Hi Guys,
I just came back from a week of XC flying all over the Southern US.
One of my stops was a visit at Don Rivera's Airflow Performance World
Headquarters in Spartanburg, SC.
He and one of his technicians (Kyle, if I remember correctly) spent one
whole day to tweak my setup.
We got the cylinders to peak within 0.2 of a Gallon FF and bumped the fuel
pressure up to provide a more generous supply of the Blue Stuff.
After everything was said and done I left with a wonderfully smooth running
engine and due to my reset fuel pressure (36 gph on T/O) even more thrilling
T/O performance than I had before.
Dons outfit is immaculate, everybody I met was extremely helpful and working
with them was a real pleasure.
I can highly recommend his products and his operation.
Cheers
Wolfgang

Hi Guys,
I am getting sick and tired of my TruTrak AP performance.
Yesterday I flew a fairly long leg of about 2.75 hrs and the altitude
functions of my AP (Sorcerer) simply stopped providing any services after
about 2 hrs. of flight time.
All this was preceded (not to speak of the 6 month I am trying to get this
AP to work) by 2 hrs. of yo-yoing around at altitudes of 6500' to 12500' .
>From the beginning of my trip the VNAV functions were unreliable, level offs
were shaky, enroute descents (10000ft in 30 NM) impossible and roll steering
so-so.
Nothing about the performance of this machine appears to be predictable.
The only thing which is reliable is that it will stop performing after a
while.
What a deal for $10000.00.
I can't put my finger on one specific problem. In my case it's a multitude
of problems and after half a year of fishing in the dark I simply want it
fixed.
I talked to many pilots in the last month and none of them (with the
exception of some RV guys) had a fully functioning TruTrak AP.
Please let's get together and form a solid front to get this fixed.
I talked to F1 Boss yesterday and he signaled support.
Please publish your experience on this forum.
Cheers
Wolfgang

Hey Wolfgang,
Sorry to hear about your AP Troubles. What did TruTrak have to say
about your complaints to the malfunctioning of their unit(s)? Curious
to find out what their position is...

TruTrak AP won't work....must be a Rocket thing??!!! Seriously, I take
it you've talked to TruTrak and have sent the unit in for checkout?
TruTrak is pretty diligent about customer support and there are a LOT of
perfectly satisfied users, myself included, though with a TruTrak VGSV
(or whatever) in a Velocity. After a couple months of original
installation, it would wonder R/L at its pleasure. TT fixed it (an
electronic gyro issue) by sending a new unit Next Day with the
understanding that I would send my unit back when I got it removed from
the plane--pretty trusting, I would say. Since then, it locks on
altitude and lateral path like a bulldog and doesn't let go. Sound like
your unit needs a little fixin' or, if the data stream is coming from an
outside source, that that should be checked also.
I have absolutely no first hand familiarity with the Magician, errrr
Sorcerer, but I, and most people I know, give TT the benefit of the
doubt when it comes to AP design and service.

Hi Wolfgang,
I'm sure you've already checked the obvious (static source, wiring)? Will
yours hold altitude once set?
I'm running the TruTrak with altitude hold, and GPSS coupled to a CNX80 (480
now). After initially tuning as per the manual, I just love my autopilot.
To make it work right, I did have to do some tuning, but the manual worked
good here. I don't fly heading too much, but in the beginning, it would
loose heading every now and then, but I think it was more because I was
doing heavy banking just before I activated it. If I do a roll, and don't
wait at least one minute, the AP is very confused.
Regards,
Jeff

Subject: | Exhaust BPA interference |
Hi all,
Today I finally got around to installing my cold air induction and inverted
system. Of course I left the exhaust to last. I have been running a
Vettermann system, love it and people tell me it sounds great on the ground.
Problem is that it interferes with the BPA cold air induction piping.
Does anyone out there have the BPA system? If so what exhaust are you
running and where can I get my hands on one?
Regards,
Jeff

John Forsling makes tuned exhaust for BPE Cold air. He is recommended by
Allen Barrett. John actually spent time in BPE's shop and built several
exhausts and ran them on BPE's dyno to see what worked and what didn't.
John used to work work Vetterman before going off on his own. He's not
an e-mail/computer guy. e-mail me off line for his phone number. I have
his exhaust but have not installed it yet. It's ceramic coated inside
and out and priced competitively.

John Forsling (Parker, CO) has Tuned Exhaust which is often ceramic
coated, specifically routed for the Barrett Cold Air System and the
Lycoming IO-540.
