I am also interested in a flexible line setup. A fellow builder just
completed a 6a and was doing some high speed taxi testing. With heavy
braking he experienced the groaning and vibration reported here before.
The next day in the hangar, he noticed brake fluid on the floor beneath
this section of aluminum tubing. It had cracked on the inside of the bend.
The caliper is held in place by pins that allow it to float freely
sideways. When the break pads are not tight against the rotor the
caliper can be moved around quite a bit and is restricted in movement
partly by the aluminum break line. So, any movement of the caliper is
tranfered directly to the brake line. Bending metals causes them to
strain harden which is not what you want for something that could be
exposed to severe vibrations. I am interested in where you got your
fittings etc, (pictures?).

I was thinking the same thing, why switch from a known good fuel source to
a unknown, for lack of a better term. Then I thought about it, On a steep
decent with 3~5 gallons in the tank all that fuel could flow forward and
then you would be sucking air. Wonder if this is what happened? What would
be really interesting is to put say 5 gallons in the tank and then lift the
tail which would equal 10? degrees nose down and see if you can still pull
fuel.

What about the possibility of a relatively low fuel quantity in the tank and
a nose low descent. With our fuel pick-ups in the rear of the tank, has
anyone figured out the difference in useable fuel with a nose low attitude
versus a climb or normal cruise attitude.
Yes, this can happen. I have experienced engine sputtering with as much as
seven gallons in a nose low decent, especially if I am slipping and the
tank I am using is the low wing tank (this maneuver will unport the fuel
pickup and is common in other types of aicraft also). I have a fuel
injected system so I know it is "not carb ice", when the engine starts
running rough I immediately switch tanks, this always solves the problem.
Rules of thumb that I fly by:
1. I am always high on final, most of the time still at traffic pattern
altitude. With engine idle, full flaps and a slip, you can get a really
good sink rate ie. 1200-1500 fpm (if you really need it). I try and
maintain 80 kts.
2. I plan to land by using the fuel tank that will be in the higher wing,
ie when on a left hand traffic pattern, the right fuel tank is in the high
wing.
3. My favorite thing to do in my RV is practice engine outs at various
places in the traffic pattern. While in the pattern at pattern altitude, I
feel very confident that I can make a safe landing on the runway no matter
where the engine quits.
Caveat, my rules work for me and my aircraft, if these rules of thumb
bother you disregard.

Touch your carb some time when you have the engine uncowled just after
flight, as in oil-change time: mine gets too hot to leave your finger on for more
than a half-second. I was amazed the fuel in the carb float bowl didn't boil.
Not sure what effect the induction airflow of a running engine and cooling air
through the cowling in flight has on these temperature conditions, but agree
the carb gets a LOT of heat from the sump in a Lycoming. This always struck
me as very inefficient design, likened to operating with the carb heat on all
the time...

Hi All,
I'm just a student at this time (getting my x-country solos in - almost
there!), but this has been a concern of mine in the back of my head....and now
I read this.
In the Jepperson book it talks about what causes carb ice to form and how to
alleviate it. In particular, throttling back causes a high pressure
differential in the carb and a drastic temp drop - throw in vaporizing fuel and
humidity and you've got a bad recipe for disaster.
I'm being taught to perform GUMPCS and turning carb heat off to be followed by
throttleing back and decending through base and final.
If you ask me, carb heat should be applied during GUMPCS but the POH and
instructor say no. The POH says not to use CH due to possible detonation on
full power. I think I'd rather have some detonation than no power at all and
crash. Besides, I can either turn off CH or throttle back a little and get rid
of the detonation - correct? Those two alternatives are quicker responding
than letting the ice melt.
Cash, sorry to hear about your experience but glad you survived.

Okay, but I don't make any descents on final that way. I try to get the
plane slowed down to the back side of the power curve (1.3 x Vso), so it's more
like 10 degrees nose UP for a steep descent, and if it needs to be steeper
still, just pull the stick back more...

