Hi Jim,
Going to Harrison Hot Springs? You'll love it! If you get a chance, stay at the
H.H. Springs Hotel, the big resort hotel (not to be confused with the many smaller
hotels). If you can't stay there, at least visit it with your bathing suit.
It is unbelievable! Hot tubs of various temperatures, swimming pools, some
of them are connected by hot streams, underwater lighting, and beautiful wooden
walkways. The hotel is spectacular and its setting is on the secluded shores
of Harrison Lake. Long walks on the beach and hikes in the surrounding mountains
make it a world class location that very few people know about. It is 25
mins. drive north of Chilliwack, but fly over the lake before you park at the
airport (CYCW). If you're staying a while at H.H.S. it might be cheaper to take
a taxi there instead of renting a car and leaving it parked for a few days.
You MUST also have pie at the Chilliwack airport restaurant overlooking the runway.
The pie is made daily and is considered by many to be the best in B.C. You
might think I have shares in H.H. Springs Resort, but unfortunately not, but
I've been twice and would love to go back. As for CYCW, well, I send my private
students to CYCW for pie on their long X-C. They have to do the trip twice
if they don't bring back any pie! Chilliwack is a growing town on the Trans-Canada
Highway and as a result should have a car rental agency, however not at
the airport (5 min. drive south of town).The natives are friendly, so it shouldn't
be a problem to get a ride into town from a fellow pilot at the restaurant.
Chilliwack has very reasonable prices on most things, so I imagine you'll get
a deal on the car.
Hope some of this drivel is useful.
Cheers,
Chris Carpenter

The "Simple Green" solution has already made the rounds on several other
aviation lists - like the Grumman Gang. While it most likely WILL remove the
bugs, it MAY also remove the metal! Word is, Simple Green reacts in a very
nasty way to corrode the aluminum. I've not experienced this first hand, but
there were loads of testimonials as well as a directive by the air
force/navy to not use this product on their aircraft (can't find the direct
quote). "Simple Green" itself does have comments on these issues on their
web site - http://www.simplegreen.com/faq.html check "aircraft" and
"aluminum".

Lemon Pledge, either spray or aerosol. Have used it on my Cherokee for years. And
makes them easier to get them off the next time!
Not to mention that it leaves your plane "Lemony Fresh"

It is my impression that the wood attached to the gear legs is more of a
DAMPENER than a stiffener. If that is the case, it would reduce the stress on
the
gear leg by not letting it build up energy. The resultant amplitude would
then be less than it would be without the dampeners.
I'm still following this thread trying to decide what to do.

Dear Dynon,
With regard to your request for input for a new EFIS...
Reliability, reliability, reliability. All the features, bells and whistles are
of no use if they don't work. A POwerupSelfTest that would display (in conversational
English) any system anomalies or discrepancies since the previous power
up.
That being said...
CDI/GS overlay with input from GPS, Vor/Loc/Glideslope receiver, and Marker Beacon
display.
Thanks for giving your customers a chance to provide design input.

Doug,
I would like a system that is simple. Few if any more "front end" features
than a steam gauge HSI.
As for the features embedded in the system to talk with other equipment, I
am not an avionics engineer, but it looks like you have some good equipment
interface comments here from others.
Airplanes are becoming too "feature rich" I fly with too many pilots who
make flying more difficult, not simpler, by trying to use the "features" in
all the magic they paid good money for.
This is a serious problem in our industry. The FAA has just announced a
rewrite of the Inst. Rating Practical Test Standards to address this, but
the FAA is still concerned as are the airframe manufacturers.
All the features that are available can add utility to an airplane, but the
problem is, they add workload too. Many IFR pleasure pilots that I see are
marginally current at best. For this crowd, they should be turning the toys
off when they fly IFR, not looking for more "features" to fiddle with. You
cannot install experience in the panel.
The VFR folks have no need for most of the toys they have and spend time
fiddling with them when they should be looking outside.
Sorry folks, but I get to fly in lots of airplanes with lots of pilots and
this is a widespread problem.
I vote for a simple system that works well and has a fair price like the
D-10.

Tailwinds,

So I made the mistake of watching TV and dimpling my elevator trim tab spar at
the same time and dimpled the flange the wrong direction. When I redimpled it
the right direction I heard a little ping as the metal went from flat to dimpled.
This I believe was the sound of cracks forming circumferentially on the
raised dimple. The cracks were only noticeable under a magnifying glass. It
didn't take too much poking with a tool to get the dimple to fail completely.
Van's said that redimpling is safe if no cracks form, and I noticed in the archive
that others have encountered the same reasonable recommendation. However,
in the case of the heavier gauge pieces, I recommend examining the metal closely
and then just order a new part like I did.

I have one Comat bent whip Com antenna mounted just aft of the battery box (next

Com antenna in my right wingtip. The Archer is not performing up to my specifications
and I want to put a second bent whip Comat Com antenna somewhere. My
first choice would be behind the first on the midline of the belly. If I put
it there, how far back do I need to place it? Are there other locations that
would be better? My hanger mate has one on the belly and one on the turtledeck.
I don't particularly like the idea of putting the antenna on the top.

