Hello Everyone. I had my first flight yesterday. In fact two of
them! The plane left the ground so quick that I did not even get a
chance to notice the rotation speed. The only number I have for those
test flying theirs soon is that mine buffets at 57 kts.
I am in the process of breaking the engine and should be finished
today. Will post more numbers if there is an interest.

That is really awesome! You didn't give too much detail, but
I assume it was the normal "hands-off", "smooth", "flawless",
and everything else that we've heard about the -10's, right?
You'll quickly grow familiar with it and have more time to
see what's going on with the airframe and engine.
It's funny you say that about the rotation speed. I had a guy
who I let take off one day. He was a tiny bit nervous and
was asking "What's the rotation speed". I told him not to
worry about that, but just hold the nose 1" off the runway
and it would fly when it's time, and added "You won't be
at rotation speed long enough to see it." Boy was he
shocked when he took off. He went from parked to airborne
so fast he agreed that it's just a non-issue.
Good luck with all your fly-off. Hey, did they give you
25 or 40, and what engine/prop combo do you have?

Sorry, it was 4:00 AM when I wrote the note. My dog woke me up for
his required services an I was not 100% awake at the time.
You are correct. All the normal stuff, "hands off" etc. My second
flight seemed very routine.
Everyone at our airark was also shocked at the lift off performance
and the quitness of the engine.
I also remember lots of heat in the tunnel.
I haver an IO540 A4D5 (or whatever designation Van recommends) with
the Blended Airfoil prop. I have 25 hrs to test my plane. Today I am
continuing the engine break-in.
Perhaps we can compare some numbers once I have more data.

This topic was discussed in the past. I called the guy who posted the
subject. He is positive the heat is from the engine cooling which is in
the center of the lower cowling. He is also sure it is not the engine
exhaust. I look into venting my tunnel. Easy to vent at the rear to
let hot air out, but not so easy installing an inlet. I opted for
insulation. I made a false floor for the fuel pump assembly and
installed 1" of insulation along the bottom of the fuselage, full length
of the tunnel. One inch was too much below the torque tubes, used 1/4"
and 1/8" in those locations. I have not flown, so I can only hope this
works.
Thank You

David,
Don't take this with the wrong tone, as I don't mean it
as you might hear it, but....
Are you saying you've never heard of the tunnel heat issue
that was discussed in the past?
If so, I can try to post a short history and possible solutions.

When I flew 410RV at Lakeland airport, the tunnel is pretty darn hot, I said
something to Gus and he said it's warm but you get use to it...I'd guess
410's about hot enough at low altitude to burn your skin or irritate if you stay
in contact with it...don't know if anyone else noticed this or it was just me
looking for something...

This has been an ongoing problem, lot's of stuff in the archives about it. Not
sure if anyone has really determined 100% what the cause is but there has been
lot's of speculation and remediation techniques discussed. Some of the possible
problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he attached
the firewall cabin heat vent boxes which is probably a good idea. I used a
ceramic paint additive and painted the inside of the firewall, tunnel, and floor.
I also sprayed my acoustic material in the same areas which may add some
additional insulating capacity (doubtful but anything helps). I may also use
the standard firewall insulation but that stuff doesn't work very well unless
you can keep it completely air sealed against the firewall. The last thing I
am going to try to avoid this problem is to use insulated duct instead of regular
SCAT. The stuff is hard to find, and a lot more expensive, but heat is a
serious problem living in Texas (at least to someone from Wisconsin ;-)) and I
really want to keep it controlled.

This has been an ongoing problem, lot's of stuff in the archives about
it. Not sure if anyone has really determined 100% what the cause is but
there has been lot's of speculation and remediation techniques
discussed. Some of the possible problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he
attached the firewall cabin heat vent boxes which is probably a good
idea. I used a ceramic paint additive and painted the inside of the
firewall, tunnel, and floor. I also sprayed my acoustic material in the
same areas which may add some additional insulating capacity (doubtful
but anything helps). I may also use the standard firewall insulation
but that stuff doesn't work very well unless you can keep it completely
air sealed against the firewall. The last thing I am going to try to
avoid this problem is to use insulated duct instead of regular SCAT.
The stuff is hard to find, and a lot more expensive, but heat is a
serious problem living in Texas (at least to someone from Wisconsin ;-))
and I really want to keep it controlled.