Oops, that name should be Cardinal not Pardinal Paint. This is an

Thanks for anyone's thoughts.

... why not just use -3 size Teflon braided flexible hose line
from the top of the gear leg all the way down to the caliper?? This
eliminates the need for a tube to hose fitting down by the caliper. No
need for bajo fittings, just use AN type fittings
The hoses can be bought pre-made here at a reasonable cost...
http://www.pegasusautoracing.com/pdfs/066.pdf
For fittings in -3 size, see...
http://www.pegasusautoracing.com/pdfs/072.pdf
Other RVs have been built this way..... many builders also use these hoses
as the link from the pilot's side brake actuators to the firewall - much
less bulky than the kit supplied hoses.

--> RV-List message posted by: "James E. Clark" <james@nextupventures.com>
GlacierSeveral of us have used the Ritchie M2 electronic compass in our
custom/homebuilt/experimental planes and they seem to work just fine.
The sensor is remote from the display and as soon as you turn it on, it
locks on to the correct heading.
The reason for this message is that a few people asked about how to get one
and I have found that Ritchie has put the program on the "back burner" (I
guess due to lack of interest from boaters) and are therefore not making
them at this time. There are many places that have them for $200+.
BUT ... I have found about 10 or so of these units and if there is interest,
I can purchase the entire lot. The price would be somewhere in the $100-$150
range, **definitely** less than $200.
Any interest??
If so, email me "off-list" with contact info. (james@nextupventures.com) .

Quite correct - flexing tubing beyond a certain amount will eventually
weaken it and cause a break.
However the RV plans (most any model) show a generous loop of aluminium
tubing around the axle before the AN-8XX which connects it to the wheel
caliper. The idea is that the 1/16" or so in/out movement in the brake
caliper will be spread over this 6"-8" length of tubing and keep the amount
of flexing quite small - below the fatigue limit of the material.
Too small a loop and/or damage such as a nick in the tube are more likely
the cause of a break in this area. The alternatives such as using some other
material or adding a short section of flex hose for the caliper joint are
likely to add weight, cost, and complexity and offer more leak
opportunities.
I would venture that the large majority of RVs flying use 1/4 aluminium tube
down to the caliper and are trouble free in this area.

It's probably back in Oregon by now. I talked to Rob Butt at Van's on
Tuesday and he helped pull the wings off at Osh and put it on a truck. The
wing spar was one of the early hand drilled type so any wing replacement
will be all new and drilled in place. At that time they weren't sure what
they were going to do with the plane, i.e. repair or salvage. The Lance
was totaled.

Not knocking your approaches its just thats not the way I was taught by
Mike S. We came in high, engine at idle and full flaps, put the numbers
just over the spinner and kept them there. This makes for a very steep
decent and thinking about it could really cause a problem if you cut it too
close on the fuel and only have a few gallons in one tank left.

When I talked with Mike, he indicated they were going to drive the 6
back to Van's place. they were looking at a new wing, motor mount and
engine stuff.
That was till.... somebody in a great haste to make pictures of the
broken 6 drove over Mike's >>up to then unharmed cowling<<, removed to
look at the motor mount....
Things people do to get pictures of accident scenes, even if it involves
friends. Just wondering what was so bleeding important to get those
pictures to cause Mike more damage.

hours that I flew it. A new owner has it now, and to my knowledge he hasn't
had any problems either. My RV-10 will also have flexible brake lines.

When the wheelpants departed the airplane, during my off airport landing, it
also ripped the aluminum mount from the brake to axle attachment. It did not
damage the aluminum brake line. My line is clamped to the front of the gear
leg with a loop around the leg then into the caliper. I wouldn't be to
concerned about cold working the tube as there is very little movement.