Van hisself said so. I suppose I should have tested it to be sure that the
wings don't snap off but I haven't got to that yet.
What would testing consist of? Load to 1800 and pull 4.3 (?) G's to see if
wings fall off. If they do, set GW lower and retest.
Load to 1800 and land. If gear collapses, etc
Seriously, how would you determine what is safe? How did Van do it? Or is
gross weight more of a legal term?

Van had occaision to test the wings of an 8 a few years ago. He assembled
the wings to the carry thru and put the assy. up-side down on saw horses.
He the proceeded to load the underside surfaces with 25 lb. bags of
sand,equalally distributed. I don't remember the numbers but I believe he
showed that the wings would carry at least 130% of what he rated them at.

--> RV-List message posted by: Gary Zilik <zilik@excelgeo.com>
First of all I would like to thank everyone that tried to help us out
while away from home. Thanks, what a great bunch of people. Now the story.
It all started on a tiny island 600nm SE of Florida. Grand Turk island
(MBGT) for those that wish to find it on a map. One of the RV's was
giving a ride to the local Dive Master when the LASAR ignition light
started blinking. Subsequent ground checks proved that the right mag was
dead. A quick phone call to Unison and new mags were on their way to
KFPR in Florida. His wallet was also quite a bit lighter.
Since RVers are safety oriented folks a two ship flight (safety in
numbers) was dispatched on Saturday morning to retrieve the parts from
KFPR. All went well and after refueling, getting the parts and a little
breakfast we headed back over the turquoise waters to the islands. On
climb-out somewhere around 3000' the engine in 99PZ started missing and
generally running rough. Since we were not to far out I radioed the lead
ship that two was headed back and we both made the turn and landed
without incident.
I pulled the cowl, checked the plugs, checked all the connections
including plug wires and found nothing out of the ordinary. A 25 Square
ground run went well so we re-cowled the plane and again headed for the
islands. We made it a little further the second time. Running down the
coast of Florida and after ICAO flight plans were opened 99PZ started
missing again. I guess PZ was determined to stay over land. A quick
check again proved it was the EI side and not fuel or carb ice. Turning
off the mag would cause the engine to run real rough and pop and
sputter. My wifes eyes were as big as oranges by this time. I turned off
the EI and returned to KFPR again without any further incident. Lead
decided to keep going with the parts to fix the original plane.
We borrowed the local courtesy car and ran down to NAPA and bought 4 new
plugs for the EI side. After installing the plugs I started the engine
and now the EI side would not work at all. At least now it was a hard
failure and not an intermittent one. After checking into a local hotel I
found and internet access terminal with a bad keyboard and sent a plea
out to the RV-List for help. After getting Jeff Rose's number I called
him and discussed my problem. Jeff felt the culprit was the Hall effect
sensor and suggested checking the resistance of the pickup. Another trip
to NAPA and 20 bucks lighter I had their cheapest VOM in hand and
checked the resistance of the sensor. It was good. I started checking
all the connections again and found the red wire on the brain-box end of
the sensor cable was not connected to anything. I pull out my cell phone
and called Jeff and asked him what the red wire was. His reply was
"Thats the Sense wire". I had found my problem, or so I hoped. I
rummaged up a #22 butt splice (radio shack brand) and repaired the red
wire. Another ground run and the EI side now worked. The next test was t
see if it would work in flight.
We strapped ourselves in and took off. All systems reported normal so we
pointed the nose towards KCTY and points beyond and 9.5 hours of flying
later (two fuel stops) we arrived back home in Denver without the EI
ever missing a beat.

Doug,
First, I commend you on your request for input from the pilot/builder
community - I would like to see the same approach to designing avionics from
every company!
Many have requested lots of features, and they are all good ideas. I would
like to suggest going the other direction - having a very simple and cheap
alternative to todays (yesterdays?) gyros:
A simple stand-alone digital DG. a simple stand-alone AI, a simple digital
stand alone TC.
All with the same user interface we are used to (on an LCD panel though),
but much higher reliablity, lower price ($400 a peice? is that feasable?),
while smaller behind the panel, much lighter - that is exactly what we could
all use.
If you are looking into something less "conservative", then why not go
all-out radical, and try something completely new. how about a real time V-N
diagram? I'll send you a drawing of what I have in mind seperately (can't
send attachements to the list).
My thoughts.
Amit.

I don't particularly like the idea of putting the antenna on the top.

Ross on my RV-6 I have to com antennas mounted right in front of the
wing spar on each side of the cabin. I realize
you have the gear structure in this area but that location works very
well for me. I also have the transponder antenna
mounted in between the two com antennas.

