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).

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:

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 !