There are many problems with the foam you mention over the years. The
RV gear leg/fairing voids pumped with foam ended up attacking the metal
gear rods and pitting them. I imagine water or trapped moisture was the
culprit here. Foam can be hydroscopic and absorb moisture. Cessna had
problems with foamed elevators absorbing water. Your door fill area
might not be a problem area with foam, however I wanted to bring these
points up for consideration

Fiber Glass thickness at Door Bottoms.
Bob, I took an epoxy syringe from west marine and drilled small holes
above
the joint and pumped in thickened epoxy, then just filled the holes
(#30).
It Ended up making a fillet inside the door frame. I also pumped in
expanding urethane foam into the larger cavities to insulate and glue.
Just
be careful not to guppy the thing....the expanding foam can easily
deform
the door. It didn't add much weight but it really seems to give the
door a
more solid feel...

Bobby,
Please help me understand, as I have trimmed my top but have not fitted
the doors. The doors are hinged on the roof and close (it appears) on
the bottom of the roof. I don't understand how not having the roof
flush to on the fuselage would effect the doors. It appears they can be
fitted even if the roof were sitting on a bench.
Thank You

Marcus,
Visited by another RV10 builder this afternoon. He quickly pointed out
my problem. The start of the problem was that I did not lower the cabin
top enough on the fuse. I left it up about 1/8" higher than it needed to
be. So guess where my missing 1/8" went. Not a big deal but I will need
to add it back to the bottom of the door and sand down and re-bevel the
bottom door frame. This will also give me the bottom edge needed to
place the door seal on the bottom of the door.

Bobby,
I too had to cut well inside the scribe lines so you may not have a
problem there as long as the door fits well. I commented to my self
several times that the scribe lines weren't all that accurate.
As for the separations you might want to try and just inject some resin
in the gaps rather than add glass which will be tough to get as smooth
as the door itself due to the extra thickness.

After sanding the doors into place I have almost no material left on the
bottom of the doors where they were glued together. I have some
separations that will require a couple of layers of glass to re-bond. I
am well inside the bottom scribe lines. Did anyone else need to sand
this far to make the doors fit. I have been looking at it for a week now
and I do not see where I could have done anything different except maybe
take more off the cabin top at the base of the doors.

Has anyone considered installing a small blast tube off the baffles and
dumping the air directly into the tunnel? Seems like coupling that with some
firewall insulation on the forward side would resolve the heat situation (or
am I missing something)?

Umm, where did I put that link. The problem I've had is finding anything insulated
in 2" and the only thing I have been able to come up with is a product
called Flex-vest. I can't seem to find a link that has a price again but most
sites that sell it will give a quote. I believe when I looked at it a couple
months ago it was around $20 a foot, yikes! Google Flex-vest and you should
get some hits. Here is an example link:
<http://www.flexaust.com/industrial/product_selector.asp?id=3D61&detail=3D1>
I might check with a local HVAC guy and see if there is something more common
for less money. I would think you could find some flexible & insulated ducting
near that size for the newer high velocity HVAC systems.
Another option is to take the standard SCAT and wrap it with common pipe insulating
wrap.

One problem with that solution is the air needs someplace to go. Either into
the cabin or back into the cowl. I will try to airseal my cabin as much as possible
to provide for a quieter and more controlled environment and have an exhaust
flap, if needed, (similar to what modern autos have) in the rear bulkhead.
Also, every additional firewall penetration will speed up a fire spreading into
the cockpit.
Someone suggested a small computer fan to circulate air through the tunnel.
This is probably the best idea after trying to prevent the heat as much as possible.

