UP Red Tail

UP Redtail was an ordinary rogallo with a short keel. A 1977 hang glider for intermediate pilots.

The Redtail features a J-wire nose cambering device, deflexers and sail mounted cleats. It has adjustable centre of gravity bar mounting bracket. The airframe is made from 6061 T-6 aluminium tubing with spars 1.5in x 0.049 and sleeves 1 5/8in x 0.058. Sprcial Ultralite Products “saddles” are used at all tubing joints to distribute loading over tube surfaces.

Rigging cable is 304 3/32in 7×7 stainless steel. Flying wires are not adjustable. Landing wires are turnbuckle tensioned. All bolts, washers, and nuts are grade 7 aircraft. The nose plate, tangs, control bracket, and kingpost bracket are stainless steel. The sail is Howe & Bainbridge 3.8oz stabilised dacron. All sails come with centre tail portions red. There was a choice of 11 colours for the remaining portion of the sail. The sail has applied leading edges for minimum airfoil distortion. A swing seat was included or optional prone harness.

There was another version of this glider that had a two foot shorter keel and was called Super Redtail.

UP Dragonfly

Dragonfly I

The 1974 Dragonfly Mark I was the first flex-wing, finite tip glider to be put into production. Designed for advanced and competition, it can be soared in approximately half the wind velocity needed for a standard Rogallo. It has a low sink rate, tight turning ability, broad speed range, and has no tendency to drop a wing even when banked at more than 40 degrees.

Roy Haggard’s truncated-tip Dragonfly performed well at the January 1975 Nationals at Escape Countery and he and the design went to work for Ultralite Products.

An exclusive quick set-up design uses a double pivot centre box which eliminates attaching or detaching the cross spar and leadspar assemblies. I has an adjustable centre of gravity control bar mounting bracket.

The leading edge spars are made from 6061-T6 1.75in x .049 aluminium tubing. Keel and cross-spar are 1.5in x .049. Ultralite Products saddles are used at all tubing joints. Rigging cable is 304 3/32in 7×7 stainless steel. Cables for deflexers are 1/16in 7×7 stainless steel.

All hardware is grade 8 aircraft bolts, washers and nuts. Stainless steel nose plate, tangs, control bar and kingpost bracket are fitted.

The sail is Howe and Bainbridge 3.8oz stabilised dacron and there was a choice of colours. Leading edge pockets are fitted for minimum airfoil distortion. Special soaring windows for upward visibility was optional.

The control bar was 6061-T6 1in x .083 aluminium with epoxy coating, and a swing seat was included.

The Dragonfly II is similar to the Mark I except the sail is fully battened and has less billow. It features doube plane deflexers to tune the wing shape and prevent leading edge distortion at high speeds. The sink rate, glide ratio and speed (increased 30%) are all improved.

The leading edge spars are made from 6061-T6 1.75in x .049 aluminium tubing. Keel and crossbar are 1.5in x .049. The entire airframe is fabricated with stainless steel “telebush” units for strength. The Mark II has an adjustable centre of gravity control bar mounting bracket permitting 4in of total adjustment. An additional 5 lb could be saved by ordering the glider with 2024-T3 x .035 tubing.

Rigging cable is 304 3/32in 7×7 stainless steel. Cables for the deflexers are 3/32in 7×7 stainless steel. All hardware is grade 8 bolts, washers and nuts. Stainless steel nose plate, tangs, control bar and kingpost bracket are fitted.

The sail is Howe and Bainbridge 3.8oz stabilised dacron and there was a choice of colours. Leading edge pockets are fitted for minimum airfoil distortion. Special soaring windows for upward visibility was optional.

The 60in control bar is 6061-T6 1in x .083 aluminium with anodised finish. It could be ordered with prone or supine rigging or set up with ‘flip-flop’ wires for quick adjustment to either type of flying.

Pasadena California, 1970. Pete Brock finishes his studies at the Art Center, a world-renowned school of industrial design, as its youngest graduate ever. Brock soon discovers a new passion: hang gliding- probably the most radical sport imaginable in the early 70s. While there are several glider models on the market there is only one common theme – they are all extremely dangerous. This also holds true for Pete’s first design, the Brock Redtail.

However, when Pete Brock gets together with the young designer Roy Haggard, a new concept is born. The Dragonfly is the first tenable post-Rogallo glider and becomes the flagship of their newly founded company, Ultralight Products. A series of successful designs follow, including the Condor with its world record duration flight of 16 hours, 4 minutes in 1979.

