Wolfgang,
 
It is not disturbing.  Lancairs demand respect.  High performance sometimes requires a tradeoff in low speed controlability.  Every amateur built has different flight characteristics (actually spam cans may differ somewhat also).  High performance jets don't require stall training either. 
 
Stalls should be avoided because slick airplanes speed response is very quick.  These airplanes generally don't stall in cruise - only in the slow flight regime around the stinking airport.  Why drag these in during approach and close to stall when turbulence, microbursts or sudden wind shifts (shear) leave you in the lurch.  If it goes wrong, it goes wrong very fast.  It is the uninformed pilot that can lose control because of slow speed maneuvering that has led the way to distressing accident stats.
 
It is always interesting to look at the speed range of standard aircraft.  Most span cans have a minimal range.  Lancairs and their ilk have a rather broad range (max cruise to landing) and, as such, require compromises.  I like to fly at max speeds and am willing to respect the limitations at lower speeds.  This ain't no Cub (or LSA).

Is it just me or does anyone else find it just a bit disturbing that the Lancairs have such "fearsome" stall characteristics ?

Bruce,
 
Au contraire, mon ami......
 
The Advanced Systems AOA does not require stalling the aircraft.  Read for theory and calibration:

Every single AOA I know of requires you to stall the aircraft to calibrate the AOA.

One of the main reasons all of us IV-P owners have a hell of a time getting insurance for our airplanes is because too many guys "explored" the stall characteristics of their airplane (and for many it was their last flight).   I fly another airplane that can fly comfortably at 60 degrees AOA, and have a good bit of time as an operational test pilot, but I will never stall my IV-P intentionally.  Or even get close.  Like Colyn and John, I'm 120 on downwind, 110 at the base turn and 100 on final until the runway is assured.   Unless we fly the pattern at 8000 feet AGL, a stall will probably be fatal for any of us.  Please don't be the next one to prove this point !
