G'day all,
I am installing the flowscan sender at the moment. The sender mount
holes appear to be sized for an AN4 bolt, while the fuselage attach
bracket has nutplates for AN3. What's the go here - remove the mount
and install nutplates for AN4, or insert a bushing into the sender? I
received zero documentation from GRT on the floscan - is this normal?
cheers,
Ron

In July 2006 I insured with NationAir (underwritten by AIG). $3710.00
for $200,000 hull coverage. I am a 1500+ PVT INST rated pilot with in
excess of 300 hours RV-6A time and in excess of 1000+ High Performance

Has anybody come up with a good way to jack up the mains on the -10 without
taking the axle nut off and using something like Avery sells? For most
cases that works fine, but it would be nice to have another good way to do
it.

I used the same type of locks on my doors as Tim Olsen did, except I did
not put the lock into the door latch mechanism like Tim did.
I simply mounted the lock separately in the bottom of the door with the
lock's arm swinging down into a cut out in the door frame rail, very
similar to the baggage door lock assy.
Seems to work great so far.

I have the same problem on both counts. I ground/buffed the crack out of
the F-1010 this weekend but have decided that all rationality aside, it's
going to drive me crazy to install it like that so I'm just going to pay to
have a new one shipped. What's another $30 right?

I use a Harbor Freight 24" bottle jack. I grinded the top of the
piston to match an adopter (purchased form van or Avery) to fit the
jack. This adopter is 1/2 sphere and screws into the wing tie-down
with the eyebolt removed. I had to make a wooden base for the bottle
jack for stability. It kinda looks like the jacks you see at FBO
repair shops and lifts the wing.
Sorry I cannot be much more specific about the adopter. At my
age.....memory does not serve me well.
If you decide to go this route and need a picture of the adopter, I
will happy to supply you with one.

Jesse,
I borrowed a couple of jack stands from the hangar next door and jacked the
wings up at the tie down points. Worked well to get the mains off the
ground while fitting the wheel and gear leg fairings. Alex DeDominicis
sells a jack for the RV-10.

I just jacked mine up this past weekend to rotate the tires
on the rims because the outer tread on the tires was almost completely
wore off while the rest of the treads were almost new. I borrowed a set
of jack stands that they use for certified birds like Piper Arrows and
was going to jack it up using a bolt in the tie down ring, but I was
worried that with the span of these on the 10 it may not be able to
handle the force. So I used the stands under the center section spars
on the fuse with a =BD" board between the jack stands and the center
section spars. This worked great. Once the plane is painted I would
just make sure to have foam or something on the board to ensure not to
scratch the paint.
Thank You

I built these: http://www.myrv10.com/tips/generaltips.html
(see about 1/2 way down)
If someone's gonna own an RV-10 long term, they may as well
prepare by having the tools. Just used them last week
so I could replace my brakes, and I swapped the tires
on the rims from side to side (keeps the same rotation),
but I had to jack up both wheels at the same time.

I happen to be at that exact spot in building, as well. My F-1012B also does not
have pre-punched flanges, but it looks easy to match drill. As far as the F-1010
crack, mine has two gaps in the flange of the hole. It appears that it was
worked on. I'll check with Vans....

For the rest of you with this repetitive issue. Inspect all formed
parts and inform VANS within the prescribed time of receipt. A
defective formed part should be replaced at no additional purchase cost
to the Builder/Manufacturer. Shipping is another matter. This aircraft
has made a 125 million dollar economic impact to worldwide aviation,
already. It will only take a few defective parts working in harmony to
have a precipitous impact on insurance rates for the remaining
builder/manufacturers left with the project. They(VANS) may have to
resort to an RMA process and improved QC (internal) process which is
good for all concerned. Complacency or willingness to install such
parts is not a good thing. Ask your surviving spouses attorney.
$30 here, 100 there, if you see all the rejected canopies you begin to
get a picture of many builders actually doing a "Receipt Inspection".

