Default Mech vario - Static vs TE?

I use to have a Borgelt B-50 in my HP-14. It was installed as prescribed in
the B-50 manual.
http://www.borgeltinstruments.com/B50man.pdf

" The T-piece in the T.E. line should be as close as possible to the T.E.
probe although in practice it has been found that if the T.E.
line is split under the pilot's seat, further aft behind the seat or near
the trailing edge of the wing no problems will result."

With the turtle-back off the '14 it was easy to put the T-piece in the
tail-cone aft of the trailing edge of the wing.

I would recommend splitting the TE line as far back from the
instrument as possible (6 feet is probably plenty, but more doesn't
hurt) to avoid interference. Otherwise the varios seem to "play" with
each other and you get pretty bad compensation.

Quick question -- for a mechanical vario (such as Winter), do most
people hook up the static port to the TE probe, or the static line? It
seems the TE probe would naturally compensate the vario for stick
movements, but is there a disadvantage? -- dbrunone


Connect to total energy probe.
If used with a non flow type electric variometer, connect in parallel and
with at least 6 feet of tubing from where the TE lines from the vario join
to the TE source line.
