St. Paul, Minn. — Again with the motor news…? These little contraptions are making quite a… how nicely can I put it? — “joyful noise.” The vote is now history. As I write this in late September, the count has not been made but trends pointed toward acceptance. • Time to take a breather and then move on. Let’s realize that we only have a few hundred of these motor guys. Some flying sites will have to work out compatibility issues, but for the most part powered harnesses, powered paragliders, and nanotrikes allow flight from places closer to home. When they do fly in the company of unpowered hang gliders or paragliders, they are among the quietest of ultralights as their engines have commonly been developed in noise-sensitive Europe. • This column will continue to track the field. But these tiny rigs are simply engines on hang gliders or paragliders and the wings still fly the same (they may even have similar wing loading through the use of larger wings).

ST. PAUL, MINN. — Tucks and tumbles and tails and winglets. What’s happening out there? Rigid wings had good showings at recent competitions and their participation in places with stronger conditions has revealed the value of a fixed tail. Aeros has also fitted sleek winglets to their Stalker 2. My guess is more controlling surfaces are headed our way.  At last summer’s Worlds approximately a third of the rigid wing pilots flew with tail-equipped wings. Some pilots have even made the normally fixed tails moveable. Alex Ploner reportedly installed an electric servo motor on his tail which allows him to set the angle of the tail for climb and glide. At minimum, tails cause a damping of control bar movements which helps in distance flying by reducing fatigue. It isn’t clear if the tail alters the likelihood of the glider tucking or tumbling but contest pilots have said they’ve been helped with a higher confidence level.

ST. PAUL, MINN. — Of course, nearly all the news in the last month has focused on the War on Terrorism. Each of us sees this through our own eyes. We cope with the events in millions of individual ways. A logical way for many hang glider or paraglider pilots is to fly. Many of us find a quiet peace in the air. But in a time of national emergency, officals must make decisions. Among those was the grounding of the entire American aviation fleet, an action that has never occurred in the history of aviation. Naturally, hang gliders and paragliders were included in the grounding. • Led by our capable CEO, Jayne Depanphilis, your USHGA office kept in regular contact with other hang gliding leaders, plus those from the U.S. Ultralight Association, to get word from the FAA regarding the ban on flight and its subsequent lifting. On September 20th, only nine days after the attacks, Jayne said, "I now have it in writing from [FAA official] Mike Henry… that USHGA can operate/resume all aspects of Part 103 outside of Class B enhanced airspace." For those unfamiliar with sectional charts, Class B is controlled airspace around major airline hubs; the "enhanced" part of the new ruling means to-the-ground, rather than the upside-down wedding cake look of normal Class B airspace.

ST. PAUL, MINN., — You know, it seems like quite some time since I wrote about a new flexwing hang glider but in this month’s "Product Lines," I’m pleased to tell you about a new topless entry. It’s AirBorne’s new Climax 154. First some specs: area is 154 squares, span is 34.1 foot, AR is 7.6, nose angle is 127-133 degrees, and it has 90% double surface with 32 battens, a weight of 77 pounds, and recommended pilot weight of 155-275. AirBorne says it takes only 10 minutes to assemble and packs down to 17.4 feet (short pack to 12.8 feet). Well, the specs don’t differ much from any other topless, so let’s look a little further. • The company has already found success with their entry-level Fun, intermediate Sting II, and recreational Shark. As principal Ricky Duncan said, "The only product missing from our range was a truly high performance glider." Besides the obvious removal of upper rigging, they reversed prior AirBorne patterns and went with the more widely accepted elliptical tip and changed their older Shark cam-VG system to allow a tighter VG full-on setting.

St. Paul, Minn. — The buzz continues over power and USHGA. Actually, most of the racket appears to be emanating from a vocal few while most pilots are either ambivalent or fence sitters. • Invited to vote, hopefully all pilots studied the USHGA position and then expressed their interests. Ten years ago, in 1993, USHGA accepted all APA (American Paragliding Association) members into our club. The assimilation worked with few problems. Now the same decision is facing us with power for soaring. You got your voting card. Did you send it? We’re all waiting for you… ••• Executive Director Jayne Depanfilis writes that one reason to think carefully about HG&PG power in USHGA is because FAA is all-but advising the association to take these aviators under our wing. • With that in mind, Jayne asked if I’d go listen to the new FAA administrator speak at the Oshkosh airshow in late July.

