How does one select an electric turn coordinator? The prices seem to vary by
50% or so for what look to the casual observer to be identical units. In my
VFR Europa this will be the only gyro.
EGC, IFR, RCA, Wultrad (ACS lowest price unit) ?? Surely, some are more
reliable than others, but how does one tell? Based on a discussion with a
maintenance tech, brush failure seems to be the most common failure followed
by bearings -- any other common problems? Do weight and size vary much?
Also read somewhere that there is a brushless unit which uses an AC motor
plus an internal inverter, but who makes it? Is it more reliable?
A friend suggests adding a switch to allow removing power from the TC during
severe clear weather. Is this reasonable, or will it likely be powered down
just when needed? Would this prolong its life or is airframe vibration the
failure inducer?
