The VPX does have a timer for how long a switch has been pressed. It will disable
that circuit if a switch is pressed for more than a preset length of time,
at which time you can control the circuit (trim or flaps) from the screen.

I don't believe it has a way to detect if a switch is on because you are
commanding it or its on because its stuck, it also has no timer to detect how
long a switch has been on. It fact I don't think there is a way to detect that
at all. It has no circuitry inside the switch, so all it knows is the switch
is on or off. If you know otherwise please point me to the pertinent section
in the manual.

Kind of a wash. You pay shipping to send one back and get new correct
wheel(and highly recommend axle) or you get credit for wheel at less
than 1:1 if you delete from order. I think the latter is less hassle.

Here is a handbook on lightning from NASA and industry. It was specifically geared
for small aircraft.
http://www.niar.twsu.edu/agate/Documents/Lightning/WP3.1-031027-043.pdfIt
An interesting quote from it "it is also important to note that many strike incidents
have been reported where no bona fide thunderstorms have been visually
observed or reported "
As far as RV's being brought down by lightning, not many hours have been accumulated
in rv's with experimental EFIS's and no vacuum artificial horizons in IMC
condition. Until recently, most small aircraft flying in IMC had vacuum systems,
and even certified EFIS systems that are in certified aircraft like Cessnas
with G1000 have vacuum systems. A lightning strike or other phenomena taking
the instrument panel out on these aircraft is not a catastrophic event and
will not get reported. The same event, in an all electric, experimental EFIS
aircraft might be a different story. I do not know how tolerant my EFIS is to
lightening strike, I have no information, therefore, I don't assume, I work
around it.
Another point is that if a person loses control in IMC and crashes due to lightning
strike taking out their all electric panel I don't think it would be reported
as such or one would even find out. There are many loss of control in IMC
accidents that are not explained. So there really isn't much data on this at
all to base a conclusion on.
As for the fiberglass roof on the RV10, I personally have a bunch of wires including
coaxial cable running above my head. Don't know how much it helps but that
small risk would take a lot of effort to mitigate I am not willing to do it.
How far do I want to take this? Simple for me, by installing a vacuum system I
mitigate this risk for relatively small effort and cost. I don't have to figure
out the unknowns. Don't have to assume. Its simple, its been proven over
decades, its cheap, it works when the lights go out. It fits my risk mitigation
criteria. So yes, the risk is low and so is the effort to guard against
it. Its like seat belts, the risk of me getting into an accident while driving
to work today is extremely low, but putting on my seat belt to make the accident
more survivable is not much of an effort.

low. [Wink]

GLOC, even by the ricochet of their own explosive ordnance, but never a lightning

I don't think thats true Jesse. I have personally asked him about incorporating
a 3 second limit at Sun-n-Fun. He said that it could be incorporated but he
didn't seem too enthusiastic about it. He said "3 seconds is a long time."
If enough people ask for it he might incorporate it in future revisions of the
software. If you know otherwise please point me to the location where it states
that.

You are right. That was a feature that they advertised early in the company, where
the flaps or trim would cancel if pressed for 15 seconds or something like
that. Now, it tells you when the trim or flaps are running, and pushing the opposite
switch for 3 seconds will disable that circuit. They apparently replaced
the feature I was talking about with the above, as well as disabling all trims
and flaps if a switch is active during boot-up. I will request that feature
too, as I thought I had it already.

Maybe not a lot of initial labor effort, but you are looking at approx.
$5-600 in vacuum system, $700 for vacuum art. horizon, both of which have
500 mean time before failure estimates, at which time you get to spend
another $1000 replacing them, along with more labor to clean the lines of
carbon dust, along with annual filter changes. Not exactly low cost or low
effort in the long run. More money and effort if you elect to use more
reliable wet vacuum pump over a dry pump. Or you could spend about the same
money for a backup EFIS that likely will last 4 times longer (or more) than
the vacuum pump items.

So I skipped a year..4th year (little over 100 hours run time). Filter was

Clean the main fuel filter annually, and more often if you fly much
more than 100 hours/year.
It probably won't show much dirt from year to year, but it's a mistake
to assume the build-up is proportional to time. What you're looking
for is a big slug of something that got into the fuel tank somehow.
That could come from a fuel pump or truck at any time, maybe right
after the last time you cleaned the filter.
Remember, there's a second filter in the fuel servo, too!

I suspect a lot depends on how well the builder flushes the tanks prior to
use. I flushed multiple times before use and found a few small grains at 300
hours in the filter ; I also found a couple of aluminum
fragments that clogged the fuel sump drain at about 500 hours..