Rick,
This is my guess after reading that and trying to remember that step...
The door is positioned on the airframe using holes in tabs on the
outside edges of the doors in a couple spots. They go into rivet
holes in the fuselage.
So, if you don't trim the "threshold" area of the door (the underside
of it) enough, then it won't sit down on the fuselage as far as
it should. You would also likely notice that the seam of the canopy
to aluminum under the rear windows would tend to have a gap and
sit high, although it seems like it's a bit normal to have a small
amount more gap near the doors than at the rear of the canopy.
At any rate, if the canopy is high, but the doors are referenced to
the fuselage, then you'd end up with the doors in slightly the wrong
place on the canopy top.

Rick,
Since you put it that way it does not make since. My top sitting 1/8"
higher does not effect the door bottom fit. It made since yesterday
:)...... But removing material from the "top" of the bottom door frame
will still be required in my case. Thanks for the correction.

Bobby,
Please help me understand, as I have trimmed my top but have not fitted
the doors. The doors are hinged on the roof and close (it appears) on
the bottom of the roof. I don't understand how not having the roof
flush to on the fuselage would effect the doors. It appears they can be
fitted even if the roof were sitting on a bench.
Thank You

Marcus,
Visited by another RV10 builder this afternoon. He quickly pointed out
my problem. The start of the problem was that I did not lower the cabin
top enough on the fuse. I left it up about 1/8" higher than it needed to
be. So guess where my missing 1/8" went. Not a big deal but I will need
to add it back to the bottom of the door and sand down and re-bevel the
bottom door frame. This will also give me the bottom edge needed to
place the door seal on the bottom of the door.

Bobby,
I too had to cut well inside the scribe lines so you may not have a
problem there as long as the door fits well. I commented to my self
several times that the scribe lines weren't all that accurate.
As for the separations you might want to try and just inject some resin
in the gaps rather than add glass which will be tough to get as smooth
as the door itself due to the extra thickness.

After sanding the doors into place I have almost no material left on the
bottom of the doors where they were glued together. I have some
separations that will require a couple of layers of glass to re-bond. I
am well inside the bottom scribe lines. Did anyone else need to sand

Mike did a good job on this post. I personally see that the
heat from the exhaust, with the heater valve closed, would
tend to build up hot due to the slow moving hot air and small
leakage at the valve to the outside. Then those heater valve
boxes get hot, and it transfers into the tunnel area, esp.
by the firewall. When you're running cabin heat, you'd
maybe get a little less at the heater valve since the air
is flowing more, but you may get more radiating from the
SCAT in the tunnel area. Ventilating the tunnel may work, but
you would want to ensure no moisture enters or you may
end up with corrosion tendencies.
What I did was use 1/8" silicone baffle gasket material
to make a gasket between the heater box and firewall. This
should help prevent the metal to metal conductive transfer
a bit. I checked out Phenolic, but it's temp rating was
really low, and the silicone baffle is good for 500 deg +
or so. Then, in addition, I have a 1" or maybe it's 1.25"
SCAT flange attached to my right rear baffle and the SCAT
tube just runs down and connects to the firewall in a way
that allows it to blast air onto the heater valves. This
idea was had after talking to Randy, who was one of the few
people not reporting extremely hot tunnels. Randy had a
blast tube that ran to his fuel pump (engine mounted) if
I remember right, and he felt that maybe he had no problems
because the excess air from the fuel pump area was also
cooling the nearby vent boxes. So I tried to just use
a tube to do that directly. In my experience, on the SNF
trip, I pulled my shoes and was able to hold my foot against
the tunnel indefinitely, but it was still "hot". Some people
had reported it would definitely burn them, but mine is
not that hot. In addition, I have reflective firewall insulation
lining my tunnel which may help too.
Other things to consider: If your tunnel is hot, your fuel
lines in there will have a higher likelyhood of producing
fuel vapor. If you use the standard fuel valve, you
still may be fine, but during times when you use rear heat
you'll be running hot air next to your valve. In my install,
the SCAT runs next to only the long shaft that runs the
fuel valve.
One other builder got something like 6" exhaust extensions that
moved the exhaust away from the belly a bit. He said it
got cooler and quieter. I believe him, but, I think 6" would
be a little long, and the exhaust is still going to go right
past the bottom corner of the firewall....it's just going to
exit further away.
And a note on defroster fans. I had thought that I may want
to pipe hot air from the heater system or tunnel up to
my defroster fan. I don't think it's worth it anymore, and here's
why. In the winter you turn on the heat. The heat flows
up under the panel area anyway. My GRT EIS easily was reading
in the 90-110 deg. range in the panel. So all that hot
air is readily available to be blown on the windshield. I leave
my fan on year round, since in the summer it might be best to
exhaust some of that hot air from my avionics anyway.
So that's more than you wanted to read on heat today. ;)