Helping the company gain success quickly is Pete Brock’s logo design. The UP arrow achieves cult status from the beginning and for many pilots characterises the spirit of hang gliding and later paragliding. The logo and the brand’s positive image attract the interest of various investors over the company’s three-decade history. The first is in 1980, when Yuseke Yamazaki, a Japanese investor, lays the foundation for UP’s success in Asia.

The year 1980 also marks the introduction of Roy Haggard’s pioneering development, the UP Comet. The Comet’s outrigger-free construction concept was revolutionary. Jim Lee sets the world distance record at 268 km with a Comet in 1981, and eventually the UP Comet becomes one of the biggest-selling hang gliders of all time. Success breeds followers, and the Comet is a natural target for copying. In 1982 Airwave, UP’s representative in Europe, produces the Magic, which is nothing more than a modified Comet.

In the mid-80s Pete Brock and Roy Haggard retire from the everyday business. Ownership and location of the firm change in the following years. Through the continued influence of Yuseke Yamazaki, UP becomes UP International, a wholly owned subsidiary of a Japanese parent company, Isomura, Inc. Encouraged by the success of the hang gliding business, Isomura diversifies the UP brand into windsurfing, UL-flying and fashion. In Japan one can find the UP arrow on the UP-Sports clothing line, and on T-shirts, jackets and socks. Even today at Venice Beach in Los Angeles one can find rollerbladers leaning against the UP arrow logo as they take breaks on park benches donated by the local UP surf shop in the mid-80s.

The TRX, the first production series hang glider with carbon tube elements, is developed at the UP Soaring Center in Salt Lake City under the guidance of UP’s new designer, Terry Reynolds. Despite various technical innovations, the TRX remains the last successful UP hang glider for some time.

Though UP is a latecomer to paragliding, the company hits the mark in 1990 with the relatively unknown Korean designer Gin Seok Song. The Flash, developed by Gin in the U.S. together with test pilot Greg Smith, is revolutionary. The Flash is the first paraglider with a perfectly smooth leading edge and has more performance than anything else on the market. The glider dominates in competition and becomes a bestseller. Yet the Flash remains Gin’s only design for UP since he is coaxed to another paragliding newcomer, Edel, with a lucrative offer.

At this time, Claus Bichlmeier is UP’s importer for the German-speaking markets.

Ultralight Products Europe
1998: Altjoch 19 A, D-8243 kochel am See, GERMANY
By 1998 UP Delta had bought out aircraft manufacturer Thalhofer.

In 1992 Ernst Schneider establishes UP Europe in Sindelsdorf near Garmisch and all development and testing is carried out in Europe. Designer Rasso von Schlichtegroll, later co-founder of freeX, develops best-selling gliders like the Katana, the Vision and the tandem Pickup. Chief Test Pilot Ernst Strobl crowns his competition career in 1992 by winning the European Championship.

That same year Uli Wiesmeier wins the first Paragliding World Cup series on a Katana. In addition to his involvement in competition, Uli is responsible for UP’s public image. Uli’s advertising work, his eye for style in developing the Skywear line of clothing and his award-winning creativity in filmmaking all contribute greatly to ensuring that the UP thrives in paragliding. French UP pilot Richard Gallon wins the 1994 PWC. In 1995 the new World Champion Stephan Stiegler and top pilots like Peter Hensold, the Italian cross-country ace Eduard Taschler and Sebastian “Rambo” Bourquin become members of the UP team.

Motivated by UP’s success in paragliding, Ernst Schneider establishes a hang gliding department under the auspices of UP Europe. The original Salt Lake development team at the Soaring Center starts a separate company that eventually leads to the formation of Altair under the leadership of Dick Chainey and John Heiney. Bernd Weber, the manager of Thalhofer and co-founder of the rigid wing manufacturer A.I.R. takes charge of UP’s new hang gliding line. The Speed, UP’s first hang glider in nearly five years, is introduced in 1995, and the topless version, the Speed TL follows in 1997.

UP Europe Delta
1998: Salzstrasse 6, D-72589 Römerstein, GERMANY
In 1998 UP Europe was manufacturing the wings for the rigid wing Pegasus of Jurgen Lutz, having bought out aircraft manufacturer Thalhofer.

Ernst Schneider sells UP Europe, and the buyer is once again from Japan. The profitable entertainment group Daiichi Kosho is seeking to diversify from the Karaoke industry and is looking to the flying industry for an additional profit center. With the continually developed paragliders from Europe and their own paragliding schools domestically, “DK” quickly enjoys market leadership in Japan.