A big slug would be caught by the finger strainer in the tank if it even made it
to the wing root. If you are getting leaking tank sumps, that is an indication
that there is crud in the bottom of the tank. If you are getting a lot of that,
then the filter probably is getting more debris than normal. As was mentioned,
Airflow Performance has said that it would be very hard to clog their filter.
I check them periodically, but not every year. The most I have ever found
in one was a little bit of "lint".

My first check was at annual at 200
hours. Only a small amount of lint and a couple of tiny proseal particles. I will
check every annual for piece of mind.

Airflow Performance has said that it would be very hard to clog their
filter. I check them periodically, but not every year. The most I have ever found
in one was a little bit of "lint".

I used half mineral oil and half aviation gas; five gallons sloshed multiple
times into each and drained through the open tank sump hole. Found numerous
bits of proseal from QB tanks. Even that did not get it all; also found
aluminum shavings which caused the fuel sump to stick open and leak. It was
not the O-ring but two small aluminum chips holding the valve partially
open. Recommend getting an additional fuel sump valve and O-rings to carry
along, since you never know when leak will occur and for what reason. I
carry two already O-ringed and fuel lubed to install should a leak occur. It
is pretty tough to change one if you do not have a spare. They are just
swapped on the fly and you lose a few ounces of gas. Have the new valve and
1/2" wrench ready.

Sorry I misidentified Albany, OR as S67 (Nampa) when it's really S12. Got to meet
Rv-10r Ron Terharr but his plane was not on the field. Great paintjob however.
Really nice RV-12 there also, looks like RVs are alive and well there.

Risk analysis is a tricky business, because everything effects everything else.
For example, you might encounter a microburst - one that you could have out-climbed
except for the extra weight, and slight HP loss, of a vacuum pump. Or the
pump's shear shaft could fail to shear when it was supposed to, and a vane
breakage and pump jam lead to internal damage and failure of the engine. Or, the
finite lifetime of vacuum pumps leads to more frequent work around the engine.
Every once in a while the gasket is forgotten, or defective, or over or under
torqued, resulting in loss of engine oil and engine seizure. Or the mechanic
just leaves a wrench on top of the engine, causing mayhem later.
Very low probabilities, for sure. But so, apparently are lightning strikes. With
such low statistics it's very hard to say for certain that one approach is more
risk adverse than another. But my opinion - just my 2 cents - is that maintenance
activities introduce risk, more than lightning does (at least as long
as you make an effort to avoid the latter). In point of fact, I think GA would
be slightly safer if airframes were only inspected every other year (for aircraft
flying less than some amount, say, 300 hours). I think annuals cause more
problems than they find. (I'd advocate looking at the engine every year).

Couple of things to keep in mind. First, it only takes a few ounces of bad gas/contaminant
to restrict your flow. Your motor will run rough or not at all.
Seldom will it plug and let no gas thru.
Second, you only have one filter for both tanks, so when the filter restricts flow
from right tank, switching to the left will not help. That begs the question..........has
anyone put in two filters? One in right tank feed line and one
in the left tank feed line..........maybe in wing root and eliminate the one
in the tunnel. This would truly give you backup fuel flow if one filter was
restricted.
Also, DO not trust your eyes to verify filter is clean. We had a plane on the
field that landed with symptoms of fuel starvation. They looked at the filter
SS mesh 70 micron and it was clean. It had been cleaned/inspected 20 hours
earlier. Yet when then did a flow test it was only 45% of normal flow rate.
After putting in a new filter, pressure and flow were perfect.
Moral of checking/changing fuel filter: Fan on plane not run well with no/low
fuel flow!
Just my 2cents,
Dean
Fly safe!

Prior to first flight, I completely filled up one tank with 5 gal jugs of car
gas Then drained the tank into the jugs with an inline glass filter connected
to the drain port with a hose. I then used the filtered fuel in the other tank.
Found proseal and minor stuff. I then used the filtered gas in my cars.

I used two filters for the fuel system, one at each wing root. I can
inspect and clean them by removing the wing root covers. (which takes
all of 10 minutes)
I used the andair gas filter/collators, however I decided to NOT put in
sump-able drains, but rather plug the bottom fitting. I wanted no
chance of ever drawing air in since this part would be in vacuum with
respect to outside air pressure, therefore, sucking air means no fuel
flow.
So far so good. and no need to work inside the tunnel on a regular
basis.
Regarding cleaning, we have the same filter on our glastar (13 years
now), it gets cleaned at every annual condition inspection.
Here is a link to pictures in my picasa album with the pictures.

Properly vented your tanks should always be at very close to atmospheric
pressure, with any drain point at positive pressure for the head of fuel
over it. Thus a vacuum would only occur if the vent became plugged some
how.
