Subject: | Re: Nav antenna location?/200 mph |
Tony
Thank you for the reply. That sounds like a reasonable way to proceed,
given the info from ZAC. I suspect they increased the gross to 1320 in
response to the release of sport aircraft limits (no doubt as a result of
static load tests). But, I'd like to know why they changed the Vne.
I am confident that the XL at 160 mph is well within it's safety envelope,
but excessive wing load is a serious matter, see "Faulty ADM Kills" in
http://overtheairwaves.com/vol3-20final.html
for an extreme example of the consequences.

I cut down two FM whip antennas to about 26" (a little shorter than a
1/4 wavelength at the middle of the VOR band) and mounted them at
about 120 in a 3/4 inch PVC pipe cap. I used a "bazooka" balun. The
reception is pretty good.

Subject: | Re: A Series Continentals |
Dave,
Thanks, I have the orig. continental repair/parts manual. Will study it this
week. If the job is as easy as you say, I may change the engine before DAR
time. If it appears that it will take me to long to get done (I am slow), I
will get the airworthiness inspection done, fly off the airplane and then
change the engine. We are at 2,600' +/-. The A-65 appears to be good for
this airplane. I cannot hold the airplane with full throttle - unless it is
tied down. Wants to "skip" on the pavement with the brakes held tight. That
is at 2200 rpm. Gonna re-check/adjust the brakes tomorrow morning and see if
anything changes.

As for placement I tried 12%, 10%, and 8%. I settled on 8 %(LE of VG at
147mm forward of rivet line on top of spar on my plane). 12% was too far
back. At 10% on an extremely aggressive takeoff rotation the vgs would
occasionally "uncover" and result in an extended takeoff roll. I haven't
been able to force this situation at 8%.
I would stress that it is important to do your own flight testing before
making this commitment as each of these planes is different and your
results may vary considerably from mine.
Good Luck

Hi Terry,
I've had the u-nuts and j-nuts in service for over 2 years and can find
no signs of galvanic action on them or the cad plated steel screws.
Nothing was done to address the problem, but again, as the forward top
skin has been off a 3 or 4 times this past 2 years, there is no evidence
of corrosion. I don't believe there is any potential, unless the
aircraft was constantly exposed to rain and snow or the plane had to set
in a hangar within a mile of ocean salt air. I see they've been
phosphate treated and that's probably why they
are without corrosive activity.

Subject: | Re: Landing Light Lens Trimming |
Brad-
1. I put duct tape on both sides (Front+back) of the cut line and cut
with a fine blade and high speed on my bandsaw. Leave a little extra stock
for the inevitable little chips and finish up with a belt or disc sander.
2. I went down to the local hardware store and bought a batch of springs
of differing lengths and compression strengths to compensate for the final
lens mount angle. It's a lot easier to install a short spring where
necessary than to try to install longer, "One size fits all" springs. Hope
this helps.

hi list
i am trying to finish my canopy so i can send the fuse
out for paint. i have avioded this step for as long
as i can, but must get over this final hurdle. to me,
this is the most difficult and illogical part to
complete. nothing seems to progress in any rational
pattern.
i now believe that in order to have the thing fit
right, i will have to do major triming on one side of
the plexiglass. the manual suggests that some triming
will be needed to fit the open/close lever.
i am going to put it on and trim one side so it fits
evenly over the left and right rail. i will do this
unless someone out there has a trick or believes i
have made some major mistake in my construction of the
machine. i would gladly have paid extra to have a
completed canopy section sent. this part is far from
an exact science.
perhaps i am just getting frustrated as i thought i
was near completion. those tubes drive me crazy.
any comments or suggestions would be welcomed

Subject: | CH601XL center spar webs - drilling six 1/4" holes |
Newbie here.
I'm making my center spar webs at the moment and I made a mistake by flaring the
holes in the web before laying out and drilling the six 1/4" bolt holes. I'm
thinking of correcting this by placing a piece of 3/4" MDF board in between the
two webs (with a hole cut out of the board for clearance of the flared holes),
clamping the whole thing together tightly, with the two flanges set against
each other as specified in the plans, just with a 3/4" board offset instead
of being flat against each other, and then drilling the 1/4" holes. Does this
sound like a reasonbly safe method for getting the holes aligned properly? Seems
to me, drilled either way, that the piece would still be floppy enough before
being mounted in the fuselage to allow enough play to get all 6 bolts in place
properly.

Subject: | Re: RE : Questions About Bending Brake |
I have an 8'+ bending brake I made out of 1/4" thick by 3 1/2" steel angle made
with the same bending pivot idea as Zenith's brake. Despite what they say, you
can extended that brake to a full 8', you just need to beef it up externally.
I can bend .032 no problem. .040 I need a couple extra clamps in the middle,
but evereything below .032 is a piece of cake and straight. My brake desing
also allows for full depth bending (ie. rudder skin etc...) because the clamp
attach points are at the ends, no in the middle. Again, beefing it up externally
like a real brake is the key. The brake I have only cost about $300 including
the materials for the dolly and doesn't require any special machining operations
(no milling, no lathe work). You can make it with a metal cutting band saw,
drill press, hand grinder, and assorted basic hand tools. No welding required
at the joints either. The only welds I have on it are where the bow tensions
are mounted to the bows, and I'm sure something else could be done there too
or taken to a welder for $10. Perfect for sheet up to .032 (did my web spars
on it, al within 1mm) and good for .040 shallow depth sheet (stiffener L's etc...)
with a few extra clamps. No need to file a 1/8 radius either. It was already
on the steel by default. Just cleaned up the edge. Truly a handy thing to
have around the shop a problem free 8' bending brake for around $300.

