Thanks for the responses and ideas Darryl and Bill. *I spent yesterday
afternoon with the glider. *Following your suggestions Darryl I
started leak checking the total energy line first. *After taking the
TE lines off the 2 varios I confirmed that indeed there was a massive
leak in the line somewhere. *It would not hold pressure or suction for
even a second. *I took the seat pan out and tracked the leak back to
the last possible bit of tubing before it disappears into the bulkhead
of the landing gear. *It seems that in my enthusiasm to get the ship
ready when I first purchased it 6 years ago I was cutting into the
plastic covering that surrounds all the tubes and sliced my total
energy line up pretty good. *Duh!!! *That would explain why I never
experienced total energy in this glider. *It was basically a static
line connected to the varios. *A quick cut of the tubing and a single
splice later with a foot of new tubing and the line holds both air and
suction very well. *No leaks whatever now. *Yeah! *Don't have to cut
into the tail like it was starting to look likely would happen. *I am
really looking forward to flight testing the glider this next week.
Thanks again for the suggestions and helpful ideas.

The biggest problem solved. *Now, anyone ever experience the Cambridge
LNAV problem I mentioned in the first post? *It is reading about 4" of
millibars too low for the real pressure at a known altitude. *Right
now that just means that I have another 400 feet for safely getting
home if I rely on the instrument. *Not the end of the world but would
be nice to fix since I use this logger for my contest files.

Thanks again!

You mention using the "logger" for your contest files. The altimeter
in the LNAV is not used for the flight log in the GPS (Model 20 or
whatever you have attached). Those GPS devices have their own pressure
altimeters (they have to to avoid possible tampering).