This is not at all a precise measurement, but I'd guess that my
thickness of the threshold area of the door was about 3/16 to
1/4" thick at most. When you sand the bottom "lip" of the door
frame area off, it should be pretty thin and sit flat on the
aluminum door entry area.

Tim,
Below the bottom windows is where I am sitting 1/8" high. You
speculation about the holes use for fitting the door may be correct
after all. All I know is I will be add and removing more fiberglass :(

Rick,
This is my guess after reading that and trying to remember that step...
The door is positioned on the airframe using holes in tabs on the
outside edges of the doors in a couple spots. They go into rivet holes
in the fuselage.
So, if you don't trim the "threshold" area of the door (the underside of
it) enough, then it won't sit down on the fuselage as far as it should.
You would also likely notice that the seam of the canopy to aluminum
under the rear windows would tend to have a gap and sit high, although
it seems like it's a bit normal to have a small amount more gap near the
doors than at the rear of the canopy.
At any rate, if the canopy is high, but the doors are referenced to the
fuselage, then you'd end up with the doors in slightly the wrong place
on the canopy top.

Well....I'm not at that point of construction yet, but the tunnel heat does concern
me. Looking at many of the Rv10 projects on the web, it seems Van's has
the 2 triangular shaped heat valves (same one I have in my RV8) aiming the exhaust
port at each other. This hot air is always pointing at each other until
you open the valve for cabin heat.
Part of the tunnel heat problem could be as what Tim ond others have said...heat
conducting through the valve and radiating into the tunnel. Also, if the
heat valve(s) are the very same ones that I bought from Vans (I believe they are),
then they don't "seal" very well. If you have a blast of hot air aiming
at them constantly, (try experimenting with the valve in your hand and blow some
air with your air hose at the outlet side and see what happens) they could
possible leak and that hot air is forced down the tunnel through a "leaky" valve.
Maybe a solution would be to not point the exhaust ports at each other and/or
make a gasket to provide a better seal.
Just a thought but it's possible.

I am guessing mine is about 1/4". But the other builder who looked at it
said it was much thicker than his.

This is not at all a precise measurement, but I'd guess that my
thickness of the threshold area of the door was about 3/16 to 1/4" thick
at most. When you sand the bottom "lip" of the door frame area off, it
should be pretty thin and sit flat on the aluminum door entry area.

I taped my heater valves shut and the problem is essentially solved
for the time being. I think that the problem is in the valves. They
do not seal. After hearing of the problem, I even created a gasket to
seal the valves when they are shut. Apprently not good enough.
The solution might be in some talented person with a good machine shop
producing a valve with positive seal.

Rick,
This is my guess after reading that and trying to remember that step...
The door is positioned on the airframe using holes in tabs on the
outside edges of the doors in a couple spots. They go into rivet
holes in the fuselage.
So, if you don't trim the "threshold" area of the door (the underside
of it) enough, then it won't sit down on the fuselage as far as
it should. You would also likely notice that the seam of the canopy
to aluminum under the rear windows would tend to have a gap and
sit high, although it seems like it's a bit normal to have a small
amount more gap near the doors than at the rear of the canopy.
At any rate, if the canopy is high, but the doors are referenced to
the fuselage, then you'd end up with the doors in slightly the wrong
place on the canopy top.