No, Scott, you certainly aren't knocking my approaches, you're describing
them :-)
I, too, was taught by the Great Santini, er, Seegar. I think we have a
failure to communicate...
Whether one flies airspeed or pitch attitude on final probably makes little
practical difference... I would guess you are seeing 65-70 mph IAS on final,
just as I am, with full flaps and that trademark steep RV approach. My prime
beef with this RV landing characteristic is that the nose will often obscure the
touchdown point since it must be held so high. The bottom line is: I never,
ever worry on final about fuel being too far forward in the tanks to reach the
pickup tube... a pitch attitude sufficient to do that would put my airspeed
well above the white arc in no time at all.
I'm not sure what part of this technique is supposed to be especailly
problematic in regards to a low fuel situation. Just remember to do any slips
away
from the tank you've selected. I typically land using the right tank, and make
any slips with left bank and right rudder. Fuel pressure goes up 1 psi just
from the ram effect (just kidding there!!!)

I called the factory and asked about pitch angle and uncovering the pick
up. They have never heard of it being a problem and "thought" a couple
gallons would be fine.
Thanks for sharing this situation/info with us, especially the decent rate
with engine out.

whoa! This is a new take on where carb ice forms.....I thought it formed at
the venturi in the carb long before the mixture passes through the tubes in
the oil sump. Doesn't it collect right about where the ice probe is
attached?
I also thought Lycomings were especially prone to carb ice because of 4
large cylinders sucking large volumes of air in short-fast cycles.
Please explain....

This switching tanks issue is why I *love* the fuel system on my -4. Engine
always draws fuel from the left tank. When I want to even the load I turn
on a Facit transfer pump which fills the left from the right. No fuel
selector valve. If I'm low on fuel I dump it all in the left tank. Very
comforting to know that I'll crash with no usable fuel : -) and totally
eliminates the "do I risk engine sputter now or later" conundrum.

At approximately 3 PM, RV-7A, N757X made its maiden flight of about .7 hrs
at Martin State Airport in Baltimore, MD. No surprises...a tad left wing
heavy. Now I can breathe again!
At this point I would be totally remiss if I were not to thank the people
that made this flight possible. Jack Fromm(an RV-8 Builder), who has the
most hands-on helping with the plane and who spent an enourmous amount of
hours these last weeks getting me through inspection and first flight.
Mitch(Chip) Lock(flying RV-7) who by far and away has the most time in
answering my stupid questions and who helped get my wing spars aligned when
they were off from the Phillipines. And last but by no means least Mike
Slate, friend and business partner who is responsible for all the stuff you
really see...windshield fairing, canopy fit, cowl fit, wheel pants...not to
mention getting the plane painted for me... Guys, I cannot thank you enough

With the prop windmilling there was not enough oil pressure to hold the prop
in coarse pitch. It automatically went to fine pitch.
Cash
This part troubles me. Somewhere I was lead to believe that there WOULD be
enough oil pressure to keep the prop in coarse pitch. Was it a Hartzell?
Would another constant speed prop behave any differently? Congratulations
on having and using the skill to get it on the ground safely.

In fact, take a look at the following :

The Ritchie M2, which is discontinued, has a white on blue face. I got one

call them they can try and locate a unit in a store close to you.
Call 1-800-boating (262 8464) and ask for part number 239320.
If you want a black and white face (either black on white or white on black)
and are willing to pay $100 more (US$195) look it up on:

But that will start flashing on, off, on, off for the 20 minutes that the
fuel level is around the trigger point of the switch. The dampening they
mention won't help much. But yes, it's a very cheap solution if you don't
mind all the flashing.

