A while back there was some discussion of drawings that were approved by
Chris for extending the wings by 16 inches or so for the 701. Does anyone
have a copy of those drawings?

George,
Here are the original drawings, I was told they were done by the MAN (
CH ) himself. They are not as sharp as regular plans, but hey,, they
look as though they were drawn on a napkin, on a counter top.
After seeing these, I decided to extend my wing the same distance, but
between the cabin, and the main strut attaching point, so that there is
no increase in the length, outboard of the strut.
Good luck

| Subject: | Re: 701 elevator trim option |
I did straighten the trailing edge of the elevator and that did help make the trim
more effective in holding the nose up on landing. I then added the vortex
generators which made the elevator trim still more effective but not quite enough
to maintain a 60 MPH approach speed with out some stick back pressure. If
I let the stick float with full up trim, throttle at idle it will maintain about
73MPH.
Going full throttle with full up trim can make for heavy forward stick pressure.
I have a manual activation of my trim so it is as fast as I can move the leaver.
The advice of a quick acting trim came from an Alaska bush pilot who said
one wants to have a trim that gets off quick as possible on a go around.
All said and done I wouldn't want to be without an elevator trim, it makes flying
so much more relaxing.

Looking those drawings the date in the corner is October of 1992 and the
plans reference the 701UL.
I wonder if these drawings will still hold for the increased gross of the
newer plans.

I have no engineering experience, or knowledge, so any comment on my
part would be purely hypothical. This is one of the reasons I will be
adding the extra length, between the cabin, and the outer, main, strut
attachment point. Since my wings are not as yet assembled, this
modification will be relatively easy to do. Sadly, for those who's
wings are assembled, this would not be an option.
I don't know of any other, or up to date drawings referencing a wing
extension.

Maybe I am being dense on this, what is the purpose of the increased wingspan?
My gut feeling would suggest it is to increase lift but the 701 already climbs
very well. Am I missing something?

Zed,
Actually I plan on making up my own spars.
To the 3110m regular spar, I will be adding an additional 550 for a
total of 3660, which is exactly the length of my 12' sheet. I also
purchased some longer spar caps, 3/4 x 3/4 x .125 and will have them go
all the way into the spar tip.

Zed,
Like yourself, I responded, and deleted your previous message a little
too quick, and misread question. I assumed you were making a reference
to the spars, and not the struts. As far as the struts go, I will be
making my own, and covering them with an airfoil in aluminum.
During a trip to PA last Fall, I dropped in to see Dillsburg Aero Parts,
and purchased full lengths of chrome molly tubing in every size from
1/4" to 2", so I should not have any problem in fabbing up my own
struts, along with the jury struts.

Hi Doug,
I don't think your question is sarcastic or snotty in the least. It's a
legitimate question, and deserves a response.
Over the years ( many years ) I have accumulated a few hundred hours in
my log book, flying mostly with the Cessna's and Pipers from the local
flying school. When I decided to build my own plane, STOL performance
was not one of my priorities, but I chose the 701 so I could fly flying
as slow as I could. I am not planning on installing any slats, and will
have a full compliment of VG's on the main wings, and underneath the
rear stabilizer.
Since most of my flying will either be done from long paved runways, or
water, I can live with the lost of a little STOL capability, in exchange
for some slower flying speed. The extended wing will further reduce the
wing loading, and the absence of slats will improve the fuel millage.
In case no one noticed, I turned 65 a few weeks ago, so all I want to do
now, is safely fly as slow as I can , and skim the tree tops.
Hope this gives you a little insight on the reason I decided to go this
way.
Fly safe Doug.
Best regards
Robert Pelland

No, I was just wonderig if you had the one-piece factory struts.
If you had,and extended the wings inboard of the standard attach points you'd have
a bit of a dihedral problem.
Not my project, but I'd give serious thought to building as CH drew it.....adding
inboard changes the angle of the struts, and might be a reason to re-calculate
the wing loading....and that may not be the proper terminology.
Possibly some other List member with a slide rule can offer advice.
Otherwise, enjoy pulling rivets.

