 I am one of the many Chelton and Trutrak customers who have been waiting for
the ellusive Pinpont GADAHRS
 http://www.direct2avionics.com/pdfs/D2A_release_2.20.pdf  and Trutrak  2 1/4"
ADI http://www.trutrakflightsystems.com/ttfsinstruments.html to arrive. (My
Chelton was not shipped with the Crossboxw ADHRS). As a possible alternative
to the Trutrak ADI I was considering the EGYRO2 ELECTRIC HORIZON
 http://www.pcflightsystems.com/EGYRO2.htm
 or the MGL ARTIFICIAL HORIZON
 http://www.mglavionics.co.za/singles.html
 
 My panel has already been cut and complete except for these items so I am
limited to a 2 1/4" receptacle.
 
 While the 2 1/4" Trutrak ADI with self-contained battery was initially
planned as a b/u AI, without the Chelton Sport EFIS functioning I would need
some primary AI to fly safely. Attached is a pdf file of my panel [not!]  I would
greatly appreciate feedback from the LML on the advisibility of using either
of these AI alternatives and whether or not one could depend on them for IFR
flight (disclaimers by the manufacturers notwithstanding)  given the
configuration of the rest of the panel which includes a Garmin 480.

[The PDF of Dr. Neustein's panel is too large to send with the regular LML
distribution.  I've uploaded it to the LML website, you can find it at the
