The L2....

If your glider has fiberglass tail boon (no carbon fiber) this
is a great solution....

We installed about 10 or 12 of these in gliders with no problems at all...

If you install an L2, MAKE SURE IT IS INSTALLED VERTICALLY !
"Works Great!" said the mechanic who glassed in some of these
horizontally. Don't do that!
