Aircraft modeling has undergone significant
changes over the decades - both in technology and preferences. Magazines like American Aircraft Modeler, and American
Modeler before that, were the best venues for capturing snapshots of the status quo of the day. Still, many things never
change, so much of the old content is relevant to today's modeler.

200 MPH Volkswagen?
"Witt's V," like all his other racers, is faster than it looks. The simple lines are very efficient.
by Don Berliner and Bob Pauley
Some people just don't know when to quit. Like, for instance, Steve Wittman.
In the Spring of 1974, he'll be 70 years old. That's the time to sit back and reflect on more than 40 glorious
years of designing and building and flying some of the most exciting airplanes the world has ever seen; and on a lifetime
of showing the aviation world that there's a simpler, cheaper way of doing what other people insist on doing in complicated,
expensive ways. The spring-steel landing gear on the past 25 years' worth of fixed-gear Cessnas is one of Steve's clever
inventions. And a 125 hp two-place lightplane that cruises 50 percent faster than anything the industry has been able
to create? Well, his Tailwind does that with ease.
The Grand Old Man of Air Racing, Steve Wittman, looks forward to his 70th birthday and to
his first race in his Formula Vee racer.
Steve has had more harrowing experiences than most people can imagine. Like the time he was shot down while flying over
the Great Smokey Mountains and came out of it without a scratch. Or like the time, many years ago, when his engine quit
during a race and he landed on top of an Army bomber! Or the time he threw a prop blade while flying out over the middle
of Lake Michigan in his Tailwind-and glided back to his home field to land with an ice-cold engine.
sampling would be enough for anyone person, no matter how talented. But small, fast airplanes have been so much a part
of Steve Wittman's life, that neither age nor retirement could interrupt their romance. In fact, the extra spare time
afforded by retirement was just what Steve needed to enable him to start on some of the projects he'd been thinking
about for years.
Priority Number One went to a Volkswagen-powered sport racer for the new Formula Vee racing
class. The idea of building an airplane suited not only for racing, but also for low-cost sport flying really appealed
to Steve. And using a car engine in a homebuilt airplane was another idea with all sorts of potential, especially in
view of the steadily rising cost of the few small aircraft engines still available.
Steve had been in on the
beginnings of Formula Vee, back in March of 1964. The men planning an "aerial Olympics" for Palm Springs, Caif., wanted
a new class of homebuilt racers, and so Formula Vee was created (it was then the 95 cu. in. class) from an idea then
being worked on in England. The Palm Springs extravaganza was pretty much of a flop. Formula Vee was more so. There
wasn't a single airplane off the drawing board, let alone in the air.
The shortest route to speed is aerodynamic cleanliness. Witt's Vee has no more than the absolute
minimum frontal area and a very thin wing.
As the 1960s dragged on, sport racing type people went in the direction of the established Sport Biplane Class and Formula
I. These classes were growing well, but not so well that a lot of people and money could be siphoned off to
a new class without risking serious damage to the old ones. Formula Vee just sat there, whimpering.
in 1969, the first pieces of metal were cut. And even though there was no immediate prospect of a race, Steve s V out
for public view during the first EAA Fly-In to be held at Wittman Field, Oshkosh, Wisconsin. The 1970 Fly-In was held
at the field he had managed from 1930 until the late 60s; his home and hangar/shop are just across the runway.
The Instrument panel of Witt's Vee: Simple and lightweight. (From Left): Manifold pressure, oil pressure, G-meter,
airspeed, altitude, oil temperature.
The critical area where the wing meets the fuselage. The square-sided cowling is easier to build and just as clean
as one with flowing lines.
Landing gear struts are of titanium. Wheel pants will come later.
Classic Wittman lines: Boxy. with a strange combination of curves and points. But it's the first one across the
finish line that wins ... not the prettiest.
A long prop extension permits the sharpest nose of any VW-powered engine.
The airplane so eagerly awaited by homebuilders and race fans alike must have been something of a disappointment. It
was an oversized Formula I: angular, hump-backed and painted a garish green with yellow wings. It wasn't particularly
sleek. It certainly wasn't very pretty. And it didn't look very fast.
But it was by Wittman. His Tailwind fits
the above description more or less, and it's darned fast. Sporting aviation people have long since learned not to scoff
at anything from the wise old hands of Steve Wittman, and so they looked very carefully.
What they saw was the
shape of things to come-just like his Buster had shown them in the first Formula I race at Cleveland in 1947. For the
first decade of Midget Racing, practically everyone who had started off in some other direction, eventually came around
to Wittman's way of doing things. That was because Steve's homely little racers won most of the races in those days.
He won races because his airplanes were clean and light and simple. They got off fast and they got around the
turns with a minimum loss of speed, and they rarely failed to finish a race due to mechanical problems. This philosophy
has worked for Wittman for many years, and he sees no reason to change it. The new little VW machine was simply more
of the same.
