Several years ago I commented on this on the LML.  I noticed that the hoses
for the nose gear cylinder (LNC2) are looped at a QUITE small radius, which
seemed beyond a reasonable bend radius for the lancair supplied super stiff
hoses with user installed fittings.

I had www.aircrafthose.com  make up a set of teflon custom length hoses that
are very flexible and have a much smaller bend radius to replace all of my
hydraulic hoses.