Talked to Van's this am re F-1012B flange. It is intentionally not
PRE-drilled/punched so as to accommodate some variance in hole/skin

The AoA's are generally much better at showing stall information (when
was the last time you saw a jet with a stall tab). Because I am going
with the AoA Pro, I for one didn't see the point of putting the old
mechanical tab out there.

Hi Eric...
I finished my leading edges not that long ago. Instead of
ordering/installing any of the accessories, I left the outer rib
clecoed, so I could order and install accessories some time later.
With the stall warning gizmo, I had not even considered not installing
it, since it's such a useful thing to have. Are people just forgoing the
mechnical stall indicator, for the AOA, or replacing it with something
better?

I am getting ready to start the leading edges of my wings and plunk down

heated pitot, the Duckworks HID landing lights, and the AFS AOA. After
reviewing the archives several of you had said that you were putting the
light and the AOA on the last bay. Any feedback on how that worked out
as far as space and ease of maintenace for the future? I was also
looking at simply closing the stall horn holes and not installing it, as
others have done. Does any body flying think that is something I should
still install? Finally any other tips or gotchas out there. I have been

I had mine replaced by Vans at no charge. I did not have to send in the or

. I would not accept them with cracks. Although you might only see one cr
ack in the region there might be another area ready to crack after a few lo

Hey all -
I was perusing the archives looking for info on the transponder antenna
placement, and I ran across mentions of microwaves cooking private
parts. Really? Come on... really? I'm looking at spots to mount the
antenna, and under the pilot / copilot seats seems like the best bet for
me. The tunnel is out, because I made a false floor that goes from the
firewall to the spar and I don't want any penetrations there. I was
thinking the transponder antenna under the copilot and the avidyne/ryan
traffic antenna under the pilot seat. I've already got comms under the
rear passenger seats, and navs in the wingtips. Is the transponder
really going to do a number on me or my copilot under the seats?

Removing the obvious (the visible crack) does not remove the adjacent
induced stress which is yet to propagate. Many who have stop drilled
learn that lesson with time on their airframe after a perceived patch
was signed off. You are only cheating the inevitable. Metal has memory,
it does not forget. You are not going to fool it into long term
submission. We resort to Eddy Current and Ultrasonic more often that
people know with our air carrier aircraft.
The use of polarizing lens while watching the bending, drilling or
cutting of Plexiglas/acrylic panel is a real eye opener if you can
excuse the pun. The stresses can go wild. You can watch with dazzling
amazement at the exact moment just before the crack destroys the final
piece.
Replacing it with one (F-1010)that has not been manipulated or masked is
the "No brainer". You can consider it the Golden Panel too. Dip it in
alodine like Tim did and then tell stories about it in hangars, years
from now.

On the -9A I use an ATV/Motorcycle jack that I bought at Harbor
Freight. I made a wooden "truss" to take up the space between the
jack and the plane. By placing it directly under the main spar I can
lift the entire plane with just a pump of the lever. I normally only
raise it about an inch or so.

I have heard both....that it is harmful microwave energy from William Curtis who's

I can't speak to the sperm-count effect of the Transponder antenna, but if
you're out of the baby-making stage, then that might not matter anyway.
Let's go ahead and get the do not archive tag here.
I put mine on the tunnel just aft of the firewall, which allows for a very
short wiring run and keeps it away from the other cables and antennas. I
have the comms under the pilot and copilot. The main thing I would
recommend, if you are comfortable putting it under your seat, would be that
you have at least 30-36 inches between it and the comms, which shouldn't be
a big problem. Also, I understand that it is a good idea to keep the cable
run separate from your other antennas.