With an empty weight of 435 lb., and the required minimum wing area of 75 sq. ft., he came up with
a wing loading, at racing weight, of about 8 lb. per sq. ft. This means such tight pylon turns that not even the most
nimble of Formula Is could hope to keep up with him around the turns. Several tried it in an exhibition race and watched
him leave them flat at the corners.
One way he kept the weight down was to use thin wires to brace the wing,
so he could get by with a much lighter wing spar (and faster airfoil) than airplanes having cantilever wings. A bonus
advantage of this -is the elimination of the spar sticking through the cockpit - any extra room for the pilot can be
a blessing on cross-country flights.
One of the big problems with VW-powered airplanes has been the high drag
of the blunt nose, for the famous German car engine is not meant to be tucked into a streamlined airplane cowling. Steve
turned the engine around (so it runs the right way and he can use standard propellers), and built a special housing
for a long extension prop shaft. With the widest part of the engine far behind the prop, a super-sleek cowl could then
Construction is basically conventional. The wings are of spruce with plywood covering. The fuselage
and tail are built up of chrome-molybdenum steel tubing and covered with fabric. Only the landing gear is different,
with all struts having been machined from titanium stock-light but rather springy.
Even after the airplane flew
in late 1970, development moved slowly, for there were no other Formula Vees in the air, hence no races coming up. Steve
wasn't satisfied with the center of gravity of his little bird, and made a major change in the location of the wing.
The engine, too, gave problems. for he was exploring unknown territory in the use of a VW engine in a high performance
airplane. Prior to his racer, VW-powered lightplanes had been operating in the 100-130 mph range. He passed by this
without a pause. and then 150 mph, and then 170 mph.
As he slowly built up hours on his new No. I, he became
more and more pleased with its handling characteristics and speed range, and this was what he wanted. Soon, spectators
at fly-ins and airshows were witnessing aerobatics displays by Wittman and his little Vee:
Rolls on top of loops,
snap rolls, and even the rarely seen falling leaf. From a minimum speed of around 45 mph right on up to the top speed
of at least 175 mph, it flew without a bad habit.
Its first time on a race course came, appropriately enough,
at Cleveland, during the 1971 Formula I races at Lake¬front Airport. To get there. Steve hopped into his flying Volkswagen
and covered the 500 miles from Oshkosh in just three hours flying time. His few laps were strictly an exhibition. but
he showed a lot of people that his low-powered sport plane could not only fly cross-country in fine style, but also
wrap itself around a tight pylon course like a true racer.
By now. a second Formula Vee design had flown and
was attracting a lot of attention. Young John Monnett's Sonerai had a cantilever folding wing with a thicker airfoil,
but otherwise resembled Steve's Vee in general arrangement. Monnett was eager to get the class going, and so immediately
began selling plans with enthusiasm-and considerable success. Wittman preferred to hold back
until he was 100
percent satisfied with the design, though a few pushy friends were able to badger him into releasing some drawings so
they could begin building their own.
The months dragged on, however, and still there wasn't a sign of a race,
mainly because there were just the two Formula Vee airplanes-and what kind of a race can you have with two planes? Dozens
were being built, but race organizers want some kind of assurance that at least a half dozen will show up, before they'll
agree to put up prize money.
Lacking races for h is airplane, Wittman continued to do what he could to stimulate
interest in the new class by flying airshows and by showing the folks what his machine will do-such as fly it across
the Rocky Mountains to Reno in 1972 to see the Air Races. In classic Wittman style, he simply climbed in and took ott.
While crossing the highest mountains short of the Pacific Coast, he climbed as high as 16,000 ft. and reported the airplane
handled "just fine" up there.
time a few more thousand people see Steve Wittman and his neat little VW racer perform, a couple more think seriously
about building their own. He has now sold several dozen sets of plans, while Monnett must have topped the 100 mark.
By the summer of 1974, a half dozen or more should be flying, and the first race in the history of Formula Vee could
be upon us.
In fact, the Great Miami Air Races, scheduled for January 18-20, 1974, has tentatively included a
Formula Vee in its program. It may come off, and then again it may not. But each step brings Formula Vee closer to reality.
And if the exact date of the first race is far from certain, one thing can be counted on: Steve Wittman will be the
odds-on favorite to win that first race, wherever it is.
There's a very good reason for that "No.1" on the side
of Witt's V.
AMA Plans Service offers a full-size version of
many of the plans show here at a very reasonable cost. They will scale the plans any size for you.
It is always best to buy printed plans because my scanner
versions often have distortions that can cause parts to fit poorly. Purchasing plans also help to
support the operation of the Academy of Model
Aeronautics - the #1 advocate for model aviation throughout the world. If the AMA no longer has this plan on file, I
will be glad to send you my higher resolution version.
