Vans RV-7

Van’s RV7A

The RV-7 is the pre-punched fuselage of the RV-9 and the pre-punched wings and tail of the RV-8 married together. It comes in tail wheel or nosewheel, and sliding or tilt up canopy. The RV-7/7A replaced the RV-6/6A.
About 70% of our customers prefer side by side seating and the RV-7/7A has a roomy cockpit that will easily accept two 6’ + adults with sufficient leg, head and elbow room to stay comfortable for three to four hours at a time. The seating arrangement puts both occupants on an equal footing – standard dual controls and optional dual brakes give either occupant full control with equal visibility.
The RV-7/7A retains all the traditional RV virtues. It is an all-around sport airplane, with excellent cross-country capability, fine aerobatic qualities and superior handling. A typical RV-7 can hold two FAA standard pilots, 100 lbs. of baggage and full tanks: 42 gallons. At the aerobatic gross weight of 1600 lbs., the RV-7/7A complies with the +6/-3G standards of the FAA’s Aerobatic Category and can still carry two people, making it possible for a new pilot to get aerobatic instruction before he or she starts rolling and looping.
Both sliding and tip-up canopies are available. Both may be opened for taxi ventilation.

RV-7A

All RVs are capable of very short take-offs and landings and the RV-7/7A is no exception. Equipped with any Lycoming engine between 150 and 200 hp, and either a fixed-pitch or constant-speed propeller, it will leave the ground quickly and climb at impressive rates. The rugged fixed steel landing gear (tailwheel or tri-gear) makes it possible to operate from almost any airstrip, including grass or dirt.

Vans RV-6 / Aeronautical Industrial Engineering and Project Management Company Ltd. / AIEP Air Beetle / T18

RV-6

Soon after the RV-4 proved that a two seat RV was practical, prospective customers began asking for a side-by-side RV.
When the demand became too big to ignore, Van went back to the drafting board. Using what he’d learned from the RV-3 and RV-4, he designed the RV-6.
He made it 43 inches wide and gave it a baggage compartment behind the seats. The wing on the RV-4 worked so well that there was no point in changing it, so he didn’t. The canopy was a forward opening bubble that closed almost seamlessly and the fuel capacity was increased.
The RV-6 made its first flight in 1985. When all the flight testing was done, it was only three miles per hour slower than the RV-4.
One limit to RV sales had always been the fact that they were all tailwheel airplanes. Installing a nose wheel solved the problem. The RV-6A featured a very simple tricycle gear, with steel rod main gear legs and a free castoring nosewheel. The nosegear leg was supported by the steel engine mount and required no complicated steering mechanisms or shock absorbers. The modification resulted in very little weight gain and almost negligible performance loss.
After the RV-6A was flying, Van’s designed a sliding canopy option on both the RV-6 and RV-6A.

Kits were priced at $11,810-12,565, and a quick-build kit at $19,320-19,995.

Eustace Bowhay, of Salmon Arm, BC, is a pilot with vast experience in both land and water aircraft. He carefully researched the matter and decided that the RV-6 had the potential to be an excellent floatplane. After consulting engineers, he designed a float installation and submitted it to the Canadian authorities for engineering approval. The Canadian Ministry of Transport determined that the RV-6 was strong enough, without modification, to handle the added stresses and loads imposed by flying off water. Cruise speeds, with the 180 hp Lycoming and constant speed prop, were 150 statue miles per hour. The water handling characteristics were excellent and the airplane was easy to land and taxi on land or water.
After flying the airplane on both wheels and straight floats for two years, Eustace and Jim decided they could have the best of both worlds, and installed amphibious floats. These worked just as well.
In 2005, Eustace, then over 80, decided that it was time to step out of the cockpit. C-GHAY was converted back to wheels and sold. Eustace died in 2006

Aeronautical Industrial Engineering And Project Management Company Ltd. / AIEP, in Nigeria was established 1979 to assemble kits of the Van’s RV-6A, known locally as Air Beetle and used by the Nigerian Air Force as the T18 trainer.

The RV 6s normal limit of plus or minus 6g, fully aerobatic in the sports category. The carburetted 160 hp Lycoming 0 320H2AD. Empty weight is 1010 lbs and the 1600 lb MAUW and full fuel of 144 litres.
Climb speed of 90 kts brings only about 2350 rpm, with around 1200 fpm indicated. This RV 6 will climb at 1600 fpm at MAUW at its best angle speed of 65 kts. Cruise at 75 percent power is slightly better than 150 kts, not much slower than full power.

Vans RV-5 Swinger

The RV-5 Swinger was a very small, metal single-seater cabin, high-wing monoplane, designed by Van and built by a group of friends from a local EAA chapter. First flown in May 1976, it flew quite successfully with a small two-stroke engine, only one was ever built. It is still in Van’s hangar and one of Van’s engineers recently surveyed it with an eye toward restoration…it may fly again.