Not sure I follow the thinking here. Removing the visible tear simply
removes the tear which
could represent a focal point for local stresses. It is the most
likely place for any stresses to manifest
themselves in further tearing.
Without the tear, I'm thinking there is no focal point and no tear to
propogate. Whatever stresses exist
in the piece remain. Just because there isn't a tear in a replacement
part doesn't mean there isn't the same
set of stresses in the part. They just didn't result in a tear.
If you are saying that the tear induces stress and the metal remembers,
I guess I don't understand that.
In any case, the tear needs to be removed or possibly stop drilled. But
doing either compromises the original
intended strength of the piece so I agree it should be replaced.

peak output power rating of a transponder (100 to 250W)
and tried to make a connection between a desire to
make one's airplane visible to a distant radar receiver
and cooking meat.
When you buy a microwave, it too is rated in the
hundreds of watts . . . but CONTINUOUS duty. A
good 700W microwave will boil a cup of water in
about 2 minutes. (Remember the traveler's immersion
heaters in the hardware store? They're 300W heaters
and take about 4 minutes to boil a cup of water).
If you measure the current draw of this machine,
it will be on the order of 8-9 amps or 1000W total
input.
Your transponder draws about 1.5 amps while being
interrogated for a total input power of 18W. The
output comes in the form of a series of 0.5 uSec
pulses in respond to an interrogation that represent
a string of binary numbers representing either your
squawk code (mode A) or altitude (mode C). Assuming
you are interrogated once per second (quite often)
your average output power for a 250W transponder
is on the order of 250W x 20 pulses x 0.0000005
seconds/1 second or 2.5 milliwatts per second.
This isn't going even going to warm up much less cook
anything.
Another fallacy of the myth concerns body parts
most sensitive to microwave radiation . . . turns
out that your eyes are the most vulnerable . . .
but the story isn't nearly so interesting to
really macho pilots. None the less, there are
folks who have armor-shielded their seat bottoms
in deference to this myth. The story was REALLY
popular about 15 years ago in the heyday of
the Long-Ezs
Here's a post I did on a canard pusher list
server about 5 years ago:
> Location away from the pilot/co-pilot is also
>recommended but over ten feet requires a different cable. Yes?? I was
>thinking about locating it aft of the pilot in the baggage area. Is that
>distance safe?
A totally bogus recommendation. A few years back, someone observed
that their transponder was rated for 200 watts output . . . 1/3rd
that of the family microwave. Our hero was immediately concerned for
preservation of the family jewels and proceeded to line the bottom
of his composite seat pan with aluminum foil. What he failed to
understand was that his RF coffee warmer and popcorn popper was
rated in continuous watts while the transponder was in peak watts.
The average power output from a transponder is less than 1 watt . . .
BTW, the eyes are about 100 times more sensitive to the effects of
microwave heating than are any deep organs . . . you'll go blind
you quit making babies.

This goes along with the original scientific studies used in 1983, when
cell phones were first sold that said everyone was going to get brain
tumors on the side closest the antenna on your hand-held.
I think it led to a lot of brain dead teenagers but no tumorous growths
in their adult life - yet. However, there are a lot of EA-6B Naval
Aviators that swear their love life was curtailed by the errant
electrons bouncing off the gold electroplated canopies from all that
jamming they did for Uncle Sammy.
Rick I would think the Air Force used similar stories on the girls in
your day. Just don't forget about Blue Nads from those forward NACA
ducts.

Does the placement of the transponder antenna need to be as far forward
as possible, or am I making that up? I feel like I read that or heard
that somewhere. If I can put the antenna behind the bulkhead I'd love
it! is there a good argument (besides longer coax run) against putting

I don't know if the -10 uses standard threaded tie-down anchors or
not, but Mooney and I believe some other aircraft have threaded
jackpoints that are installed in place of the tie-down rings whenever
jacking is necessary. The underside of the jackpoint is milled conical
so that it mates right up with a standard aircraft jack, while
allowing relative freedom to pivot on the point while leveling or just
jacking one side.