I had been planning on a second valve as a "heat dump" so the firewall valve
is cold. After hearing this it sounds like this is an even better idea.
Really shutting off the heat has always been a problem in the -4. That
said, any of you that have the engine install done... is there room for
another T valve?

I have a hard time believing that the scat tubes are causing the tunnel to
get so hot. There is only heat going through them when the heater is on,
and then the air is flowing through into the cabin, so the cabin is also
heating up. Am I missing something?
I N256H we have not noticed any excessive heat in the tunnel and it has
flown over 200 hours. We haven=92t paid a lot of attention to it, but in that
much airtime, I would think the issue would show up. We didn=92t do anything
special to insulate it.

This has been an ongoing problem, lot's of stuff in the archives about it.
Not sure if anyone has really determined 100% what the cause is but there
has been lot's of speculation and remediation techniques discussed. Some of
the possible problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he
attached the firewall cabin heat vent boxes which is probably a good idea.
I used a ceramic paint additive and painted the inside of the firewall,
tunnel, and floor. I also sprayed my acoustic material in the same areas
which may add some additional insulating capacity (doubtful but anything
helps). I may also use the standard firewall insulation but that stuff
doesn't work very well unless you can keep it completely air sealed against
the firewall. The last thing I am going to try to avoid this problem is to
use insulated duct instead of regular SCAT. The stuff is hard to find, and
a lot more expensive, but heat is a serious problem living in Texas (at
least to someone from Wisconsin ;-)) and I really want to keep it
controlled.

What an airplane that the only thing we have to complain about or
discuss is a little extra heat in the tunnel!

I have a hard time believing that the scat tubes are causing the tunnel
to get so hot. There is only heat going through them when the heater is
on, and then the air is flowing through into the cabin, so the cabin is
also heating up. Am I missing something?
I N256H we have not noticed any excessive heat in the tunnel and it has
flown over 200 hours. We haven't paid a lot of attention to it, but in
that much airtime, I would think the issue would show up. We didn't do
anything special to insulate it.

This has been an ongoing problem, lot's of stuff in the archives about
it. Not sure if anyone has really determined 100% what the cause is but
there has been lot's of speculation and remediation techniques
discussed. Some of the possible problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he
attached the firewall cabin heat vent boxes which is probably a good
idea. I used a ceramic paint additive and painted the inside of the
firewall, tunnel, and floor. I also sprayed my acoustic material in the
same areas which may add some additional insulating capacity (doubtful
but anything helps). I may also use the standard firewall insulation
but that stuff doesn't work very well unless you can keep it completely
air sealed against the firewall. The last thing I am going to try to
avoid this problem is to use insulated duct instead of regular SCAT.
The stuff is hard to find, and a lot more expensive, but heat is a
serious problem living in Texas (at least to someone from Wisconsin ;-))
and I really want to keep it controlled.

Jesse,
If the vent boxes are leaking heated air into the SCAT it will indeed radiate
heat. Sounds like you got lucky and have some tightly closing vent boxes. Or
maybe much in the same way Randy doesn't have much of a problem, you did something
in the engine compartment to negate it. Like others have said it is probably
a combination of different things, but it is a problem and it does exist
on others -10's as has been reported.

We actually used some RTV and wax paper to seal the vents. When it is
cured, the wax paper is removed and the RTV stays on one part that will seal
against the other part. It seems to have worked.

Sorry if this has already been covered......I'm having a heck of a time finding
the six inch extension for the Andair valve. Do I have to get it from the folks
in the UK? I tried the distributors and listed in the US with no luck.
I bought the FS20X7. Is the extension universal?
Thanks for any direction.

