For the past 6 years I've been using an SN10, backed up with a (no
flask) Westerboer electric (with audio), running on two seperate
battery systems, either of which can run some or all of the panel. No
mechanical - traded in the Winter the glider came with for the
Westerboer.

Both varios match perfectly, which makes sense since they are plumbed
to the same TE probe. The only improvement I would like would be to
have one vario use electronic TE (selectable, ideally) and the other
the probe, for redundancy in case the probe failed (yes that has
happened to me, with both an earlier glider/probe combo and in the TE
plumbing in the current glider).

Personally, I would prefer to have big digital airspeed, altitude, and
angle of attack displays (with some form of analog trend information)
in place of the sticky and slow mechanical airspeed indicator and
altimeter. Without electrics, I'm going to land anyway, so I design my
electrics accordingly. And I know (from experience) that I can fly
500k+ without a working airspeed indicator. I also care more about GPS
elevation and height above ground than what the pneumatic altimeter is
lying about.

Caveat - I wouldn't even think about setting up a 1-26 or a primary
trainer this way! This is for serious XC and racing fanatics....be
sure not to tell the spousal unit of the cost involved!
