The Lancair aircraft are intolerant of pilot inattention in slow flight and
particularily during stalls.  I stress to all pilots that I check out that
the one thing that will cause them bodily harm is cross controlling the
aircraft at low speeds (stalls).  The most important items in stall testing
in these aircraft are to proceed with caution, start with power COMPLETELY
OFF and KEEP THE BALL IN THE MIDDLE.  Once you have mastered this, then
proceed with testing with partial power before trying them with massive
amounts of TORQUE.   Remember that we are flying a wing dthat is not designed
for slow speed characteristics like the old Clark Y airfoil in early training
aricraft.

Tis extremely difficult to remind oneself that their primary objective was to
drain the swamp, when they are up to their ass in alligators...  Get good
training, then get LOTS of altitude before attempting stalls in your Lancair.
  For most of my experiences they fall off straight ahead with power off, and
do a bit of torque roll with power on.  All bets are off on Iv's with
winglets, they are a special breed unto themselves, and any mis-alignment
will cause unknown results.  One I tested at great length demonstrated flow
reversal just before the break which was predictable after a few tries.  It
always broke nose down and to the right, every time, but always with the ball
in the middle.

I took one of the Flight Craft instructors up with me in 409L after they
complained that the airplane would "always" go inverted in a power off stall,
we went up and I repeatedly had the airplane stall (very docile and
predictable) staight ahead every time, wings level, ball in the middle.  I
could stall 409L and hold the stick fully aft in a fully developed stall and
it did not demonstrate any tendancy to roll over on its back and play turtle.
  But, I kept the ball in the MIDDLE...

Remember PLEASE, you are flying a high performance wing, not unlike some of
the business jets out there, and they do not go out and stall them.....

Fly SMART and SAFE..

Mike