Subject: | EZ Pilot Digital Autopilot |
--> RV-List message posted by: Thomas Velvick <tomvelvick@cox.net>
I have been beta testing the EZ Pilot digital autopilot from Trio Avionics
(<http://www.trioavionics.com>www.trioavionics.com). It replaces the Navaid
AP gyro with a new digital head that has a lot more capabilities (if you
dont already have a Navaid, they will also include a servo). It
understands the NMEA sentence format from handheld GPSs as well as the
aviation format sentence from panel mount GPSs. This means you can get rid
of your smart coupler to connect a handheld gps. Since the EZ Pilot reads
the complete sentence output from the GPS it knows exactly where it is in
relation to the waypoints, not just the cross track error like the Navaid
uses. This allows it to fly the flight plan and anticipate each waypoint
as well as to fly intercepts and course reversals. The AP also has a two
line digital display that shows several parameters at one time such as ETE,
GPS groundspeed, Distance to Waypoint, ETC. In actual practice, my EZ
Pilot AP is now working excellent and handles turbulence better than the
Navaid does. Its also nice to look at the display and see your course
compared to the bearing to the waypoint and the distance in hundredth of a
mile you are off the centerline. It is normally flying within 0 to 50 feet
of the centerline. An additional digital gyro module is being developed as
an option for enhanced turbulence control. There are other features that I
haven't talked about. So if you are in the market for a digital autopilot
or want to upgrade your Navaid, here's another option.

..until you read this!
Control surfaces that use the AEX wedge and double flush trailing edge
rivets --7, 8, 9 rudders and 9 elevators and ailerons.
The article that Jim Cone put on the RV-Lists photo share on July 29th is
worth its weight in gold..or at least its weight in tail feather skins! If
you are going to do your rudder or elevators this weekend DON'T UNTIL YOU
READ JIM'S CONE'S ARTICLE!
I just finished one of my elevator trailing edges for the -9A this
afternoon and you almost can't tell which is the shop head and which is the
manufactured head on the rivets! I'll post some pictures later tonight,
IT'S REALLY THAT GOOD. There is a dark cloud to this silver lining..now
I'm going to have to buy new rudder skins so my TAIL FEATHERS WILL MATCH.

Subject: | Re: Ritchie M2 electronic compasses ... any interest???? |
--> RV-List message posted by: "James E. Clark" <james@nextupventures.com>
Amit is correct. [Thanks AMit for the additonal info.]
I want to be ABSOLUTELY CLEAR ... Ritchie stopped making the units.
Also, I am testing the need here ONLY because I was asked if I wanted to by
a dozen when I called to see what was the deal. I already have mine mounted
and over 180 hours on it. I also already have a spare.
Since a few people asked about them (including at OSH) I figured I would
test the waters so I did not end up making a purchase of something I did not
need and nobody else did either.
Anyone who has expressed an interest and would prefer the units listed
below, PLEASE let me know. I will in NO WAY be offended as I am just trying
to help out.
James

Subject: | need dimensions for 3ATI panel cutout |
--> RV-List message posted by: "C J Heitman" <cjh@execpc.com>
Does anyone know where I can find a dimensioned drawing of the proper panel
cutout for a 3-ATI instrument (as used on items such as a Sandel HSI - a
square cutout with the corners cut at 45 degrees). No luck with an archive
search or with a google search.

Harry-
Mine is the 5/8" and I converted the fitting on the engine to an AN one
that's also 5/8" to match, but if you want the 3/4" one that's otherwise identical
you can get it from Wicks. Don't know why ACS doesn't carry them.
FYI, the breather port on the big 6 cylinder Continentals is also 5/8".

Here's a quick and dirty page to show the results of using Jim Cone's
trailing edge rivet method. It's just the left elevator so it's a short
section. I'm going to do the right elevator probably on Saturday using
this method and I'll post the continuing results.

Micheal,
That technique works great! I discovered that technique about 2 1/2 years ago when
I was building my -9 rudder. I'm not sure if Jim picked it up from my page
or thought it up himself - brilliant minds think alike you know! (Now isn't that
arrogant! ;o) ) I recently borrowed my modified set to another -9 builder
to do the same. You can use it for the flaps and ailerons(on a -9) also because
they use the same AEX wedge with the same angle.
There's more details on my website at www.toddhoug.com - select "Squeezing double flush rivets" from the menu window on the left.
Good Luck,
Todd Houg