We actually used some RTV and wax paper to seal the vents. When it is cured,
the wax paper is removed and the RTV stays on one part that will seal against
the other part. It seems to have worked.

Jesse,
If the vent boxes are leaking heated air into the SCAT it will indeed radiate
heat. Sounds like you got lucky and have some tightly closing vent boxes.
Or maybe much in the same way Randy doesn't have much of a problem, you did something
in the engine compartment to negate it. Like others have said it is
probably a combination of different things, but it is a problem and it does exist
on others -10's as has been reported.

I have a hard time believing that the scat tubes are causing the tunnel to get

This has been an ongoing problem, lot's of stuff in the archives about it.
Not sure if anyone has really determined 100% what the cause is but there has
been lot's of speculation and remediation techniques discussed. Some of the
possible problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he attached
the firewall cabin heat vent boxes which is probably a good idea. I used
a ceramic paint additive and painted the inside of the firewall, tunnel, and floor.
I also sprayed my acoustic material in the same areas which may add some
additional insulating capacity (doubtful but anything helps). I may also use
the standard firewall insulation but that stuff doesn't work very well unless
you can keep it completely air sealed against the firewall. The last thing
I am going to try to avoid this problem is to use insulated duct instead of regular
SCAT. The stuff is hard to find, and a lot more expensive, but heat is
a serious problem living in Texas (at least to someone from Wisconsin ;-)) and
I really want to keep it controlled.

Yep, you probably have to go direct for that. The extension is
the same for most valves, but you get a new handle and
engraved plate. You may or may not want the couplers depending
on your install.

Jesse, I am just fishing here. What exhaust system do you have? I have
the AWI system with one muffler running crosswise under the engine and
do not have a heating issue. Randy

Kevin - The Andair valves and extensions can be purchased separately and
joined at any time. One simply removed the original handle and replaces
it with a coupler.
Sean - I have two 6-inch extension kits for the FS20X7 on hand. $105
shipped.
Also available -
one FS20X7F ($235 shipped)
and several FS20F5FMF-Aux (for adding an Auxiliary tank - $225 shipped)

I do not know of anyone making an after market cabin. However, Sam
James of James Aircraft <http://www.jamesaircraft.com/About_Us.html> is
making an after market cowl for the 10.

And FWIW,
Neal was great to deal with for my Andair valve, good vendor, at least for my purchase.
I had it in hand in a few days.

I don't think that there is much room to accomodate another valve.
You will actaullay need two of them, one for the front duct and one
for the back.

I know this has been addressed before, but I was wondering if any of you
that opted to put the GPS antenna under the cowling have any feedback, good
or bad, on the idea? I suspect reception is okay, my biggest concern is the
heat in that area affecting the not so cheap antenna.

If you live in a cooler climate heat might not be an issue. Here, in
Florida, any small amount of heat will run you out of the cockpit.

This has been an ongoing problem, lot's of stuff in the archives about it.
Not sure if anyone has really determined 100% what the cause is but there
has been lot's of speculation and remediation techniques discussed. Some of
the possible problems are:
-Air leakage through the heat boxes on the firewall
-Radiated heat via the firewall
-Radiated heat from the exhaust/engine cooling
-radiated heat from the SCAT tube running through the tunnel
I believe Tim used silicon baffle material as a thermal break when he
attached the firewall cabin heat vent boxes which is probably a good idea.
I used a ceramic paint additive and painted the inside of the firewall,
tunnel, and floor. I also sprayed my acoustic material in the same areas
which may add some additional insulating capacity (doubtful but anything

doesn't work very well unless you can keep it completely air sealed against

| Subject: | GPS Antenna location |
I have checked the -10 archive and there is some confusing info there.
Both the Garmin and Comant antennas '. . . must be mounted on top of the aircraft . . . '[Comant ref and GNS430 Installation manual]. The Comant manual explicitly states a ground plane is NOT required. The GNS 430 does not say that a ground plane is required. The Comant reference http://www.comant.com/htmls/guide2.html even counsels against painting the antenna.
Why wouldn't the best place for a GPS antenna be on top of the cabin cover (just
aft of the windshield)? The antenna cable could be fed down through the WD-1043
Centre Cabin Brace (which could also serve as a local ground point).
I have heard (rumour only) that GPS satellite coverage is not the best in the southern
parts of Australia. Mounting the antenna under the cowl with airframe
obscuration behind may further compromise performance. Mounting the antenna
with the best view of the sky is the least risk option for me.

