Subject: RV10-List: Crushed oil filter
Here are a couple of pictures of my Kelly oil filter after about 35
hours. There were no engine oil pressure issues or any indication
that there was a problem with the filter. I was using straight
weight Aeroshell 80 and changed the oil in May so there were no cold
starts. I have switched back to Champion filters since that was my
SECOND Kelly filter to collapse. This month's Aviation Consumer has
an article on oil filters and rates the Kelly filter dead last. I
talked with Mattituck's engine guru, Mahlon Russel, at OSH and he
thought the problem was entirely with the filter.

I've replaced the old leakers with the stop leak tubes. Made by
either Michelin or Goodyear.
Remember to use talcum powder when putting the tubes inside the tires
and (from experience) slightly inflate the tube then mate the 2 wheel
halves to minimize potential to pinch (and tear) the tube when
torquing the wheel together.

Dave, I dropped the tires and tubes from my finish kit and purchased them from
Desser tire, which was mentioned by several other builders. I didn't pay too much
more than the Vans price, but got Goodyear flight custom tires, and the leak
proof tubes (the name was a little different than that though). They arrived
in a couple of days and they added in a big bag of tire talc too. I too am waiting
on Lord mounts. It looks like I am just going to have to get the credit
and buy them on my own if Vans is going to procure any to provide in the kits.

One positive about keeping Van's initial tires is that they're
not expensive tires.....and I think many people will be doing
a lot of re-learning or skills improving as they get used to
the new plane. My original tires I think lasted 300 hours
or so, and although I would have done better maybe with better
tires, it's kind of nice to have them be "expendable" tires
that you go with initially. Not that everyone will need this
or see it that way. I know I also went through the first set
of brakes faster. I'd highly recommend that once someone is
flying, you order a replacement set of brake linings right away
and keep them on hand. It'll be a while before you need them,
but some of these things you want to have ready because they
day you find that they're shot, you may want them done
immediately. So get the rivet tools, rivets, linings, and
things on hand early. Anyway, just wanted to point out that
having the cheap tires for the first part of your flying
might not be all that awful....you'll use many sets through
the plane's lifetime, so lots of opportunity to upgrade.

Looking at my untouched nose strut, I happened to notice a very subtle curve, or
bend, to it. If you put a straight edge on it, it has a constant curve to the
right. The gap between the straight edge and the tube is very small - only about
1/16", but it's definitely there.
Looking at the almost completed RV-10 next to me, the tube is straight. Perhaps
weight takes it out? Anybody seen or heard of this?

Van's does not have any Lord engine mounts. They are back ordered with
no delivery date in site. They gave me a Lord part number of J3804 but
looking at Spruce's site the number includes a -20 or -15 etc. Can
anyone tell me which part number to order? Or another source as
Spruce's price is $50 more per mount than Van's?
Also, I am about to put the plane on the gear. I have heard I should
install better tubes in the tires than what Van's supplies because they
leak. Which should I switch to and where to get them? Or are Van's
supplied good enough?

| Subject: | Re: Right Side Exterior Door Lock and Handle |
All the Cessnas that I'm use to flying have an external lock only on the left door.
You have to reach inside the cabin to unlock the right door.
I'm planning on following that model. e.g., right door will have an external handle
but will lock internally (I'll get a pin into the interior door handle which
will prevent the latch pin from being pushed in). Said pin to be removed while
in flight (emergency access issue).
Yes, this means in the left side, then walk around to the right, to help passengers
if needed. But I always get in first anyway, do pre-flight, etc., while passengers
watch from the shade (or stay in shelter from rain and cold)!
Not yet flying so this is all theory!

This is just how the tires wear on the RV-10's. Run them that way
and flip them 1/2 way through their life.

I had a nose gear problem as well. It looked like the vertical portion of
the nose gear strut was welded about 4 degrees off. I contacted Vans with
photos with plumb bob and digital angle finder and they agreed and replaced
it.

I wanted to see if we could get some data on the distance between the prop and
the ground when the prop is in the vertical position.
Why do you ask?
I want to know when I start to get some sag in the front rubber shocks. As I have
posted I have a shimmy in my main wheels. I talked to Ken and Van at Oshkosh
and they both said that shimmy in the main gears is common. Van said that
he had it as well and unfortunately there is not much I can do for toe-in. I
have talked to a few people about the design of the main gear and it is far from
being optimal. Van's words to me was that it is not the optimal design for
stiffness but they are inexpensive to manufacture. That is OK and I don't feel
like it is a safety issue.
Ken did say that you could re-align your gears and use a 7/16" bolt if you wanted
to try and change the toe-in.
Another factor that changes over time is the sag in the front gear which changes
the geometry of the toe-in as the front gear begins to drop.
Both the front gear leg sag and the application of the brakes causes more toe-out
to occur.
Depending on the results we get I may try to replace the front rubber bumpers.
I will also call Ken and try to get an engineered measurement.
Anyway, it is a number I wish I gathered before my first flight and tracked it
every year. Maybe we can decide on what an average number is.
Of course the prop will have to be the same size or we could just measure from
the center of the spinner down.
I will be at the hanger in the next night or two and will make the measurement.