| Subject: | Re: More Extended Wings |
Zed,
The reason I decided to extend it inboard, rather then at the wing tip,
is just for the safety factor. Once the modification is completed, I
will have the exact same wing surface area as the regular wing, outboard
of the struts. As for the dihedral, once the wings are installed, it
will be adjusted to the exact same angle, as a regular wing.
I also reinforced a few of the major parts that make up the wing, so my
guess is that the extended wing, will most certainly be stronger then
the basic 701 wing.
Here are just a few of the changes.
Spar web is cut in .032 rather then the .025
Spar caps are 3/4 x 3/4 x .125 radiused on the inside
Web and root doublers, have both been made in .040
All the covering top/bottom, is being done in .020 rather then the
required .016
There will be a slight weight penalty with the above, but the additional
surface area, will more then compensate for the extra weight.
There will however be some additional angle work to do to both the strut
attachment points, but nothing that would cause any stress to the parts
themselves, just a slightly different mounting angle.
If you search around the web, you will see that there are dozens of
701's that have had their the wings extended, and all of them are flying
with no ill effect, or anomalies what so ever.
During a phone call to Calibe at the factory a few weeks ago, I informed
him of my intentions to extend wing, and here was his response.
He said that it would not be a problem to build in an extension to the
701 wing, or I could just build it initially to the extended length.
Always happy to exchange a few ideas, and pull some rivets, which BTW is
what I will be doing this evening.
Regards
Robert Pelland

I am a little younger than you (9 months)
I think the question posed earlier was are you planning to add the 16
inches inboard of the slats.
Meaning will you be building a longer SPAR?
One response asked if you were using the Zenith spar or are you building
one from scratch.
The answer lies in the method of construction. Since the sketch was for
the tip end or outboard end it simply added an extender.
The tip end is not structurally attached.
Adding 16" Inboard or at the root can only be accomplished if you are
building from scratch.
There are structural issues that you need to be aware of if this is so
Happy Building and flying

Excellent point,
I have a drawing from CH that shows basically the same treatment on the
tip but the main structural change was lengthening the doubler at the
strut attach point and increasing it's thickness, just got a new
scanner so will try to send it in an hour or two if everything goes
right. The fellow that sent it to me was the original recipient from CH
and it was for the higher gross airplane.

Robert
I am a little younger than you (9 months)
Nine months makes you close enough to be in my club. :o) welcome
I think the question posed earlier was are you planning to add the 16
inches inboard of the slats.
I am a little confused about your use of the word " slats " . Should I
read that as being " struts " rather then your use of slats, if that is
the case, yes, inboard of the strut attachment on the wing
Meaning will you be building a longer SPAR?
I have already cut the spars out of .032 to a total length of 3660m
One response asked if you were using the Zenith spar or are you
building one from scratch.
I am riveting my own. I purchased a 3X from " Cleveland ", along with
their new 12" back rivet setter, and first impressions are very positive
The answer lies in the method of construction. Since the sketch was
for the tip end or outboard end it simply added an extender.
The tip end is not structurally attached.
That is one reason I am not inclined to go with anything that does not
add structurally to the wing. I also plan on extending my spar caps as
far into the spar tip as I can
Adding 16" Inboard or at the root can only be accomplished if you are
building from scratch.
Definitely from scratch. My disability pension dictate's it can't be
done otherwise
There are structural issues that you need to be aware of if this is so
Randall, as you can see, " This is so " so would you care to elaborate
on what additional issues I should know about. ?
I will speak to you later this evening, because I am going into my "
hanger " ( read that as being my basement ) to skin my stabilizer. This
is also something to which I added my own touch. For what it's worth,
the mods I have made to the stab, were done before the plans for the
750, were made available. Check attached pic for the two views

Hi Doug,
I don't think your question is sarcastic or snotty in the least. It's
a legitimate question, and deserves a response.
Over the years ( many years ) I have accumulated a few hundred hours
in my log book, flying mostly with the Cessna's and Pipers from the
local flying school. When I decided to build my own plane, STOL
performance was not one of my priorities, but I chose the 701 so I
could fly flying as slow as I could. I am not planning on installing any
slats, and will have a full compliment of VG's on the main wings, and
underneath the rear stabilizer.
Since most of my flying will either be done from long paved runways,
or water, I can live with the lost of a little STOL capability, in
exchange for some slower flying speed. The extended wing will further
reduce the wing loading, and the absence of slats will improve the fuel
millage. In case no one noticed, I turned 65 a few weeks ago, so all I
want to do now, is safely fly as slow as I can , and skim the tree tops.
Hope this gives you a little insight on the reason I decided to go
this way.
Fly safe Doug.
Best regards
Robert Pelland

Maybe I am being dense on this, what is the purpose of the increased
wingspan? My gut feeling would suggest it is to increase lift but the
701 already climbs very well. Am I missing something?
While this post might come accross a sarcastic or snotty, I mean
this in as sincere fashion as possible.

looking for resonable insurance for a potential completed kit purchase.
Anyone have any suggestions besides AIG?
