 The Vision is a plans build plane from the USA state IL
 Pro-Composites Scott VanderVeen is the owner of the company.

 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
 McCandless  in Perth

 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.

 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

 alternative to kit build planes.

 Cruise Speed ...    140 mph     140 mph Range ......... .....   600
 miles     500 miles Engine.........     Corvair 2700     VW 2180
 Power.......... ''    100 HP  .......   70 HP Fuel Consumption... 5.5
 gph     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 :-)

--------------------------------------------------------------

Ops forgot the pictures. Here they are. Jim Hall's dentist Leo Windecker saw the fiberglass
chassis Chaparrals and built the first fiberglass composite light aircraft in the world in Midland Texas.
Chaparral of course was located in Midland.

 https://en.wikipedia.org/wiki/Windecker_Industries

I had nothing to do with the fiberglass chassis design as the stiffness to weight
ratio was not as good as sheet aluminum. Later chaparrals were sheet
aluminum monocoques much like Cessna's.
