Our club is considering installing an electric AI as a backup after a
vacuum gyro failure not involving the suction system. We have three
cherokees and are looking at three alternatives (we'd like the same one
in all the aircraft):

The first is a $4000 unit, the other two are less than half that.
Anybody out there have any experience with these units, or the companies
that make them?

I know nothing about gyros, but don't assumme that the more expensive
one is necessarily better. It could even be worse. You can't tell
anythng from the price. Inferior goods are often priced very high, to
convey to naive consumers the notion it is better.

Have you checked Aviation Consumer?

We've had the last one you linked
(http://www.gyrohouse.com/catalog/items/item551.html
) in a club 182. It's got about 850hrs on it so far with no problems at
all. Although we haven't needed to use it in a vacum failure yet it
makes me feel fantastic in the clouds to "see double".

Also I had an alternator failure when IMC once and the little red flag
that popped out on this AI was what made me first notice the failure
(this 182 has no low voltage light- just an ammeter).

The other nice thing about out installation is that the second AI is in
the ol VOR 1 hole, which puts it just two holes away from the primary
AI. I think having the backup as plainly visible as possible is
important if it's backing up the vacum AI.

There were some posts a couple of years ago about short lifespans on
the RC Allen units. The Midcontinent unit has a slower rotational
speed and longer expected life.

I haven't heard anything yet about the one from Sporty's.

I'd make the decision based on how long you expect to run the airplane.
