People should not be made to wait for a product essential to the
functioning of a system on which their lives will depend without knowing
anything about the product, who designed it, who makes it, how it has
been tested and how it has performed both in testing and in the field.  
========================================================================
=====  

I had installed a 3-screen Chelton Sport with the Crosbow 425 AHRS.  It
was a rather entertaining combination to watch as it spun faster than
Patty Wagsstaff at her best.  The folks at D2 were always approachable
during the search for a solution which in the end became the Pinpoint
GADAHRS.  I prewired for that unit as D2 did their early testing, and I
installed it as soon as I had it in my hot little hands.  There were a
few software mods and one hardware change as the system evolved from
good to really great.  All that time D2 kept in touch either informing
me about their changes or asking about my experiences.  They sent out
written questionaires and they followed up with phone calls until days
before they closed their doors.  

At this point I have a system that works well mechanically and my only
concern is about software updates. I still need to set the
compressibility but other than that we are good for flight.  The
features built into the Pinpoint hardware makes it more capable that the
Crossbow would have been, had they ever been able to make it work
reliably.  

The Chelton Sport is not TSO'd and therefore should not be used for life
support - only as a sophisticated backup.  Most of us will use it as the
main source of info while flying but will hopefully cross check with the
steam gauges to ensure we are not being led down an erroneous flight
path.  

All we need now is for Chelton to carry on the cooperative efforts with
Pinpoint that were initiated by D2, and we'll all be happy campers - er,
flyers.  Based on the Chelton history and reputation I cannot expect
anything less.
