As promised, today I took measurements on my LNC2 ailerons that are rigged "a 
bit high".

With the stick at neutral and at rest, each outboard trailing edge of the 
aileron is .1 inch higher than the adjacent wingtip trailing edge.

If I clamp down one aileron at the outboard trailing to the wingtip, the 
other aileron can be gently pushed thru the range of .08" high to .26" high 
for a lash dead band of .18".  Note that the .1" high on each seems to put 
enough air load on the system to take care of the lash.

Measure your own and report back!  (This is addressed to all Lancair flyers)

This is important to my system since the trim system is servo-driven 
spring-loaded.  I.e. No trim tab.  A trimmed tab may provide some airplanes, 
at cruise, with enough load to eliminate "buzz".  Those who report that their 
plane always flies straight and true (regardless of lateral load) may be so 
perfect that the aileron "neutral" position is subject to disturbances in the 
lash dead band.
