Per Jim's recommendation I also used the SE-200 tubing. For those in the US it
is sold by McMaster Carr as "Ultra-Chemical-Resistant Versilon PVC Tubing 1/4
ID, 3/8 OD" PN 6519T13. The stuff is great and after 3 years it has not stained
and remains crystal clear making reading the fuel level very easy.
However, I installed my tube right against the cockpit module's seat back in the
center (if someone has seen Bud Yerly's airplane, but without the fancy base).
That means I did not have to bend this tube to place it in the foot well as
the plans indicate. I have 1/4" aluminum tubing from the tank and vent and bent
90s at the top and bottom of the seat back center. From there a straight run
of the SE-200 against the seat back. No bends.
Jim is right, the stuff doesn't like bends because the FEP liner inside will collapse.
But in a near straight line it is amazing for fuel sight gage use. Also,
pushing the tube into the 1/4" tubing is hard because the liner separates and
bunches up in front of the tubing. But with some patience it is doable. Certainly
worth the effort.
But I don't know if you can change the location of the fuel sight gage in England.
Could you use barbed fittings and use the SE-200 only on the vertical run
where you read the fuel level?
Honestly, I have no clue why Europa didn't place it against the seat back. Easy
to see and fairly accurate.

| Subject: | Dynon HDX Autopilot Settings |
Hi folks,
I'm back in the air after determining my no generator issues were due to
a poor connection.
When I first installed the Dynon Autopilot on my HDX system, it worked
right out of the box using the default settings in terms of
sensitivities, gains, etc. for both roll and pitch.
A software upgrade introduced a tendency for an aggressive roll tendency
when initiating a turn. Others on the Dynon forum had the same issues.
Then another software update provided 'the fix' but it was also clear
that for me the default settings no longer worked in the pitch axis.
I have gone through the process for adjusting the settings as provided
by the autopilot tuning manual but it still 'wanders' having captured
altitude quite nicely.
I'm thinking of asking Dynon how to reinstall previous software versions
but then I thought I would ask anyone who has a Dynon HDX system with an
autopilot who is running the current software if they could send me
their settings.
Any pointers would be appreciated.
Regards,
Martin Tuck
