Electronic versus Pneumatic compensation in LX7000

My new LX7000 has instructions for setting up with electronic or
pneumatic compensation, but does not make a recommendation. My new
glider seems to have a very nice TE installation, so my bet is on the
pneumatic route, but if anyone has direct experience with this
instrument (or on the topic in general) I would appreciate any
feedback.

Oh, and same question on my Cambridge 302 ... I used electronic TE
compensation with it in my 304CZ, but I'm not sure that was the best
way to go. And if I connect both instruments to the same TE probe, how
much should they be separated in tube length?

Mike Borgelt recommends the Y junction to be installed well behind the pilot
seat.
I flew over 10 years ago with an LX 4000 and electronically compensated it
worked flawlessly.

Since neither uses a flask, you should be able to connect them together.
Without a flask to introduce airflow, they will not introduce pressure
errors, and pressure is what they sense. I'd put the tee close to the
instruments.

Ted, since you have the luxury of the option, why not try both and
compare? I would suggest hooking up your primary vario to the TE
probe, and setup the other to use electronic TE. After a few flights
you can decide to keep it that way which will let you still enjoy a TE
vario if your probe falls off inflight (or the tubing gets pinched,
etc..). If they don't match, you can go with the better of the two
methods.

BTW, I use electronic TE on a Westerboer VW911 for several years and
really liked it - no problems with yaw or gust sensitivity (on an LS4).

Hi Ted,
I like Kirks idea:
Please try both instruments in TE and electronic mode and tell us about your
findigs.
This will create an interesting post for many of us.
Thanks in advance

Would you please tell me the settings you have selected in the TE
setup page?

thanks!

I use 7 if I remember well. Will check next week end. Also I have
manifolded front and rear static.