If anyone decides to try and change the toe in give me a call. We did change
the toe in on my Glastar and the tires do not wear the outsides as the 10
does. The original procedure for alignment on the Glastar provided 3
degrees per side although the documentation specified procedure should have
produced 1/3 degree. We looked at the problem of toe in on the 10. One would
have to jack the aircraft and rotate the gear in the socket slightly and re
drill for a 7/16" bolt after using a pencil laser for measurement.

it is far from being optimal. Van's words to me was that it is not the
optimal design for stiffness but they are inexpensive to manufacture. That
is OK and I don't feel like it is a safety issue.
Ken did say that you could re-align your gears and use a 7/16" bolt if you
wanted to try and change the toe-in.
Another factor that changes over time is the sag in the front gear which
changes the geometry of the toe-in as the front gear begins to drop.
Both the front gear leg sag and the application of the brakes causes more
toe-out to occur.
Depending on the results we get I may try to replace the front rubber
bumpers. I will also call Ken and try to get an engineered measurement.
Anyway, it is a number I wish I gathered before my first flight and tracked
it every year. Maybe we can decide on what an average number is.
Of course the prop will have to be the same size or we could just measure
from the center of the spinner down.
I will be at the hanger in the next night or two and will make the
measurement.

I have a McMurdo Fastfind with GPS. The lithium battery reached its
expiration date. I . have been trying to determine the deterioration of the
battery over time. Unable to find the battery versus age graph I bought the
new battery good until 4/2015. I measured the voltage of the old battery at
11.92V. The PLB when deployed summons help by locating itself via GPS and
the broadcasting the info to a 406Mh satellite over the Atlantic or Pacific
and then to Suitland MD SAR. It also broadcasts on 121.5Mh for local VHF ADF
equipment. Response time from deployment until notification of SAR is
supposed to be about 2 minutes.

If it helps I remember the Decathlon at 2 degrees toe in and 2 degrees
bottom in.

If anyone decides to try and change the toe in give me a call. We did
change the toe in on my Glastar and the tires do not wear the outsides
as the 10 does. The original procedure for alignment on the Glastar
provided 3 degrees per side although the documentation specified
procedure should have produced 1/3 degree. We looked at the problem of
toe in on the 10. One would have to jack the aircraft and rotate the
gear in the socket slightly and re drill for a 7/16" bolt after using a
pencil laser for measurement.

I wanted to see if we could get some data on the distance between the
prop and the ground when the prop is in the vertical position.
Why do you ask?
I want to know when I start to get some sag in the front rubber
shocks. As I have posted I have a shimmy in my main wheels. I talked
to Ken and Van at Oshkosh and they both said that shimmy in the main
gears is common. Van said that he had it as well and unfortunately
there is not much I can do for toe-in. I have talked to a few people
about the design of the main gear and it is far from being optimal.
Van's words to me was that it is not the optimal design for stiffness
but they are inexpensive to manufacture. That is OK and I don't feel
like it is a safety issue.

David, would you elaborate on the laser part?
For those of us that haven't drilled the gear .... what should we do???

I will describe the Glastar procedure. To determine the actual toe in we
hung the aircraft on jacks and tail stand so that it was level a few inches
off the floor. Using a plumb bob we dropped a line from the elevator of the
aircraft perpendicular to the longitudinal axis of the aircraft. We also
measured the distance between the outboard faces of the main wheels. At that
point we shot a laser from a pencil laser taped to the outboard face of the
main wheels to the line below the aft elevator edge. At that point , if toe
in/out were zero we would have traced a large rectangle on the floor of the
hangar. What we had was a trapezoid where the base (aft ) was 115"(?) and
the top was 95"(?). By measuring the height (distance between main gear line
and elevator line we could determine the angles at the base and figure the
toe in/out. In our case it was toe in. IIRC the base angles were computed to
be about 87 degrees which meant that the toe in was 3 degrees. Because the
measurements are large , any angular error is reduced. We then (after
removing the bolt) rotated the gear leg in the socket and formed a near
rectangle on the hangar floor. At that point we clamp the gear legs in the
sockets, and proceeded to use a pencil grinder to open the weldment in the
direction of the needed adjustment. When sufficient material had been
removed we used a upsized drill ream to create d a new hole for a larger
bolt.

I might also add that this procedure was developed under the watchful eye of
a retired GM suspension engineer and fellow pilot. The Glastar people
continued to insist that their plans and procedure worked properly. Ask any
Glastar owner for an evaluation of tire wear

| Subject: | holes in control cable bracket |
Does anyone know the size of the holes in the control cable bracket for the
standard throttle, prop, mixture, and alt air controls? Need to paint/label
that part now, don't have the cables yet, and the size isn't noted in the
plans. Thanks for the help...
