Keith,
 
I don't know if its a good price but Dynon (
http://www.dynonavionics.com/docs/pitotfeatures.html
<http://www.dynonavionics.com/docs/pitotfeatures.html> ) has a $199 unit on
their site that also does angle of attach (apparently by measuring the
pressure differential between an angled opening and the pressure in the main
pitot) but that's only with their EFIS.  I didn't figure out if the pitot
works without their EFIS.  If it does, is $199 half way reasonable for a
heated pitot?
 
If I get any other feedback on the GRT unit from other than the Reflector,
I'll pass it along.
 
Chuck

Chuck,
 
I'm also looking for some "reports from the field" on the GRT EFIS.  I have
been checking their website pretty regularly the last few months, and they
note that 5 of their systems are now flying, so it's still pretty early.
They are shipping them as fast as they come off the line, so a lot more will
be flying by Oshkosh time.
 
Unless I hear some horror stories in the next few months, I'll probably be
putting a two-display GRT system in my panel along with their EIS 6000
engine monitor.  I'm thinking of a dedicated primary flight display for the
upper, and a multiple-mode display for the lower.  That would provide moving
map and graphical engine parameters on the lower display under normal
conditions, and a backup for the primary flight display if the upper one
ever goes belly-up.  The handheld and panel-mount GPSs would provide backup
moving map, and the EIS would provide digital engine parameters.  The other
backups would be a mechanical airspeed and altimeter, and the new turn
coordinator from TruTrak.  This looks to be a pretty fault-tolerant no-gyro
system at a very reasonable cost.  Any critics?
 
The only real shock lately has been the enormous recent price spike in pitot
tubes.  Anyone got a line on a reasonable-priced heated pitot?
 
Keith Hallsten, XLFG

With correct web-link and in non-annoying smaller print. 

Has anyone had some experience with Grand Rapids (
<http://www.grtavionics.com> http://www.grtavionics.com) new EFIS unit.  I
understand several have flow the GRT EIS system and think well of it and the
company, but of course, the jump to a full blow EFIS is a quantum leap.  On
GRT's web site, under installation, there was a photo of an installation in
Velocity N31VC, which, with Ronnie Brown's detective work, I understand
belonged to Rob at  <mailto:RJohn15183@aol.com> RJohn15183@aol.com, but I
haven't been able to contact him by email to see if the unit was installed
before he sold the plane or who's currently flying it....and what their
impressions were.

 
In short, anyone have any feedback about GRT's EFIS or know anyone I could
contact to discuss the same.
 
Chuck