Vans RV-4

Of the Van’s RV series, the RV-4 was by far the most popular. The two-seat RV-4 was developed from the company’s single-seat RV-3 and the philosophy behind the design of the RV-4 was to have a two-seat aircraft that handled as close as possible to the single-seat RV-3. When the RV-4 first flew in August, 1979, the result was a tandem seating arrangement, which allowed the frontal area to be kept to a minimum, and gave it a top speed of only about 8 knots less than the RV-3. Further, its handling characteristics are said to be “virtually identical” a result that surprised even the Oregon-based kit manufacturer.

The RV-4 is an aerobatic, two-place tandem, low wing monoplane of aluminum monocoque (stressed skin) construction. The propeller is a Cassidy Pacesetter 200 wood prop, which experience with the RV-3 has proven to have excellent overall performance. The engine used was a new Lycoming 0-320. Fuel is carried in two integral wing leading edge tanks. The standard canopy is a single-piece bubble which opens to the side.
It is flown from the front seat only, but the kit includes a stick for the rear-seater. It is designed for engines of 150-160 horsepower, although engines as small as 125 hp and as large as 180 work well and are commonly installed.

The RV-4 is capable of “sport” aerobatics. It was reported that around 600 were flying worldwide and the kit price was $10,905.

Vans RV-3

The Stits SA-3A Playboy served as a catalyst for Richard VanGrunsven, who, after modifying and improving the Playboy in 1965 (and calling it an RV-1), was further inspired to build an airplane of his own design — the RV-3.

Vans RV-3 Article

Richard VanGrunsven’s all-metal, single seat monoplane won the “Best Aerodynamic Detailing” award at the 1972 EAA Fly-in. The wings are built around a single I-beam spar and a lighter rear spar. The fuselage and tail unit are built of light alloy, and the engine is covered with a fiberglass cowling. The landing gear is the nonretractable tailwheel type with Cleveland brakes and fiberglass wheel fairings.

Feb 74

New sales of the RV-3 were suspended in 1996. However, in response to popular demand, the RV-3B with a new wing spar design is now back on the market. The empennage, fuselage, and finishing kits are essentially unchanged, however, the wing kits are new, and are available in two types: new and retro-fit. Builders also will have a choice between standard and QuickBuild wings, regardless if for a new project or retrofitting to an existing plane.

The difference between new and retro-fit spars is that some holes are left un-drilled in the retro-fit version so they may be matched to holes in the existing structure. Retro-fitting will mean removing the current fuselage center section and replacing it with the new one. While this may sound like major surgery, it is actually easier than trying to drill a spar accurately to a center section in an existing airplane.
The new RV-3B spars use four-piece construction, are gold anodized, and come completely assembled. New RV-3B wings have standard 15 gallon per side wing tanks, attached to the spar with screws and bolts so they may be removed for repair without taking a wing off the fuselage. Standard kit wing skins are not pre-punched. Bellcranks and tiedowns are now simple units that bolt on to holes already in the spar.
The RV-3B QuickBuild wings are similar in form to the RV-8/8A QuickBuild wings. They arrive with flaps and ailerons complete, tanks sealed and tested, leaving the builder only to add aileron brackets, flap braces, wing tips, and one outboard skin to complete the wing.
NOTICE: In order to operate RV-3/3A aircraft with pre-RV-3B wing designs in the aerobatic category, the owner must either complete appropriate spar Change Notices (materials provided at no charge) or purchase new wing kits. Until implementation of the appropriate spar Change Notice, kit/aircraft owners should comply with Van’s Aircraft’s previously published March 1996 flight recommendations:
“RECOMMENDATION: Until the spar modification is performed, we recommend that the RV-3 pilots immediately limit their flight G loads to a maximum 4.4 G’s; utility category. Based on our test results of an ultimate load of 7.3 G’s, a 50% over-strength margin would permit a flight limit load of 4.9 G’s at a gross weight of 1050 lbs. Since the 4.9 G’s is below the 6 G specification for the aerobatic category, no aerobatic maneuvers should be performed. Dropping back farther to utility category flight will offer an additional margin of safety.”
A logbook entry should be made prohibiting aerobatics until one of the Change Notice spar modifications is accomplished

More than 3,300 RVs were reportedly completed and flying by mid-2003.

Vans RV-1

One Stits SA-3A Playboy builders eventually sold his project to a young aviator who rebuilt the wing, getting rid of the struts and converting it from a fabric covered wooden frame to an aluminum wing in 1965 (and calling it an RV-1). The rebuilder was Dick VanGrunsven and his first airplane has been rebuilt and will be donated to the EAA museum this summer.

VanGrunsven was further inspired to build an airplane of his own design — the RV-3.