Another canopy question-
I'm ready to start on the canopy, but am limited presently by a low 7'6"
ceiling. I'm thinking of putting the fuse flat on the floor with the gear
removed, and wondering if that will allow enough head room. Can the canopy
be properly fitted without having to open it fully? How high is it above the
top longerons when open?

Hi all,
I am wondering the source scratch builders are getting their 3/4 x 3/4 x
.093
Aluminum angle. Spruce has 3/4x3/4x1/8. I screwed up my elevator horn
doubler 6t3-6 by trimming off to much and was thinking that some raw
materials around the shop would be a good thing.
All this talk from the scratch builders has me thinking, that I should be
able to recover from some mistakes that are simple. maybe a couple of small
sheets or .040 and .032. To form some common parts.
Is there such a thing as a hybrid builder out there?
Thanks
Ernie.

I can take a picture if you like. There was in fact a round edge on it. On all
the pieces in fact. If it's 1/4" thick, and the edge is round, it's therefore
a 1/8" radius. I just cleaned any rust and high spots off of it before using it.
No need to file a 1/8" radius, it was already there. Even Zenith's brake per
the plans made a mention of a 1/8" radius already on the steel angle and to
just clean it up.

No problem.
Not sure what you're talking about with the aluminum having a radius.
I should pos some pix of my brake. I did a lot of thinking about this when I made
it and agonized over it. Not having a good qaulity large brake available to
me really put a damper on trying to get started on building a plane in the first
place. I'm happy with it. It's worked well and very versatile.

I bought a kit and like everyone else, or at least most, I screw up a
part now and then and not only does it get expensive but a lot of time
is lost waiting on replacement parts. Recently I bought 4' x 4' sheets
of .025, .032, .040 and .063 and I am really glad I did, I have used it
several times. Sometimes it is replacement for a part that is clearly
scrap, other times for a marginal part that bugs the hell out of me. I
wish I had done it sooner, it would have saved me a fair amount of money
and a lot of time.

Hi all,
I am wondering the source scratch builders are getting their 3/4 x 3/4
x .093
Aluminum angle. Spruce has 3/4x3/4x1/8. I screwed up my elevator horn
doubler 6t3-6 by trimming off to much and was thinking that some raw
materials around the shop would be a good thing.
All this talk from the scratch builders has me thinking, that I should
be able to recover from some mistakes that are simple. maybe a couple of
small sheets or .040 and .032. To form some common parts.
Is there such a thing as a hybrid builder out there?
Thanks
Ernie.

Any "honest" builder will own up to messing up some part or the other. Yes, sometimes,
it is best to go to ZAC for another part; but most of the time it is
easier (and definitely quicker) to fabricate another part yourself. I have probably
made a dozen replacement parts (confession is good for the soul, I am told).
Get over your "boo-boo", set your mind to it, recover and move on.

That's what I was going to say. Doesn't matter if it's in a jig or the spar. The
holes should be PERFECTLY aligned (by jigging the center spar to a wing spar
and drilling through both and then reaming through both).

Hi Ernie,
What I have done is to replace man kit parts I screwed up by building
them from scratch. This is much easier than actual scratch building
because you have the kit part to compare to your new piece.
Many of the kit parts are easy to replace. The ones that are a
bigger challenge are the very large parts with long bends and things
like the wing spars that also have solid rivets to deal with.
You can order replacement parts from ZAC. You can also order
replacement materials from them or any other source that has the
right stuff. In the case of 6061-T6 sheet metal and extrusions there
are many sources. This material is very common in the market place
for use in all sorts of stuff - not just aircraft or mil. spec.
use. At some stage, ZAC will include some spare materials in your
kit box too.
The only advice I can offer is to do what ever you are comfortable
with. If you don't like your results and feel uncomfortable then
order replacement parts. The nicest part of all metal construction
is you can undo just about anything and keep working on it until you
are satisfied. It is you, the builder, who must take responsibility
for all the parts and the final construction.
Have fun,
Paul

just installed the aileron and found out that the rod from the bellcrank is to
long. I measured and checked eveything again and still cannot see my mistake and
there is no eye end to eye end measurment on the plans.
Can someone who has this rod handy please measure from the enter of one eye end

and yes when I look through the eye ends I have the steel rod ends in deep enough.

