Be very judicious in the use of the fan.
I had been using the procedure outlined by Jim Schulman on home-barista.com.
In this procedure he suggests using max heat and max fan for ramp to 1st(3
to 4 minutes).  I found that if I use max fan for any length of time over 1
minute that too much moisture is extracted from the beans and I loose almost
all sugar development.  The coffee comes out very flat with a hard edge to
it.  This happened for me whether I used max heat/max fan on the ramp to 1st
or a reduced heat/max fan on ramp to first.
I cut back the fan to 4.5 for almost all of the roast (excepting minor
adjustments for a short time to control max ET and very small increases in
the finish to control finish time) and ended up with much better results,
the sweetness and aromatics are back and the coffee tastes much as I would
expect.
I have also shortened up my finish just a tad to retain more volatile
aromatics.  I still have much to learn a lot more experimentation, but I
think I am at least on the right track now.
The very low humidity (winter) that I am roasting in may also be playing a
role here.
This may not be news to the experienced roasters on the list, but it took me
a very long time to figure this one out.  The thread on Facebook about
baked/overdeveloped coffee referenced by Tom last week put me on to the
possible solution to my vexing problem.

Interesting observation. On the flip side: I find that when doing
back-to-back roasts I *will* have a chaff fire if I have the fan below 4.5.
So, I typically keep the fan to 4.5 until the onset of first and then crank
the fan up all the way for the finish.

I haven't experimented much with Fan settings on the finish, it may not be
as important in that phase and I do increase the fan a bit on finish, up to
6 or 7 for a short time, but during ramp to 1st max fan definitely does not
work for me.  The idea behind using max fan was to put heat into the beans
fast to get through the ramp, unfortunately it also dried the beans out to
much producing an overdeveloped hard flavor with no sweetness.
I now have a base that produces acceptable (very good!) roasts and i will
experiment from there.

I don't think it is possible to get to 1C in 3-4 minute and can't imagine wanting to if I could.   Much too fast in my opinion.  I shoot for 9 min to 1C and another 4-5 minutes to finish.
If I see the heat close to stalling during 1C I will often turn the fan on a higher setting for a few seconds to pull some heat from ET.  
I have also leaned that the Quest is more stable if a slow warm up is used.  I have had two very slow first roasts and yesterday I preheated slowly and the first roast was normal.  I am
sure the ambient temp affected the roasts.
On another subject I would like to hear how others are cleaning their Quest.  I broke my down after 10 roasts out of curiosity and cleaned it with Alcohol and Windex.  There was a heavy
collection of oils in the drying area and around the fan.  There was hardly anything on the drum.  I dropped the chaff basket in some hot carfiza solution and it cleaned it like new in a couple
of minutes.  It would be nice to drop the drum in carfiza solution when it gets more oils on it. 
Love the quality of construction and the way it contains the chaff.

Yikes....a chaff fire?
The first thing that I do when the beans are dumped from the drum into the basket is open the drying chamber door and vacuum out the chaff.  
Yesterday there was a wasp flying around and I sucked it into the vacuum as well!  :)
I have never witnessed anything close to a fire.  I don't think I have ever had the fan lower than 4.

Thank you very much, Ricky!
 
Your observations are very helpful!
 
I'm still feeling awkward about joining Facebook for coffee-information, but your post is seriously useful!
 
Is anyone willing to forward these Facebook posts to those of us on the outside?
 
Happy Roasting,
