G'day Dan,
I have just had a Digiflight 200 fitted to my 3320.
I chose not to have the vertical speed function as I fly only VFR and
reckon after a lifetime of RPT IFR I have earned the right to ditch the
AP for climb and descent.
Only done two flight and I have to give the Digiflight thumbs up mate.
The calibration was easy on the first flight and that was done in
moderate turbulence with the AP holding ALT very well.
The next flight was a 2.5 hour X-country without dog legs but it worked
a treat and it locked into that GPS like it was on rails.
I like its simplicity. I had a problem choosing an AP initially. I
thought I would get the S-Tec but had a lack of panel space. I was
directed to the Tru Track Site by a bloke who has flown his RV around
the world three times, looked at my panel, and worked out it would fit
easily.
It's a ripper mate.
But as always, get another opinion.
Regards
DC
