Rob,
I used the extension sold by Avery tools, it worked well with a step drill installed.
The maximum diameter of the stepdrill was the one required to pull Vans
conduit trough.

To my knowledge Deems Davis and I are the only ones who have purchased OP.
Deems used the displays driven by Garmin 430/530 and SL 40. I have OP
integrated system with their Becker radios, air data computer, audio
panel,etc.
Contact me with any questions. I too am impressed with the system but their
deliveries too have suffered. Order early.

| Subject: | Instrument panel update- |
I'm going to provide some info regarding our recent update and learning
experience in converting our Glastar from a steam gauge based VFR
machine to an IFR capable glass panel machine. This experience has
been extremely valuable in preparation for the instrument panel I plan
to build for my RV-10.
Background. My dad and I built our Glastar and flew it May of '99,
instrumentation was essentially all second hand steam gauges, a KT76
transponder and a Garmin 250xl com/gps. We flew this until the summer
of 2006, at which time we began the planning for our new panel. The
goal was to make an IFR comfortable and safe plane.
Here's what went in: Garmin 530 nav,com,gps +GI-106A CDI/OBS,
Garmin 340 audio panel, Garmin 327
transponder,
Dynon D-100 EFIS
Here's what we re-used: Garmin 250 XL com-gps, Navaid single axis
autopilot
At this point everything is working very well, However, many items
took some digging to uncover and resolve the issues.
See photo attached of our new panel.
Lessons Learned:
1) Wet compass: We wanted the compass to be panel mounted, not up on
top of the glare shield, and in the old panel it worked fine. However,
in the new panel the compass did not work at all, no adjustments to the
compensation magnets would bring the compass in line. Ultimate
problem: residual magnetism in the spiral steel wire in the scat tube
that fed the eyeball vent right near the compass. Using a gauss-o-meter
I sniffed out the magnetism in the scat tube and ultimately changed the
scat tube to a type that uses a poly-plastic helic coil. (available from
McMaster-Carr). Now the compass works.
2) Navaid autopilot wouldn't listen to the Garmin 530, however it
worked fine with the Garmin 250xl: Solution: One of the RS-232
settings that is selectable in the Garmin 530 is called "aviation data
format-no altitude" this is the one that the Navaid autopilot needs, it
cannot accept aviation data with altitude.
3) Limitation of the Garmin 530's RS-232 selectable ports: ONLY one
may be set up in the aviation data format. If you have multiple
devices which need this format you may have a problem. I ran into
this with the Dynon and the Navaid autopilot, since both need aviation
data format and the Navaid device cannot accept the data with altitude
in it, I cannot see the GPS reported altitude on the Dynon's HSI
screen. (minor detail, but annoying)
4) The Dynon's new HSI split screen software update. Awesome
for en route procedures but the thickness of the CDI line presented on
the HSI is just too fat to shoot a really nice ILS approach. I know
the GPS mode is for reference only and I'm going to get flamed for this,
but I'm just observing that the representation on the glass panel is not
as good as the analog CDI needle.
5) Antenna cable connections: The new antennas we added for the
panel update all had Mil spec crimp-on BNC style connectors, assemble
with the real crimp tooling, However, two of the old antennas, (com1
and transponder) had aftermarket style push on BNC connectors. (which
worked fine for 7 years) Well after all the shuffling around under the
instrument panel the shield termination on com1 became intermittent and
we had corresponding intermittent problems communicating on our fancy
new Garmin 530. Changed all connectors, problem resolved.
6) Static system leaks: passing the static system check was a
royal pain, our second hand steam gauge airspeed indicator had a static
leak around the temperature compensation knob. Tracking down static
leaks is a slow process!
7) Transponder: I always had trouble entering transponder codes
into our old KT76, I couldn't turn the knobs fast enough to keep up
with ATC. Well, if you haven't had the pleasure of a transponder
like the Garmin 327, it is huge, huge improvement. The direct entry of
numbers into the keypad let's me enter the numbers as ATC gives them to
me, awesome!
8) Tied for #1 favorite thing on the new panel: The wind arrow and
the track triangle on the HSI. Wow, these two things dramatically
improved how I handle the plane.
More later.
-Bob

I can't use flashing LED because I am using the LED in the switch itself and
thus need to use the one designed for the switch. Thanks for the thought.
I have found a good soul to assist me so I think we have this issue licked.

You are right on the auto flasher. It requires the greater
load of standard bulbs to heat the bimetal strip on the
mechanical types. Try this link for one source of flashing
leds -

If you can replace your current led you could substitute a

I just mounted an OAT probe during my RV8 panel remodel. Since I had to
mount the magnetometer in the wingtip, and the OAT probe hooks up to
that, I mounted the probe in the aft part of the tip, where it is shaded
by the white wing tip, but is still exposed to the airflow. It's mounted
thru the outboard rib, with the probe portion extending outboard into
the void between the rib, and the tip rib. If you look forward into the
gap between the aileron and tip you can see it, but it's shaded, and the
air moves in that area. Works great.

| Subject: | Re: Instrument Calibration |
OAT readings are affected by whether the air is compressed. Compressed
air heats up. Now, air in an engine inlet duct will compress somewhat
compared to the free-stream (also depends on the suction of the
engine) but shouldn't be compressed that much to severely impact the
accuracy of a probe reading. Different placements on the exterior of
an aircraft may affect the reading too. Some areas that have higher or
lower pressures will increase or decrease the temperature but again to
only a slight degree at the speeds we're talking about. Best place to
me is anywhere on the airplane not close to a heat source (i.e. in the
engine compartment or aft of the cooling air outlet.). My old Grumman
had the OAT probe in the windshield. Somewhere on top of the airplane
(or maybe the vertical tail leading edge) would be my optimum choice.

Gary, just curious, if you do this without a low voltage sense circuit that
is killed when the master is off, how are you planning on de-activating the
"reminder" flasher with the master off. I am guessing with a relay that
kills the flasher when the master is on but if it flashes with the master
off, how will you turn it off for real?
The option with the LV warning is 1) off with the engine running because the
voltage is up (charging) and 2) blinks when the master is on, engine off,
but sensing only battery voltage, then off with the master? How do you
accomplish all that with just a flasher relay?
Just another thought which is much cheaper than the B&C Reg with LV might be
to wire a low oil pressure switch in to the main buss so that it flashes
when the master is on but engine off and then off when running. It's each
to add to the third manifold port where the OP and FP sensors go. $32 from
B&C
This link shows it wired through a Hobbs meter and a buzzer but you could
just drop the meter and buzzer and substitute your flashing LED. BTW, you
can get a "flashing" LED with resistor from Radio Shack in four colors for
about $3.

In case anyone is interested, OP says lead time right now on the standard
systems is 4-5 weeks, and 6 weeks on the integrated. I'm not sure if that
is accurate or not, but that is what the vendor is saying.

Or, you could just leave your strobes or flashing beacon on all the
time. One glance back at the airplane (if it's tied down) before you
drive away will catch the master on. If you have a hangar, the beacon
or strobes will be noticeable, even in daylight!
