 Larry,
 
 Again, the wall is the red line (235-240 KIAS).  Also, High speed runs  at
 low altitudes on a hot day are testing the G-limit envelope.  Remember  that
if
 you bought a carbon Legacy kit and intended to race it at Reno, Lancair
 applied extra carbon in the tail cone and vertical stablizer area for
strength  and
 stiffness.  This need has shown up in stressed LNC2's as cracks in  the
 vertical stabilizer strake where is rises out of the tail cone.   Stressed
LNC2's
 are those that frequently (like always) fly in the yellow  arc regardless of,
 uh, conditions.
 
 It is possible to put a 390 in an LNC2 (one raced at Reno) and even turbo
 charge it.  Some care is required when operating at the edge of the design
 performance envelope.
 
 And, watch out for those runway incursions.
