we used to bond new Velcro to aluminum using EC1300 (possibly similar to 3M weatherstrip
adhesive?). Make sure to cut the corners/ends to as perfect a radius
as possible. Apply the adhesive in a continuous coating to both the velcro back
and the aluminum. After drying, re-activate the dried coating with MEK and
clamp in blocks/rub down. Allow ample time to ensure total fixturing before attempting
to separate. Note that this technique does not work with Velcro that
has the adhesive coating (shiny layer) already on the back side.
Can you put some rivets in it? Especially at the ends.

I had two problems with the ZAC-supplied fuel selector valve. 1) When I screwed
the right angle hose barb fittings into the valve body, one of them could not
be oriented correctly (by a long way). Not a product flaw, just the luck of
the draw. 2) I painted myself into a corner by fabricating the center console
panel, leaving the selector valve installation 'til last. As a result, I didn't
have enough room for the selector valve and its fittings.
My solution was to buy a new selector valve from Andair with banjo fittings. I
can make it fit, but I will have lower it about 5mm and rotate it 45 degrees.

Prop Selection for 0-235L2C
I am currently building a 601XL and I am using the Lycoming 0-235 L2C
118H.P.. Zenair told me they used a wooden Sensenich - 68 x 54 with this
engine which produced 148 mph @ 2500 rpm at sea level. The engine I am
using is out of my old Piper Tomahawk which had a metal Sensenich 72 x 54.
Does anyone have any other prop recommendations and performance info? Any
advice would be greatly appreciated. Thanks.

Not cheap, but you could use the Andair extension parts and retain the
original handle position and orientation using either valve. I'm extending
my Andair 5-Way valve down to the cokpit floor.

Regarding the bravado on the Varga Kachina being stressed for 6 G's you might want
to check the aircraft certification data. (Hint: this data is on the sheet
of paper that consitutes the POH for the Varga; should be in the aircraft)
In the Normal catagory it's +3.8 Gs and for the Utility catagory it's +4.4 Gs;
not 6 Gs. Seeing as how you are carrying passangers during your "dog fights"
you will most likely be in the Normal catagory and pulling your 3 Gs is putting
you near the designed certification load factor.
Let's hope your mechanic actually does a torque check of the 4 bolts that holds
each wing on that 30 year old airplane, during the annual inspection.

What I've done to deal with the problem is a combination approach. I "dirty up"
the sticky part of the Velcro by contact with my (clean) hands first to remove
excess goo. Then I brush on Weldwood contact adhesive to the Velcro and the
airframe part it will mount to. When that dries, I stick them together. That provides
a pretty good bond by itself. Then I drill through the Velcro and the
airframe part to place two A4 rivets at opposite ends of the Velcro. So far so
good.

Ed,
I made a rough template out of bristol board (about the same as manila folder material)
and fine tuned it by adding strips of masking tape to fit the curve.
I transferred this to the rear top skin and made the cut. It fit the stab leading
edge perfectly. I removed the stab and later riveted the rear top skin
in place. Still later, I tried to reinstall the stab - and I couldn't get it
in the beautifully coped rear edge of the rear top skin. I had already riveted
the stab attach brackets in place and that caused the conflict. I had to trim
off that masterful rear edge of the top skin, and make an aluminum filler
that could be attached with screws and plate nuts after the stab is in place.
Some posters (and ZAC) have said that this is not a problem. Just watch out!

| Subject: | Re: CH601 hung up in a tree |
Yep Jay. This is a concept that dentists are acutely aware of. It's
called path of insertion; we deal with it all the time on bridegework.
The dirty little secret is that the geometry of the stab attach brackets
will not allow the removal of the stab in any direction other than up or
forward. Since the rear top skin must fit very closely to the nose of
the stab, forward movement is out of the question. Since no one wants to
drill out the rivets holding the rear top skin or the stab brackets, the
only direction left for the stab is straight up. So if the rear top skin
is cut to curve over the nose of the stab you're screwed; it is on
forever and can't be removed short of major surgery. What you had to do
is the only way I can see other than making a fairly sloppy cut with a
lot of gap over the stab.
Therefore unless someone comes forward with a miracle solution, I'm
going ot make a very close fitting cut where the rear top skin fits
under the nose of the stab but from where it contacts the leading edge,
the skin will be cut almost straight upward. I will make a piece of .016
to connect from there back to the rudder fairing. that piece will rivet
to the rudder fairing and screw to nutplates at the rear top skin.
BTW I assume we have to make some sort of L brackets to secure the
rudder fairing to the top of the stab with nutplates but I haven't seen
any instructions regarding that. Have you? I'm sure they're written
somewhere, but where?
Got enough rain yet?

These are the numbers for Phil Maxson's 601XL (from the archives):
"Corvair, 164 cubic inch, front start, WW conversion, Elison EFS-3A Carb
Warp Drive Prop, Set to 8.5 degrees Empty Weight: 777 pounds Gross Weight:
1320 pounds Cruise Speed: 125 mph, 3100 rpm, Std atmospheric conditions,
gross weight Fuel Burn: 5.5 gph Other factors: nose wheel, no wheel pants,
no brake line fairings, no fairing on the steps Climb: 1200 fpm. This is the
first set-up I've tried. I want to put on wheel pants and fairings this
winter, as well as change the prop pitch a little. The climb performance is
overwhelming, but I believe it is robbing me of top end performance. I am
also interested in using an Sensenich wood prop, but I don't know when that
will happen."
Phil will probably chime in but you can reach him direct at
pmaxpmax(at)HOTMAIL.COM.
If you have missed it, Rick Lindstrom is doing a multi-part article in
Kitplanes magazine on his 601XL. It is now flying so you might contact him
for numbers.
Charles Leonard's 601XL just took to the air two weeks ago. Ask him what his
early impressions are are cleonard52(at)comcast.net.

P.S. You would be wise to keep Jeff ( <mailto:Afterfxllc@aol.com>
Afterfxllc@aol.com) at arm's length. He admits he is making and selling
rip-offs of William Wynne's designs and has been kicked-off the Corvaircraft

Rick,
When I worked at Learjet 27 years ago, we used Velcro to tack down the carpet's
in the cabin. the Velcro had a contact adhesive pre-applied to the back side.
Instead of using that adhesive, we applied a coat of a commercial contact cement
from a company called Kingston. The contact cement was applied to the aluminum
floor and the loop side, allowed to dry, then pressed together. The same
was done to the carpet back and the hook side - no sewing.
I still have some carpet that I made up that way 26 years ago and it is still holding
strong. With today's advances in adhesives, some of the commercial products
should do the job for you. Unfortunately, I have not kept up with the latest
technology so I can't tell you what to use. I am sure that someone on this
site will have that info.

Be aware. It seems to be in fashion for some Johnny-come-lately to sell
completed Corvair engines these days. There are people out there that think
just because they have put together a single engine (which I have
not)--following another guys plans-that qualifies them to now assemble and
sell them to others. Do your homework and assemble your engine yourself or
buy from someone with proven skills; a long track record of success; and
integrity that will stand behind there commitment to you (i.e William
Wynne). Those of us who have paid attention, for some time now, to the
movement, have seen problems crop up. There may be more still to come. Get
involved. Stay informed. Don't get left out when some charlatan--who is just
in it for a quick buck-decides to take his profits and leave town the next
time a problem arises or his engines begin showing problems.
