Anyone know what the cost of the AHRS really is? That seems to be the
main
thing. I can see how the rest could end up being cheaper easily.


Probably not that large actually. I believe it's based on accelerometers
derived from those used in the automotive industry. Look at those backup AIs
that run on PDAs- they cost around $1000.

There's a huge investment to make in the one-time cost of development and
certification. Enough that it probably has a pretty appreciable portion of
the cost of the first 5-10k units.
