Hi Bill,
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.

issues
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.
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.
