I use a D10 in an ultralight (ATEC Zephyr) and have done for over 18 months. I find it very useful and readable except for the balance ball. The original ball was a black outline that was almost impossible to see. This has now changed to a full black ball which is better. However, would it be possbile to change the background on which the ball moves to white so that it shows up easily and can be read cross cockpit? This would more closely resemble the normal mechanical balance ball.
