Flight recorder that records attitude

Hello,

I created a flight data recorder during my dissertation - and am
considering the feasibility of turning this into a usable product. The
unique feature of my device is that in addition to the usual
parameters - it also records attitude information (roll, pitch, yaw)
and does so in an aerobatic environment. The software can then
graphically replay the flight. I feel this could be very useful for
practising aerobatic manoeuvres, for use in training or for attaining
records (record verification). Or perhaps as a value add DVD for red-
letter day type trial lessons.

Does the community feel that such a product would add value and be of
use? Would you be interested in such a recorder? I'm very keen to hear
your views.

Thanks,

Andrew Murray
