I presume you mean that your DG and AI are vacuum driven. Virtually all
TC'c are electric.

We have a backup electric AI in our Arrow, and it works very well. To
extend its life, we have an on/off switch for it, and only turn it on when
in IMC. It is mounted in an otherwise unused space on the right side of the
radio stack. But many owners are ditching their ADFs these days, and the
hole where the ADF head was makes a good home for an electric AI.


Since TC's are no longer required you can mount the elctric AI right
next to the vacuum AI.
