>ps Ever had a compass fracture in flight and dump the oil over you. I had
that happen to me yesterday - it's smelly horrible stuff!!

I have had it happen in a Jodel when it was my only compass flying VFR in
1500m visibility - not to be recommended!!
As a result I am not intending to use a traditional liquid filled compass
in my Europa. Unless you are in very smooth conditions flying straight and
level they never seem to be very easy to read. They also have a parallax
error unless they are mounted right in front of you. My fit is as follows:
Primary heading instrument - Electric DI manually updated by either compass
below.
Secondary heading instrument - Fluxgate compass as part of the RMI
uEncoder package.
Backup heading instrument - Digital fluxgate compass powered off the
aircraft system with internal battery (2 x AA) backup.
Although all 3 of these use electricity it is extremely unlikely that I
will get a situation where none of them are working.
