Hi Paul, we have had a couple of Visions built at Serpentine. One
had a Subaru engine, reg VH WRX, and flew OK, though the airframe was
a bit heavy. The other is still under construction and has 6 inches
added to the cabin height as the builder is about 6’6” tall. Rs,

Dave: You don't have contact with the builders or possible contact
details of the flyable version of the Vision.?The builders group is
not a very active and only a small group sharing there experience.
Will contact you in private for the details. Forgive me Paul for
reaching out on this group ,as to get hold of our family of
builders. Much appreciated.
Le Roux Breytenbach
The Internet and this newsletter never seizes to amaze me. Le Roux
and Dave are just across the Indian ocean from each other. And I am
on the exact opposite side of the globe :-)
You guys can use the newsletter. I am sure there may be one or two
more Visions being built on here.

Hi Paul and Le Roux, Nice Depiction of the Oceans. Give me a day or
two and maybe I can get some pics. The guy who built the flyer has
passed away, but the airplane is still around. Rs,

I have Vision plans. But I've never had the time to actually build
it.

Are the wings hot wired foam David?

Back in 2011 Pierre Swanepoel from S. Afica (I think) was building a 13b
powered vision. Here are some 3D's and pictures
Paul Lamar
Nope, sheet that is cut to shape, then glassed. I did the project
they sold the VHS tape called the "Totally Useless Box", it is the
primer to get you used to the techniques in building the Vision.
David Mikesell
This is great. This looks like the cheapest way of getting into
aviation. With or without a pilots license All you need to do is
solo. While you are building this airplane will locally acquired
materials. I hope blue Styrofoam is available all over the world.
Other than the gear box the 13B rotary is near free.
Paul Lamar
Yes the Vision Ex what i am building is the only way for me to get
into owning my own plane at a affordable price.The Vision EX has a
longer wingspan that is more forgiven in weight if you are building
on the heavy side of the composite techniques.Paul is right you
source your building material according to the specs ,locally at a
composites shop."Pay as you go " at your own time and build in your
garage at your own pace.In ZA you apply for a builders number at the
CAA (Civil Aviation Authority) then a "approved person" vissit you
and sign and stamped your building logs.
Paul i have got hold of Pierre Swanepoel Vision #338 project and
the fuselage will be finished in this year.He is retired now That is
how i came to the rotary newsletter as the emails that you send and
i has found in his files between the plans.What a pleasure to build
, the plans is simple , and no "rocket science" to do basic lay ups
and vacuum bagging with carbon fiber or glass.
Steve Rahm the designer of the Vision was a real plane builder and
that reflects in the design and plans.Short sweat and simple in your
garage with no special tools. The main reason why there is not many
completed is you must sacrifice building hours and "sweat capital".I
know there is a builders in the newsletter that builds Cozy"s and
Tango's and Glassair's and i am inspired by you Dave M you will make
my day in finding a Vision "down under" in Ausieland
Le Roux Breytenbach
I assume blue Styrofoam is available down there SF. Is that correct?
Other core material could be used . End grain balsa wood is an
excellent core material. For the thicker bulkheads.
Wood door skin Luan plywood could be used for thin wing skins. It is
a very light weight wood that is about 1/8th of an inch thick.
It is low cost in the US. I noticed a distinct lack of plywood in the
hardware stores when I was in Oz. Perhaps I am looking in the wrong
stores.
One might save some money at the expense of a little extra empty
weight.
The rotary can make up for that with a lot more power.
Paul Lamar
We use the Gurrit PVC foam cores yellow and green colour in sandwich
construction. Yellow is 3.7 Lb/ft3 nominal density and Green 5
Lb/ft3 Only 2 thickness sizes the 1/4 inch and 1/2 inch for all the
building needs. Styrofoam is also used on some parts in building.
The glass lay ups to sandwich the core material, is Uni directional
or bi directional glass or carbon fiber or both according to the
plans.
Very light and strong.
The Vision has a "wet wing" and the fuel is stored in fuel cells
forward of the spar.Therefore no Styrofoam core material in wings.
The wings have 1/4 inch pvc foam ribs with flanges sandwich between
280 gsm twill weave glass

Cruise Speed ... 140 mph 140 mph
Range ......... ..... 600 miles 500 miles
Engine......... Corvair 2700 VW 2180
Fuel Consumption...
100 HP ....... 5.5 gph
70 HP ..........4.5 gph
There is some bull shit going on here.
5.5 GPH is 35 pounds per hour and that is about 75 HP with a BSFC
of .45.
It is not likely to go 140 MPH on 75 HP
In fact it is unlikely to go 140 with 100 HP.
In fact the 140 cubic inch Corvair is unlikely to put anywhere near
100 HP direct drive.
Stock at 4400 RPM was 80 HP.
My guess is it weighs about 200 pounds with out a gear box.

The VW specs are even more unlikely.

Paul and group, We get Polyurethane Foam (green) at 2# per cubic
foot. Fuel will not affect it,

What does it cost Virg?
Back about 1965 I did some research on panel stiffness. Panel
stiffness is essential for monocoque structures. Monocoque aircraft
structures. were invented in WW 1 by the German Albatros aircraft
industry.
I compared fiberglass sandwiches with sheet aluminum other
candidates for race car bodies by measuring the deflection.
PVC 1/4 inch foam with one layer of 4 oz fiberglass and epoxy resin
won. I have the data I wrote down in 1966 somewhere. When I find it I
will post a copy.
The Chaparral 2F was the first race car to use this body material.
The body was so light after it was painted it weighed twice as much
:-)
Here are pictures of the 2F. This was long before Rutan :-) The
cooling was done right too :-)
Paul Lamar
In the 70's, it was $0.25 per board foot. You
figure inflation,
