you are looking for,  you can spend an hour and still keep
seeing nice surprises at how well it was done.  If you don't know what you are
looking for,  you will just say "ho hum" and put the cowl back on in about 10
minutes.
 
 Somebody that did that one actually understood how to do that and why.
 
 I had to make a  dozen test flights during the baffle tweaking process on the
IV-P.   If I could start from scratch,  I could do a still better job on that
installation.
 
 But it takes lots of time and personal attention away from a lot of other
projects.
 
 We probably did not charge for more than half of the shop time and effort
that went into the one airplane.  Of course,  we could do it a second time in
half that time or less... but it still takes lots of time away from a lot of
other pressing projects.
 
 Regards,  George
