Dennis,
Mine is LS002.  i replace it when the canopy will not stay open. The 
design is a little poor and it takes a lot of force to hold the canopy 
due to the mechanical disadvantage that the struts enjoy. they are 
designed to have 100 lbs each as i remember.  the last two i bought and 
have not installed, are 130 lbs.  the heaviest that they make in that 
size i think.
how was your design changed?

      <div>Hi Bill,</div>
      <div> </div>
      <div>Do you measure the force of the canopy gas struts before
        replacing them?  Lancair can tell you the minimum rated force
        and pressing one down on a bathroom scale will tell you if it
        needs replacing.  What is your Legacy's serial number?  Mine is
        #257 and has the "heavy canopy" design, which is normal, due
        to Lancair changing the geometry to reduce firewall deflection
        with a closed canopy.  I haven't changed my canopy gas struts in
        the seven years I've been flying because they are still as
        charged as when new.</div>

        I have had a couple of instances where the wind blew the canopy
        down while I had my arm outside the cockpit.  The last time is
        the closest I have ever come to having a broken arm!  Damn that
        hurt!  Took weeks for the knot to go away on my forearm.<br>
        <br>
        We could use a better gas strut for this application.  I have
        already replaced them twice and have another pair ready to do it
        again.  They are especially bad in cold weather.<br>