Subject: | Length of Aileron Rod? |
Chris,
No mistake, the rod is too long, on purpose I guess. I screwed the rod into the
bellcrank connector, held the aileron at neutral, placed the other end of the
rod along side the aileron connector and "eyeballed" the location for the cut.
I cut it a little long and trimmed it later for a proper fit. Since it is
a stainless steel rod, it will not be easy to cut and you will probably have
to dress the end threads to get it to screw into the connector. It's really not
too hard a job. Good luck!

Ernie-
We're all "Hybrid" builders. I haven't seen a completed project yet
that didn't include some embellishment to the basic plans. The way I
figure it, if you're making a non-structural mod ( Fairings, light
installation, etc.) go for it.
On the other hand, if you're considering making a flying surface
larger or smaller or modifying the gear, list advice isn't for you- you
should talk to Zenith.
As far as I know, you only incur a weight penalty if you go to the
next size larger stock. DON'T THROW THINGS- I SAID "AS FAR AS I KNOW"!
The big problem with using .125 stock for the horn is, it's hard to
bend, and you're not allowed to heat it with a torch. There are a lot of
things you're not allowed to do when building an airplane that are
perfectly legal for tractors!

<I am looking for some sort of CG range data for the <slatless wing-if
anybody has or knows would appreciate it
We have three slatless 701's at our airfield, and some experience with
adjusting CofG.
Hans' (912S) weighs in at 503kg (1107lb) at 26% m.a.c., loaded for
travel, with 82kg (180lb) pilot, 95litres (25gal) fuel in wing tanks,
two jerrycans of fuel 28kg (62lb) on pax seat, and 20kg (44lb) baggage.
Gene's (912) weighs in at 496kg (1091lb) at 25% m.a.c., loaded the same
as above.
Hans' and Gene's were actually weighed in that loaded condition on
professional scales.
Phil's (912) was weighed empty, and the loaded conditions calculated.
It weighed in empty at 283kg (623lb) at 22% m.a.c. This a/c has the
original 40litre (10.6gal) fuel tank forward in the cowl, and 40litre
(10.6gal) in the wings. Calculating the most forward CofG, (single
pilot 82kg and full forward fuel), gives CofG at 21% m.a.c. Calculating
full load CofG, (full fuel (80litres), pilot 82kg, pax 82kg, no
baggage), gives 502kg (1109lb) at 28% m.a.c. Due to that forward fuel
tank we had to put the battery right back in the tail to get the most
forward CofG to 21%, which is still quite far forward...... This a/c
has a history, in that when we bought it in a crashed condition the
battery was forward of the firewall, so what was the actual CofG! The
crash occurred when a ferry pilot, unfamiliar with 701's, tried to take
off from a short strip and then tried to abort too late when the
aircraft didn't want to rotate easily........ More detail on that in a
separate post - there's lessons there I think.
Of the three aircraft, Phil's balances the best with a CofG at about 27%
(pilot + pax + part fuel), Hans' balances well at 26%, and Gene's feels
just a little bit nose heavy at 25%. This is testing the balance in
glide, and the ability to flare comfortably at idle power. The next
testing we will be doing is to adjust Gene's to 27% to see if it feels
better there......
Wishing fair skies and tailwinds all year.

Hi John,
Do look over my website Canopy page. It is progressive and pictures the
evolution of completing it without
any words. I'd not paint until the canopy sides and forward arm covers
are ready as well. Tape your canopy down after
you've trimmed front and back to within a quarter inch from the skins
with the latches locked. Trim the sides after getting position
for the front and rear edges where they should be. I don't recommend
the front edge flashing as it's unnecessary if you trim close.
Don't get in any hurry as this will lead to mistakes. If you use
painter's tape to secure the canopy and common reference points drawn
on the tubes and the canopy, you' ll get consistent position from which
to make the cuts around the latch lever. Ink marker works.
Doing the canopy is a bit of artwork in measuring and cutting, but it
can be done by completing each segment of
the thing just one problem at a time.
Good luck,
Regards,

Robin,
Putting the fuselage down 12 to 18 inches will help with fitting out,
deciding clearances front edge to forward top skin and also for
connecting cylinders several times. Just measure the length from the
pivot point to 6 inches behind the B2 bow and set an angle of 80 degrees
from the pivot. See link to get an idea of what is,

Subject: | What Size Brass Safety Wire? |
When I installed my turnbuckles, I used someone else's safety wire. Now I
don't know what size to use to replace the turnbuckles after my annual insp
ection (next month). Does anyone know the correct size wire to safety the
turnbuckles? Thanks in advance.Phil Maxson601XL/CorvairNorthwest New Jerse

Per AC43.13-1B/2A "Acceptable Methods, Techniques, and Practices
AIRCRAFT INSPECTION, REPAIR & ALTERATIONS" in Table 7-8 "Turnbuckle
safetying guide" for 1/8 cable using Single Wrap use .040 Stainless
steel, Monel or K Monel or 0.057 min Copper, Brass. For Double wrap use
0.040 Copper,Brass (Galvanized or tinned steel, or soft iron wires are
also acceptable for Copper,Brass).All material should be annealed
condition.I highly recommend all builders procure a copy of the above
AC, I believe you will find it invaluable. It also shows the proper
way to single or double wrap safetying of turnbuckles.Tony Graziano