If your com's are under the rear seats, having these antennas
so close may not be a good thing. I'm no expert, but I
do think they want 30+ inches or something like that, so
the more the better. The other suggestion of under
the tail seems OK though, despite the long cable run.
I opted to keep that cable short and put it in the tunnel.
Not sure if you could just do a penetration in your
false floor and grommet it to seal it up, but if you can
find a way to get it there, it's not a bad spot. Don't
put it way up right by the exhaust though....leave it back
a little.

It is threaded. Handy spot. As far as handling the load of
the plane, if the plane can't lift itself by the wings, and
handle that 1G, I'd be a bit worried about how it would handle
4G's.

Well many a night we did radar ops checks and had to actually transmit, I never
did trust those cones set out in front. I saw a guy throw a wad of steel wool
out in front and watched it burst into flames...yeah I know not so smart in a
slightly explosive enviroment but that convinced me that those invisible radio
waves really could do some damage if they were powerful enough. That was almost
as exciting as throwing a cement brick into an F-100 afterburner and watcing
the force of full AB throw the brick a good 400 feet. The noise and vibrations
off that AB was enough to make you feel sick to your stomach. All BTW you
could not "see"
Some truth to the term that what you can't see CAN hurt you. Of couse that leads
to why there is an eye patch on the stick of the Victor alert birds.....

Sounds like a good episode of Mythbusters. Adam can put his nads in a

Seriously though, I don't think anyone has ever done a serious study on
this. In reality any potential health issues are probably pretty small.
You probably get more rads from the solar radiation at 15,000 feet than
from the transponder. I still wouldn't put it right under my seat
though. The biggest issue in placement is keeping the antenna lead as
short as possible.

The antenna placement recommendations from Garmin are:
1. place antenna 3 feet (physical measurement) from transponder unit
2. cable no longer than 8.8 feet of RG-400 (to handle the high power)
3. 30 inches (physical measurement) from any com antenna
4. Try to maximize distance from landing gear leg when placing under the seat
to minimize
holes in pattern. Mine is too close but it works correctly.

Sounds like a good episode of Mythbusters. Adam can put his nads in a
microwave and Jamie can sit on a transponder antenna while being
regularly interrogated or pushing ident. ROFLMAO!
Seriously though, I don't think anyone has ever done a serious study on
this. In reality any potential health issues are probably pretty small.
You probably get more rads from the solar radiation at 15,000 feet than
from the transponder. I still wouldn't put it right under my seat
though. The biggest issue in placement is keeping the antenna lead as
short as possible.

| Subject: | truemap and motion m1300 outdoor tablet PC |
dear RV-ers.
About 3 years ago, I purchased a license for truemap software. It was
never used. It cost $595, and I presume that because it was never
activated, the folks there will be kind enough to transfer this to
anyone who wants to use it. (if not, I will take it back and refund the
money.) I also purchased a Motion M1300 tablet PC, *with outdoor
display*. the m1300 is almost the same thing as what they now sell as
their LE 1600 tablet, though the latter has bluetood tech, and a
fingerprint reader. the outdoor display is a *big* deal. w/o it, they
are cheap. the tablet was also barely used, plus I have some
accessories, like the extra keyboard---because I never ended up using
the truemap software. finally, I have two USB GPS receivers. (they
make sense, because a wireless consumes more power.)
alas, I don't need the system any more. I may list it on ebay in a week
or so. if you would like to purchase it, please drop me an email.
not the smartest purchase I ever made...
regards,
/ivo

Not having to do any testing myself ... ;-) ..... I'll side with bunk!
First of all, the energy just isn't there, and the average energy is
way lower than that so ..... make your own assessment. Lets face it
.... microwave ovens work on the resonant frequency of water molecules.
I haven't a clue what that frequency really is, but the transponder
frequency probably isn't anywhere close. I'd liken it to the cell
phone/tumor thingy.

do not archive .... because I just may be blowing smoke!

electronic knowledge I trust and that it's bunk. I mounted mine on the bottom
right side between the battery and the right sidewall behind the baggage
bulkhead. It's outta the way, it is a long coax run but at least it's not near
the nads, rumor or not ;)