The Japanese invest substantially in UP Europe, where the workforce and the competition team are expanded. In 1997 half of the German League is flying UP’s new performance glider, the Escape. During this time, UP Europe relocates to offices north of Garmisch in Kochel am See, where up to 20 employees are working.

By this time, the paragliding boom is subsiding and high quality designs like those of the Escape, the Soul, and the Blues do not attain the market successes of their predecessors.

Daiichi Kosho and UP part ways in 1999. At the same time, Bernd Weber gives up the hang gliding part of the business. Of the several parties interested in the remaining paragliding business with the exceptional UP brand, the successful bidder is the Swede Christian Rönning. Flying since 1988, Christian is one of the pioneering paraglider pilots in Sweden. He also brings with him a wealth of experience gained as a management consultant to multinational firms in Asia.

At the end of 1999 Christian Rönning began UP anew with a substantially reduced, yet highly experienced staff at his side. Torsten Siegel, Georg Maier and former World Champion Stephan Stiegler were responsible for product development, and it was upon their know-how that the first UP Europe product line was based. A new era for UP was firmly established when in just one year UP progressed from the old designs to a whole new glider range including the Pulse, the Makalu, the Summit, the Gambit, the Sherpa, and the Gambit C. UP’s R&D department has since adopted a roughly three-year cycle for the renewal of gliders, which led to a number of even more succesful designs being launched, not least the World Champion 2003 winner called the Targa, the Serial Class reference wing for almost 4 years called the Trango, and later the successor to these, the Targa 2 which won the World Cup in 2004. Torsten Siegel eventually decided to pursue his career goals with Swing, and some time later Stephan Stieglair departed to form his own new brand called Air Design.

Since 2010 the new design team, which picks up the baton from the Stieglair/Siegel years, is headed by Czech industry old-timer Frantisek “Franta” Pavlousek and supported by both new faces and experienced people. In the former category not least German aerospace engineer Matthias Hartmann, who is a passionate hobby paraglider pilot, and Czech young test pilots Michal “Snajby” Sneiberg and Jirik “Jirka” Dlask, and in the latter category German lightweight guru Stefan “Boxi” Bocks.

University of Louvain la Neuve Two Seat hang glider

The club of the University of Louvain la Neuve (Belgium), wanted to make a two-seater hang-glider in 1979. They became interested in the Flexiform Skyline which had a non-profiled sail, which greatly facilitated the sewing work.

Based on photos, they extrapolated their two-seater to scale to be 23sq.m, with a wingspan of 13m. It was desided to truncate the tips of wings at 11m.

To avoid the pilot weight + passenger weight risk of distorting the leading edges, they put triple deflectors.
With triple deflectors and no need to use big tubes, 44×1,25mm resulted in 28kgs weight.

A keel pocket in two parts was sewn in, including 30cms in front of the mast.

For maneuverability it has a trapezoid with a control bar of 1.80 m.

To build a wing that will allow to do all the centering tests without redoing them cables the idea was to use a trapezoidal top in the form of a rail to change the centering between two tests over a length of 30cms, and attach the cables with cable ties, which will only be crimped ‘Once the flight tests are completed!

It flew several hundred hours with several pilots without problems or accidents. It was even ranked 1st in a two-seater competition at the Icare Cup.

Umbaugh Aircraft

1957: (Raymond E) Umbaugh Aircraft Corp
Ocala FL.
USA

Designed by Raymond Umbaugh in 1959 after he had built and sold several examples of single-seat cabin developments of the Bensen Gyro-Copter, Umbaugh Aircraft developed the Umbaugh Model 18 two-seat, jump-start autogyro which first flew in 1959. Limited production followed, including five aircraft assembled and tested by the Fairchild Corporation in 1960.

Had moved to Hagerstown MD, USA, but in 1962 ended operations.

In 1964 Air & Space Underwriters Inc, Munice, Ind, took over assets of the defunct Umbaugh Aircraft Corp in Florida, and moved production tooling to Munice where assembly of Umbaugh 18 gyroplane was to be completed. Air & Space drposited $350,000 with the Tamps Federal Court to pay outstanding claims, with another $100,000 set for another date.

In 1965 production of the U-18 was taken over by Air & Space Manufacturing and the aircraft was redesignated Air & Space U- 18A.
