There was a time when I entered MS71 and it wouldn't chart the route because
MS71 wasn't in the database. There have been some updates and now it works.

Larry, sorry you are having troubles with the Dynon.
While we can't possibly know what the failure rate for this system (or any
other new EFIS) is yet, we must be humble to how difficult it is to design a
device of this complexity with minimal failure potentials.
I'm sure this will bring on the torches, but we seem to be in a period right
now where there are more problems with the new EFIS systems than with the
ancient mechanical systems they are replacing. This will change, of course,
but be aware that this is often the nature of new technology. There are no
free lunches.

Sam,
That is true as far as airspeed and altitude, that I don't normally use on
the Dynon and usually have turned off. The attitude indicator problem is
pretty much like the failure you would get with a failed vacuum system.
There is an indication that is slowly changing, sometimes near correct and
sometimes way wrong.

Nope. You may be thinking of the GPS rollover a few years ago that some

Alex,
Everyone can agree that all of the EFIS have had some teething issues,
some more than others. But if we consider all the instruments and
systems a single EFIS/EIS replaces, or never were even available before,
it would seem that the 'inop rate' is actually very low, especially for
a sophisticated, complex instrument right out of the gate. If we
tallied all the problems that we would have with the old individual
instruments, I'm guessing the total would be significantly greater than
what is seen with these new electronic systems. It gets noticed more
when all the malfunctions that could possibly happen show up in one
instruments...it may seem like a lot but doubt that it really is.
Heck, the eInstruments for GA have only had 2-3 real years to sort
things out. The aircraft industry has been perfecting the vacuum pump
and instruments for decades and they still crap out with frustrating
regularity, so I think we're making progress.

I just passed my transponder check which used my D10 as the encoder. The tester
hooked up to the static input and reduced the pressure up to 15,000 feet. The
D10, which deduces airspeed from pitot to static pressure difference, had me
going 585 mph by the time I was up to 15,000. Shoot! I wanted to break Mach
1. But the tester dude was impressed that the Dynon didn't stop at a limit
like a regular airspeed would. It was also interesting to see that the software
does indeed use pressure differences in it's algorithms for attitude determination.
On the way up to altitude, the horizon showed a descending left turn
as I recall. On the way back down, a climbing left turn. Nuts. Now I can't
remember but it might have been climbing & then descending. Anyway, it all smoothed
out once the test static pressure returned to ambient.

Pat;
Does your engine have a Vernatherm valve in the oil system ? If so it
may
be sticking in the open position; this allows the oil to circulate
through the
cooler all the time. The Vernatherm valve allows oil through the
cooler
only when the temperature reaches a certain point.
You can remove the Vernatherm valve and submerse it in a can of
automatic
transmission fluid , heated with a propane torch. You can put a candy
thermometer in the can to keep track of the temperature up to 400 - 500
degrees. BE
CAREFUL !! That is HOT !!
You can see if the valve moves and what temperature it reaches when it
moves.

Made the marks with a small file.
A ring all the way around every 5 gallons and a slash for each gallon.
The first mark is 4 gallons.

This GPS is supposed to run 4 hours on the battery in case of a power

I ordered a new battery online from Garmin. $60.00
Hope this solves my problem but if not it still needed the battery.

I am not familiar with your model of GPS, so I hope that is the battery
you need. The battery I had to repalce was
an internal battery that keeps all of the GPS information in memory. It
is sort of like the internal battery in your computer
that keeps information in your computer when it is not in use.

Mickey,
What grade of stainless are you cutting? 303 is
easily machinable where 304 is near impossible to
machine unless you use expensive carbide cutters and a
lot of them. Ask me how I know. 303 can be cut with
high speed tooling but I prefer carbide as it will
usually stay sharp to finish the job. A machine shop
will charge you $50 or more to set up the job and then
the time to actually do the machining. And only when
they have extra time to do it. Ask me how I know. I
have a lathe and a mill in my basement so now I make
my own parts when I can.