Ron,
You make an excellent point about the antenna on top of the cabin.
In
fact, I've been testing out my 480 by just having the antenna out in the
yard, clearly no ground plane, and it works fine. I think I'm going to
at
least try the "low drag" comm antenna from Van's ($7, what could go
wrong?)
for my secondary radio so now I wonder if having the comm antenna near
the

I have checked the -10 archive and there is some confusing info there.
Both the Garmin and Comant antennas '. . . must be mounted on top of the
aircraft . . . '[Comant ref and GNS430 Installation manual]. The Comant
manual explicitly states a ground plane is NOT required. The GNS 430
does
not say that a ground plane is required. The Comant reference
http://www.comant.com/htmls/guide2.html even counsels against painting
the
antenna.
Why wouldn't the best place for a GPS antenna be on top of the cabin
cover
(just aft of the windshield)? The antenna cable could be fed down
through
the WD-1043 Centre Cabin Brace (which could also serve as a local ground
point).
I have heard (rumour only) that GPS satellite coverage is not the best
in
the southern parts of Australia. Mounting the antenna under the cowl
with
airframe obscuration behind may further compromise performance.
Mounting
the antenna with the best view of the sky is the least risk option for
me.

I know this has been addressed before, but I was wondering if any of you
that opted to put the GPS antenna under the cowling have any feedback,
good
or bad, on the idea? I suspect reception is okay, my biggest concern is
the
heat in that area affecting the not so cheap antenna.

Can anyone explain why the "low drag" antenna shouldn't be called a "no

Ron,
You make an excellent point about the antenna on top of the cabin.
In
fact, I've been testing out my 480 by just having the antenna out in the
yard, clearly no ground plane, and it works fine. I think I'm going to
at
least try the "low drag" comm antenna from Van's ($7, what could go
wrong?)
for my secondary radio so now I wonder if having the comm antenna near
the
GPS antenna could be an issue. Perhaps I'm making this too hard, but
that's
half the fun I guess.

Now you should know that Tim....The thing probably weighs a few ounces,
and every ounce of weight in the plane will cause just that much more
drag as the angle of attack needs to compensate to lift it. You'd
probably still lose at least .000000001 Kt of speed by adding that
antenna, don'tcha think?

Is there any really good reason that it couldn't go on the upper forward
fuse skin right in front of the windshield and aft of the firewall? That
would not obstruct the pilot's view, and the cable would only need to be
about 18 inches or so. N256H has it on the glareshield inside the cabin
(avoids any problems with water getting in through a bad seal), and it works
great. Would it look terrible in front of the windshield?

I'm just throwing this out because no one else has mentioned it - I'm
putting my GPS antennas on the glareshield. The antennas will certainly have a
great view of the sky up through the plexi-glass, the install is easy and there
is no concern about engine heat cooking them.

Are you speaking of your current #40415 project or your father's #40241
(N256H) or both when you say "We Have"? Randy's thought that both #241
and his #006 had the earlier cross muffler design was a logical answer
to less of a problem comparison with either the valve design or scat
ductwork. Rather new twin muffler design.

I know this has been addressed before, but I was wondering if any of you
that opted to put the GPS antenna under the cowling have any feedback, good
or bad, on the idea? I suspect reception is okay, my biggest concern is
the heat in that area affecting the not so cheap antenna.
Thanks,
Marcus