Can't decide for you, but in my experience having several hundred hours
without them and then
installing them, I am much happier with them ON my RV-6.

| Subject: | What would your perfect EHSI look like? |
--> RV-List message posted by: "Bartrim, Todd" <Steve.Bartrim@canfor.com>
There has been a few great suggestions already, but the GPS question brings
up an opportunity. An interface with any of the existing products is likely
the best (cheapest) solution, however if the plan is to have it's own internal
GPS, then I'd like to suggest looking into the Russian GLONASS system. Use
of both GPS & GLONASS with position calculated from averaging the signals or
selecting the stronger signal(s) would provide greater accuracy and redundancy
in case of system failure.
I asked on the list about GLONASS a few years ago, but most of the replies
that I received claimed that it was not a serviceable system due to system
maintenance neglect, so I researched it a little further and found that on the
contrary, the Ruskies had just put up 2 new birds to replace aging satts. They
continue to have 24 satts in orbit just like the US GPS system. Unfortunately
most of the info I found was written in Russian.
Another one to consider, since any new product that you may be considering
developing is likely several years away, would be the proposed European Galileao
system due to become operational in 2008. This will be a commercial system
(versus military), with 3 meter accuracy for free and 3mm accuracy for a fee
(?? I know, I find this hard to believe too).
This is likely more than you'd like to consider for your proposed instrument,
but you asked and I'd love to see it.

Just a hint for you or whoever buys the Terra stuff. To fix an interrmittent display,
try spraying the display driver chips (near display) with Corrosion X.
Plasma displays use a relatively high voltage which leaks all over the board
(which Terra in their infinite wisdom did not conformal coat) in humid conditions.

I'm redoing the panel on my 6 soooo the Terra has got to go. The
transponder just passed a check about 2 months ago, and works great.
Which is more than I can say for the Comm.
The Comm transmits and receives great, but the digital display is
intermittent. It will work for weeks at a time then decide it doesn't
want to display anything for a day or two.
Not my idea of fun.
Both are about 3 years old and complete with trays and manuals.
pay the freight.
Please respond off list.

After installing my SD20 alternator on the vacuum pad of my 0-360-A1A, I find
there isn't sufficient clearance for Van's tachometer transducer to screw
onto the tachometer outlet on the back of my engine. I built my all electric

--> RV-List message posted by: "Jim Nolan" <jamespnolan@earthlink.net>
Listers,
I've read the comments about Gear Leg Stiffeners with interest. My RV4
doesn't have stiffeners and I wouldn't put them on, here's why.
Once I landed at Rochester to have breakfast at a restaurant called
Karen's. Now, to get to this restaurant you have to taxi over a neatly mowed
field. While I was taxing, my left wheel dropped into a gopher hole, The
airplane made an immediate left turn, 180 degrees. I figure the only thing
that saved my gear and motor mount, was the Whitman gear. If it had been
stiff, I probley would have had to replace more than just the wheelpant.
I realize that this could only happen to me, but for those with luck
like mine, here's another way to look at gear stiffeners.

| Subject: | Re: RV6/A Gross Weight.... |
--> RV-List message posted by: Kevin Horton <khorton01@rogers.com>
The whole thing was well covered in the RVator at the time. Van
hired an FAA Designated Engineering Representative to supervise the
static load testing. The static load tests were done to the FAR 23
aerobatic aircraft criteria, which require loading of 1.5 times the
loads at the in-flight load factor limit. In other words the sand
bags represented a load of 9g at the aerobatic gross weight. They
did two load cases - one representing 9g at the stall, and the other
representing 9g at the recommended VNE. The wing passed both cases -
i.e. it did not fail. FAR 23 allows the manufacturer to use a new
wing for each test case, as the wing may be damaged even though it
does not fail, so it could fail the next test. Van used the same
wing for both test cases.
It is not really practical for a builder to do such a test for a
number of reasons:
It takes a lot of knowledge to be able to calculate the correct load
distribution. I.e. how much weight, and how is it distributed on the
wing spanwise and chordwise. You need more than 9 times the aircraft
weight, as the tail produces a down force that the wing must also
counter too.
The wing will likely be weakened by such a severe test, so you would
not want to use the wing that will go on your aircraft. You would
need to build two sets of wings - one for the static test, and one to
fly.

3d ground terrain much like pcavionics has going for the ipaq
Alternate display for EFIS
Background display for engine gauges, with alert features when a value
exceeds limits
If a true GPS ground display the TFR/SFR displays found in anywheremap are
very nice and have saved my cute tush several times.
TCAS display from a GTX330

Peter,
What we did on our RV6 is to attach a short cable from the engine to the
pickup. The pickup is mounted on a "shelf" that also holds the GPS antenna
just under the cowl. Seems to work just fine.
I think I got the cable from the "Aviation" department of some place like
NAPA/AutoZone.
Email me if there are additional questions.
James
p.s. Since you are "all electric", do you have an EFIS or electronic engine
monitor along with Electronic Ignition? Many of these combinations allow for
RPM to be determined from counting pulses on the EI.
