Greetings flying folk,
I am seeking an economical AH, or turn coordinator system.
My needs are to provide some assistance when
VFR and the vis is poorly
or if when VFR on top the gaps are closing
or on top and the cloud tops are not horozontal.
.
Any suggestions on minimal systems greatly appreciated.
many thanks

How about a turn coordinator with a small venturi vacuum source?