Richard (Van) Van Grunsven’s Van’s Aircraft, Inc. began in 1973 with partial kits for the RV-3. These were manufactured by Van himself, working in a small shop behind his house in Reedville, Oregon. Later the company moved to North Plains, Oregon, a small town about 25 miles west of Portland. After twenty years and several expansions, Van’s had exhausted the available opportunities in North Plains, so in 2000 the company moved to a new 60,000 square foot facility on the Aurora, Oregon airport. The company employed 70 people (and hundreds more in sub-contract roles) and keeps them busy producing several hundred complete aircraft kits a year and shipping them all over the world.
The RV-3’s performance gained an enthusiastic following, and naturally, many pilots wanted to share the experience with a friend. Van resisted for a while, reasoning that a bigger, heavier airplane just couldn’t perform as well as a light single-seater, but eventually he recognized the depth of the demand and began developing a two-place airplane. Tandem seating was chosen for the RV-4 because of the lower drag, superior centerline visibility, lighter weight, and overall fighter-like sportiness. It was a combination well suited to the market it entered in 1981. With performance nearly that of the RV-3 and an extra seat as well, the RV-4 became an immediate favorite and soon surpassed the RV-3 in popularity.
In the early to mid 1980s, the homebuilt market began to shift toward efficient touring, rather than pure sport airplanes. In response, Van’s developed the side-by-side RV-6. Careful design and attention to aerodynamic details resulted in a new airplane that retained the delightful handling and short field qualities of the RV-4, and despite the wider fuselage, had a top speed only 3 mph less. The trigear RV-6A was developed from the RV-6 to better fill the needs of the modern pilot. The addition of the nosewheel reduces the top speed only 2 mph.
In 1995, Van’s revisited the tandem concept and came up with the RV-8, a new design incorporating improvements learned from years of experience with the RV-4 and RV-6/6A. With a wider cockpit than the RV-4, two baggage compartments and increased instrument panel space, the RV-8 offers greater cross-country comfort without compromising the fighter-like sportiness of centerline seating. The RV-8 was designed to handle engines of 150-200 hp, and with the 200 hp IO-360 Lycoming, it sustains cruise speeds of 212 mph. Top speed is 222 mph. The RV-8A made its first flight in April 1998 and kits were available soon after.

The RV-9A, a side-by-side tricycle-gear design, was first flown in December 1997. A completely new wing with a higher aspect ratio and new airfoil gave excellent low speed flying qualities and very efficient cruise. Similar in size and weight to the RV-6, it cruises at about the same speeds, but stalls several miles per hour slower. This wing permits the use of lower-powered engines, providing an alternative for those who don’t feel the need for a “bigger, faster, more powerful” airplane. Somewhat later, the RV-9 tailwheel version was developed.
In the spring of 2001 the 2-seat side by side RV-7/7A was introduced, replacing the RV-6/6A. The RV-7/7A has slightly more leg and headroom than the RV-6/6A, carries more fuel, and has a higher allowable gross weight. It will accept all 4-cylinder Lycoming engines from the 150 hp O-320 to the 200 hp IO-360. The kit incorporates all of the advanced technology that Van’s learned designing and producing the RV-8/8A and the RV-9/9A.
In 2003, Van’s ventured into a whole new world and offered the RV-10, our first four-place airplane. Designed as a true four-person airplane (the ability to carry four people is different than having four seats) the RV-10 will carry four full-sized adults, sixty gallons of fuel and baggage. Speeds and performance are comparable to the two seat RVs, and better than most four-place production airplanes.
In 2005, about 4,000 RV kits (an average of almost 130 per year for the history of the company) have been completed and flown, and thousands more are under construction. Completion rates have exceeded one per day for the last few years. RVs are flying in at least 26 different countries and are under construction in more than fifty.

The RV-2 was a wooden flying-wing sailplane. Van started construction in the early 70s but the airplane was never finished or flown. Parts of it still hang on his hangar wall. The RV-5 was a very small metal single-seater, designed by Van and built by a group of friends from a local EAA chapter. Although it flew quite successfully with a small two-stroke engine, only one was ever built. It is still in Van’s hangar and one of Van’s engineers recently surveyed it with an eye toward restoration…it may fly again.

Valentin Taifun

The Taifun two-seater motor glider was designed by Thomas Fischer and Dipl-lng Jorg B. Stieber for Valentin GmbH Gerateund Maschinenbau, makers of high-quality aircraft switches.

The Taifun is a cantilever low wing monoplane with a T-tail; the one-spar wings and ailerons are of glassfibre/foam sandwich construction, with all glassfibre flaps. The wings can be folded flat along the fuselage for easier hangar stowage, and Schempp-Hirth air brakes are fitted in their upper surfaces. The stressed skin fuselage is also a glassfibre/foam sandwich structure as are the fixed incidence tailplane and elevator. All versions have disc brakes on the main wheels, and the nosewheel of the 15E and 17E is steerable; the undercarriage of both these variants is fully enclosed when retracted. The pilots are seated side-by-side under the rear sliding canopy, with dual controls as standard. Engine is an 80hp Limbach L2000 EB ‘flat four’ driving a Hoffman HO-V62 three-position two bladed
propeller.

Construction of the prototype had begun in July 1979. The prototype, a Taifun 17E registered D-KONO, made its first flight late in February 1981, as the Valentin Taifun, when more than 25 had been ordered.

Four versions of the Taifun were to be produced: the Taifun 15S is the basic model with 15m span wings and a fixed tailwheel undercarriage, the Taifun 17S has the same undercarriage as the 15S and 17m span wings, the Taifun 15E has 15m span wings and a retractable nosewheel undercarriage, and the Taifun 17E has the same undercarriage as the 15E but has 17m span wings.
