Lancair Legacy Design Flaw?
If it worked that way it would be a built-in safety factor helping to
forestall a stall of the main wing. But suppose the motor died and the
aircraft was then a glider. One must glide nose down. The horizontal
stabilizer forcing the nose down would then cause the pilot to pull back on
the stick to counteract the forces for aft. If the stabilizer stalled in
this attitude the nose is supposed to pitch down but would it? The tail
might just continue to drop provided the main wing still gets traction??? CG
is dependent upon both lifting both control surfaces as well as weight
distribution.

You seem to have the forces on the horizontal stabilizer backwards. The
force on the horizontal is down, (NOT up as with the main wing) which is
why an aircraft is stable in pitch unless improper loading places the CG
too far aft.
Of course, non of this applies to canard designs, which the Lancair is not.
