No.
I watched someone (an A&P/IA no less) use Pro-Seal to
glue small plexigalss windows into the cabin top of a
35' sail boat a couple of years ago. Within 6 months,
the Pro-Seal had pulled loose from the plexiglass, and
the windows were leaking. I personally would want to
use a product specifically designed for glueing
plexiglass/acrylic, and not a sealant for this.

Great point. I started out flying C-150s and Cherokees, got my multi
rating in a Seneca, flew Convairs, DC3s, DC8s, Boeing 727s, and so forth. A
few years ago I started flying Airbus A300s. All the airplanes mentioned
were equipped pretty much like a light twin of the 70's: two coms, two
navs, an ADF, a couple of DMEs and sometimes an Omega or lately a GPS. The
Airbus had a fairly capable autopilot and more automation. My point is that
we flew and still fly these 450 knot jets just like we did the piston twins,
as far as the equipment is concerned. Most of them are hand flown for the
approach and landing (with the exception of the A 300).
My company operates both B 727s and A300s. The thing I (and others) have
noticed is that those that use the automation of the A300 tend to lose their
basic skills...this becomes obvious when the automation (particularly in the
approach phase, but also whenever the autopilots take the day off) quits.
The guys moving from the old to the newer have MUCH less trouble than going
the other way. I'm not sure the automation in too large a dose isn't a bad
thing unless it can be made 100% reliable. Engine monitors and glass
cockpits are great, but only if you don't get lazy and get too reliant on
them for situational awareness.
Makes me break out in a cold sweat to think about doing without glass
cockpits and automation. Oh well, guess I'll go pack for my next trip in
the old creaky B727.
The above, firmly tongue in cheek, but still true. Do not archive.

You can find it by clicking on "Canopy Construction" on the main page. It

What's wrong with the old one. You can recondition them by heating to red
hot with a torch and then quenching in water. This will restore the
malleability of the copper. The same trick works on spark plug gaskets.

With copper, unlike steel or aluminum, quenching makes no difference. You
can let them air cool and get the same results.

Skylor,
The application sheet for the Sika product specifies an acrylic application,
Direct Glazing Adhesive, however one electronic search I did brought up a page
where Vans and Sika did not recommend use on aircraft canopies. The reason
given was the possibility of improper technique.
My thought is an adhesive rated at 450 psi applied to a canopy will probably
be as strong as aluminum pop rivets.

Sherman, where did you find the spec of 450 psi? The technical data sheet
for Sikaflex 295UV says 160psi tensile, 250psi shear.

--> RV-List message posted by: "REHughes" <hawk@digisys.net>
Beating this dead horse one more (and like you, I hope last) time...
My friend Maurie powered up his new TruTrak ADI on the bench this morning,
and the results of extensive testing are:
1. Tilt the ADI 30 degrees to the side on the bench. After a variable
small transient, the display reverted to the level centered position.
2. Tilt the unit on its side (90 deg roll angle). Same result, washed back
to level, centered and stayed there.
3. Rapid pitch to 20 degrees Nose Up and hold. After a slight upward
transient, went to level centered and stayed there.
Summary: No roll angle or pitch angle information is displayed by the unit.
It is NOT an attitude indicator.
Functionally it seems to be a Turn Coordinator with an integrated VSI.*
* There may be some inputs from roll or pitch acceleration cues used to
"quicken" the display, but they seem to go away as soon as the acceleration
is removed and a steady-state roll angle or pitch angle is established.

These requirements would probably only be satisfied by a milspec AH. I doubt any
of the commonly
available digital or vac units would come close. A vac unit fails all three.
Watch out for the verdigals though!

Nope, that's not it. Both the Jamestown page:
http://www.jamestowndistributors.com/xrefsik295uv.jsp
And the Sikaflex page:
http://www.sikaindustry.com/tds-ipd-sikaflex295uv-us.pdf
List the testing spec. as ASTM D412.
I'll email the Jamestown site and see what they say.

Doug,
The performance of the Dynon looks pretty good. It covers 360 degrees of
roll and pitch and the Horizon is always visible. Performance is sensitive
to high roll and pitch rates (the screen background goes gray but degraded
data is still displayed) but many Unusual Attitudes in IMC occur at fairly
slow rates, frequently because the pilot was diverting attention to some
other task.
It would be nice to get some performance reports from folks who have been
flying the various EFIS units now available.

Have seen many posts re engine monitors etc. Makes me wonder how we kept
em in the air when all we had was good judgment. Just for the heck of it about
2 yrs ago, I went thru the list of the 14 cherokees I flew in the 60's while
getting my ratings and found that out of 14, 13 were still flying and turns
out the 140 I got my Pvt checkride in at Okc was setting across the ramp from
me at Gwinette co .Also the 1954 Apache I got my multi in (tricky plane) was
still flying. What do they have in common with the RV's? Lycoming engines. Am
I the only lucky Rv driver who can keep her in the air (high time engine) whith
nothing but good judgment? Charlie Heathco

--> RV-List message posted by: "Vincent S. Himsl" <vhimsl@adelphia.net>
Hello,
There are many places where you just can't use the hand held de burring tool
from Avery. However, the cutting piece unscrews and fits the AVERY <1095 hex
adapter for deburring / c'sink> tool @ $10.00. This in turn fits any
cordless drill. I used it on my quick connect screwdriver bit extension for
a really long reach...in the beginning.
Now I just hit hard to get at places with sandpaper, prime (if necessary)
and move on.

I am getting close to working on the airfilter and carb heat on my 0360
RV7A. I seem to remember seeing a small heat muff on someones RV for
their carb heat. It is not the one on Van's site. Anybody know what I'm
talking about?

The Van's muff that sorta clamps onto one side of a pipe was
ineffective. I bought one from these folks recently:
http://www.aircraftexhaust.net/
It doesn't look like the picture on their website. E-mail or call them
and they'll e-mail you a picture. I think it was about $65. Although
I've yet to try it, it looks like it will work much better.
Pax,
Ed Holyoke

A data point:
Mounting up a KX-165 (6.25") over a pair of Terra separates (6.3"
overall). An .040 spacer on each side of the KX tray was about right to
make up the difference. It should have taken 2 .025" spacers so maybe
it's a touch over 6.3".