As far as the pitch attitude goes, the Dynon uses airspeed info to
compensate for acceleration errors. If the aircraft accelerates, the
pitch attitude algorithm would incorrectly sense an attitude change.
You can see this with a normal mechanical attitude indicator if you
can accelerate quickly enough - it will show a false pitch attitude
change. The Dynon EFIS looks at the airspeed changing, sees that you
must be accelerating, so it adjusts the calculated pitch attitude to
compensate for the error due to the acceleration. This is reported
to work very well when the aircraft is flying. But, if you hook up
the pitot-static system to a test set, so you can change the sensed
airspeed on the ground, the EFIS is fooled. The displayed attitude
will correct itself once the airspeed stabilizes at a constant value.
As far as the bank goes, I'm not sure what would be going on there.

Ouch. I don't really know what grade of stainless
steel it is - I picked up a bunch of scrap SS
from a junkyard for 3 dollars.
I checked into the greenlee punches, and they look
like they would work great, but they are rather
expensive.
I'm going to see how much the machine shop charges,
and possibly try to find some thinner material.
Thanks, guys, for all the hints.

A foot of Tygon is easy to obtain, probably free if you ask a friend, &
unbreakable. Mark it with a soldering iron or wood burner.

RV-4's cool all too well. I think you answered your question. Block oil cooler
and block inlet. Not sure how you are blocking inlet but block the inner edge
near the spinner. Make some aero shaped foam and tape it on. Crude but effective.
In cold weather it is hard to get the RV-4 oil hot. Don't forget to lean
below 75% power.
If you want to make some more substantial and permanent change a cowl flap would
be of benefit year round and make your RV faster. In an old RVator van shows
how to make a cowl flap. If you get the last 16 years or what ever of the RVator
it shows the concept. Blocking inlet and outlet has benefits. That is one
reason the Sam James style cowl makes RV's 6mph or more faster. The stock RV
cowl is a little fat on the inlet area for most operations. To be fair, van has
to account for worst case conditions in very hot weather and hard long climbs.
If you want to know more check out the Jamesaircraft yahoo group, and look
at the first message in the group for the reason the cowl makes you go faster,
while maintaining acceptable temps.

Subject: Cowl flap
Looking to make a cowl flap that I can operate from the cockpit for my RV-4.
Does anyone have any pictures or plan I might look at? I have my oil cooler
blocked with aluminum tape and also restricted the cowl inlets approximately
one third.
Finally got my oil heated up to 185 F. Without the cowl inlets
restricted, can only get about 120 F on the oil. Not sure whether to restrict
the inlet or outlet flow. Any advice? Thanks in advance.

--> RV-List message posted by: "Dick DeCramer" <diesel@rconnect.com>
I bought a piece of 1/2" rigid plastic PVC water pipe, some couplings (a
tee, 090 degree, straight coupling)and glue which are all are very cheap at
the local discount lumber yard. I used a 12" piece and notched it for a
fuel dipstick, made two wheel chokes by forming a "U" using 90 degree
couplings around each tire to fit beneath the wheel fairings as chocks, and
oil an dipstick wrench. The dipstick is a "T" handle about 12" long and
has a straight coupling to reinforce the bottom end with a cross notch cut
to fit the thumb ears on the Lycoming dipstick This enables a person to
easily reach deep into the cowl and still get enough leverage to loosen the
dipstick without messing up your shirt sleeve. These tools are all glued
together with PVC glue, weigh almost nothing, with a very little cost in
time and $$$ so I have a set in the baggage area and also in the hangar.
None of this tubing is clear rather it is a manila or off white but it is
just as functional and very readily available.

Mickey...
Why 1/8" SS? That's thick, tough and spendy to cut. I went to Target (Av
Dept. of course) and bought some cheap stainless cookware and made firewall and
exhaust shields from same. Pretty easy to cut with snips. After all, our
firewalls are only .020 or so... Another technique to cut thin stainless is to
go
up to .75" with a step drill, then hog it out with die grinder and sanding
drum (Harbor Freight) chucked in. This works well and leaves a clean hole.
Radio shack and other electronics stores sell a nice little nibbler tool for
$12 that makes short work of thin SS also...
I'd be happy to mail you some surplus thin SS I have, just tell me how much
you need. I have about a square foot I can spare...

I see the List Police are at it again! Chill out!!!!! I've been lurking
ont this list for a couple of years and I continually see people brought up
short for totally insignificant breaches of list etiquite (sp)? and a lot of
questionable and error ridden answers to questions. How do I know? I've
been a builder and mechanic for over 30 years. How about trying to keep the
chatter relevant to building and helping "newbies" with legitimate help.
