Hi guys,
There is available a VSI that is called an IVSI. It is very
sensitive and reacts right now. They are used in military helicopters
and I used them for years and trained many pilots for instrument flying.
I have one in my Europa and it works great. I'm sure it is cheeper than
a variometer for sail planes. Its a good option for thoes who want to
have it both ways.