ST. PAUL , MINN. — Wills Wing was surely pleased by the recent performances of Nene Rotor who won the Brazilian Nationals in his Talon, and by Chris Zimmerman, who won the US Open on a Talon. Jim Lee came in third on another Talon. lll About their topless entry, Wills Wing says, “After a lot of development and wide ranging experiments… production 2002 Talon 140s and 150s sport a significantly improved sail design, and several new features which are immediately apparent, including an extended tip chord and an extended double surface which fairs in the hang loop, enhanced handling and slow speed capabilities, and improved L/D across the speed range.” s In June I wrote about one of Wills Wing’s experiments seen at the 2002 Wallaby Open — variable reflex. This clever system showed promise but Wills said it “would require a significantly more refined execution in order to be viable on a production glider.” The U.S.

St. Paul, Minn. — At this fall’s meeting of the USHGA board of directors debate will continue regarding the inclusion of powered paraglidersand powered hang gliders in our national club. This debate won’t go easily or swiftly. Many pilots of either wing type feel engines don’t belong in USHGA or at their flying site. Yet the popularity of these flying machines is growing and they are more like us than powered ultralights. • Last month’s story about the Minnesota pilots exceeding 10,000 feet of vertical gain might not have happened without the Mosquito powered harness allowing those pilots find thermals. Besides, the old questions exist: Doesn’t the tow vehicle have an engine? Don’t we have to drive up to most mountain launches? Ironically, the Mosquito engines may use less fuel to get pilots up than a monster 4×4 often used at mountain sites. • So, perhaps you won’t be surprised to read that editor Dan Nelson has asked me to include more power coverage in this column.

ST. PAUL, MINN. — Results are in from the World Record Encampment. In short it was not the year most hoped for due to the massive rainfall Texas sustained. The bad weather was north of Zapata, but it significantly affected those hang glider and paraglider pilots who had converged on the south Texas town. Many pilots had traveled a long way, some internationally. Many got skunked. lll However, some records were set and FAI has already approved a few. s In a “joint flight,” both Pete Lehmann and Mike Barber were awarded the Straight Distance to a Declared Goal record of 516 km (322.5 miles). Lehmann flew a Wills Talon 150 and Barber flew a Moyes Litespeed 4. s Paraglider pilots were perhaps the most celebrated of the 2002 Zapatans since two pilots managed record on successive days (before the rains started). Dave Prentice flew his Ozone Proton GT Small for 386 kilometers (241 miles) earning a Straight Distance record.

ST. PAUL, MINN., — When they first named it the World Record Encampment (WRE) last year, the name seemed a little pretentious. Then, lo and behold, with help from weather technocaster, Gary Osaba, records were set. The 300-mile barrier that had alone been the domain of Larry Tudor — who’d, impressively, done it twice — fell not once but twice. • Dave Sharp held the record for mere days before Davis Straub smashed through to log his now-recognized World Distance Record of 347 miles. Both flew rigid wings and Straub was able to retain the title for a whole year. (Are we talking "Internet time," or what? Used to be records stood for years, even decades. No more…!) ••• As this year’s WRE started anticipation was high. Last year, others whispered about and Straub waxed enthusiastic about breaking the 400-mile barrier. Davis was sure it’d be done. The 2001 edition of the WRE started "normally" in the heat-baked terminology of Zapata, Texas — an obscure location now thrust onto the world’s radar owing to the flight accomplishments in 2000.

St. Paul, Minn. — High times in Minnesota… a story about great thermals up here in the southern Tundra. In late May this year, a group of Minnesota pilots had flights that may have set a record for the midwest. Bruce Bolles, who formerly worked with me at BRS parachutes, related events of this surprising day. • Bruce’s Flytec logged a gain of 10,460 feet from the landing area. He could’ve gone a bit higher (one pilot did) but at that height the temperature was 21° with a 30 mph wind chill equating to something like zero. Bruce had gloves on but none of the pilots expected such huge altitude gains so they weren’t dressed for the occasion. Minnesotans are keenly aware of factors like wind chill, so Bruce wisely elected to go down to warmer altitudes before he sustained frost bite damage. “I couldn’t feel my nose or thumbs,” he recalls.
