If it's a turn and bank indicator, it's like a level. A curved upwards class with a bubble in it. There are no electrics to it. It just sits there and tells you if you are in a co-ordinated turn, or not. I doubt if this instrument would give you any useful information. You wouldn't want to put a car in the "attitude" this instrument measures.
Basically, if you turn the yoke, or move the stick sideways, the bubble moves down the glass off center, telling you the wings are no longer level, but you are still not in a turn. To make the plane turn, you must pull back the yoke/stick to "climb" up the turn, not gaining altitude. The tail is now "slipping" outwards, so you must put in some rudder and the bubble gets centered at the bottom between two lines. This is referred to as a Co-ordinted turn, meaning everything is centered in the turn. You no longer feel like your being pushed across the seat. If you had your eyes closed, in a standard turn you would feel no turn at all.
What you may be after is something to give you G's, force of the turn.
