For vfr pilot with no training I would install simple electronic AH
(Dynon, Gemini etc.) for the purpose of keeping your glider right
side up and getting out of imc safely. You can fly whole day with T&B
only,
but it requires some training.

I think the same definitely applies to the Dynon electronic AH and its
relations: you still need the training before trying to use it 'for
real'.

I've had some training with a Dynon (bucket over my head in an SF-25)
and find that I prefer using a partial panel, mainly because the Dynon
heading indicator is just a small box showing the heading in degrees: I
don't find it nearly as easy to scan as an analogue indicator or a
ribbon like some of the other electronic AHs provide.

Its just as well I prefer the partial panel because that is what is in
my glider and there is no space in the panel to add an AH.

Martin, I am confused. What instruments do you have in your 'partial
panel' which you prefer to an electronic A-H? Surely you are not saying
that you find it easier to cloud fly using a turn and slip than using an
A-H?

Yes, exactly that: I don't see all that much difference between a T&S+ASI
and an AH for flying straight or maintaining a constant rate 1 turn in
cloud.

Are you referring to straightening up in the right direction when
you have finished thermalling,

Yes. When it comes to straightening out or flying on a heading I find
that a lot easier with a 'proper' compass or LK8000's moving map than I
do trying to use the tiny 3 digit bearing box on the Dynon AH. For me
anyway this is a clear case of 'analogue display trumps digital'.

in which case surely you would level the
wings using the A-H and use your gps or your compass to exit your cloud
in the right direction?

As I'm never far from home without a task set in LK8000, it will always
be showing the leg I need to resume travel along and I reckon that
straightening out along that is at least as easy as using an analogue
compass even after allowing for the map updating lag when turning.

A personal view, of course: ymmv.
