Cockpits Get Smarty

The Evolution of the Glass Panel

General aviation has been begging for something truly revolutionary for decades. Though a series of sidling advances have seen manufacturing revolve—in circles that is—from its robust wartime days, little evolution has occurred in the way we fly. The airframes we construct today remain markedly unchanged. Rigid sheet metal flivvers, tubular frames, and crafts of wood, fabric and composite construction are still pervasive.

A look from the inside out perhaps tells a different story. Significant evolutions have arrived in the cockpit, in the ways we navigate and communicate. Though it’s reasonable to posit we still aviate like it was 1863. That’s when French writer and naval officer Guillaume Joseph Gabriel de La Landelle coined the word aviation, from the Latin avis expressing bird-like qualities. In those very early days, navigation and communication were absent the flying vernacular. Flight was rigid, and aviation was done by the seat of one’s pants.

Classic Cub Panel
The classic Cub panel, a precursor to the six-pack.

While in the age of “steam gauges,” instruments relied on classical physics and coarse (vs. discreet) sensors to quantify relevant aviation data in the airspace environment. Their measures gave latent, relative indications of: wind, ground and vessel movement; time and distance travelled; and propeller revolutions as an expression power and efficiency. The basic instrument panel comprised a set of commonly round dials and, adjunctly if at all, a two-way radio and position transponder. Steam gauges served for decades until the dials’ limitations were foiled by the digital age.

Thankfully modern cockpits strived, at their very least, to bring to bear all three maxims—aviate, navigate and communicate. The fundamental change at hand was arithmetical precision with which power, speed, space and time could be governed. This all happened abruptly at the turn of the century that was Y2K (an alarm expunged in its own hype). The successor was GPS. In this new era, flight specifics were plotted digitally, accurately and nearly instantaneously.

Round dial gauges of the then common analog six-pack transformed to a new silicon standard with GPS at its core. The change started in general aviation with the handheld navigator. Quickly, a preponderance of silicon-based tools, portable devices, found their way into the cockpit. This justly led to their panel mounting, freeing the hands and cockpit of clutter—albeit busying the fingertips.

GPSMAP 496, SL40, GTX 327 stack
Going from “steam gauges” to “glass panel” started with the panel mounting of a handheld GPS.

In step with the May 2000 demilitarization of GPS technology, and freeing impediments on its accuracy, analog gauges began exiting the cockpit. Much like digital television and flat screens did away with the picture tube, so went the round dials of the instrument panel. The “glass panel” cockpit, a perhaps more seductive term than flat screen avionics, became pervasive. Glass panel innovations took their lead from military cockpits and the personal computer. Digital displays emerged and the analog six-pack was cast aside.

Dynon D100 EFIS / D10 EIS, GTX 330, SL40, GPSMAP 396
Glass panel / flat screen avionics brought silicon to the cockpit.

The glass panel would change flying forever. Celebrated at the outset of this transformation was the Dynon EFIS-D100, a first among many EFIS (Electronic Flight Information System) offerings, giving pilots a glimpse of the future. Crystals snuffed out cathodes, dials turned to tapes, and LED arrays replaced needles. Every detail, and then some, of the six-pack panel cozied its way onto illuminated flat screens.

The mid-stream standard glass cockpit, a panel-mounted multifunction handheld device.

As Dynon Avionics continued to innovate, with Pocket Panels and touch screens, a run of popularity endured. Currently, the producer-dynamo has evolved all its strengths into the SkyView HDX, an extensive glass panel device that encompasses just about every cockpit function. Likewise, Garmin arduously moved its portable and mountable GPSMAP x96 series of similar functionality to the present G3X integrated flight deck.

Analogous to Moore’s law—a size to capabilities equation—screen sizes increased and functionality multiplied with each successive release. Cockpit devices thrived on integration, faster speeds, and touch screen advances. The driving elements behind the modern glass panel revolution were enhanced silicon and innovative software.

Garmin G3X
A single touch screen display encompasses all the basics and then some, necessary for flight.

Other vendors followed in form, some leading in their own unique ways. A software approach from Airbox Aerospace Limited, a U.K. based firm, was to “present only the vital information.” In doing so, Airbox created a navigation technology combined with its Aware airspace warning system. Though still in the portable genre, the system took full advantage of the country’s National Air Traffic Services. A combo flight planning, inflight and approach GPS-based unit provided pilots with a moving map over ICAO charts plus alerts of impending airspace infringement. Its alert feature was, in principle, similar to what ADS-B strived to do in the U.S.

By comparison, TruTrak Flight Systems with its EFIS device (now proffering under the BendixKing brand) took perhaps too literal an approach by choosing to focus on “flyability and ease of operation.” Analog dials, thought to be best by the company’s creator, were merely represented in digital form on a new lightweight, flat square screen. One might say it was a six-pack served like a boxed wine, flyable if familiar.

Simultaneously others in the experimental realm, GRT Avionics for instance, subscribed to an “all-in-one” format delivering integration, rich features, and flexible operation with their line of displays. GRT’s EFIS offerings landed agreeably with experimental aircraft builders giving buyers a wide selection of displays, packages and options.

Openness is a trend in information systems development, one which encourages third party collaboration. On a platform of open avionics emerged NextGen Avionics with its antithetical “dumb is the new smart” motto and “highly modular” as its theme. Their flight deck display systems encouraged the integration of remote mounted input/output devices while the glass box was but a facade to present the data.

Meanwhile, Mid-Continent Instruments devised its SAM and FLEX. The latter being a custom function designable display, essentially an open drawing board in a standard two-inch round package. Today FLEX is not alone as uAvionix, Garmin and Aspen have fielded multi-function devices that follow the circular cutout route. SAM, for Standby Attitude Module, was launched with the TruTrak simplicity approach yet aimed purposely at the certified market. It required a rectangular cutout, presenting just the vitals in a familiar analog fashion.

Garmin G3X, GTN 625, G5
An all-on digital affront eliminates analog gauges, adds redundancy and an autopilot.

In addition to the six-pack, radios and transponders went the way of glass and digital. The upgrade path was enunciated by NextGen, referring now to the Next Generation Air Transportation System (not the avionics manufacturer). As with anything FAA, NextGen ushered in another acronym—at last count 6,000 plus—the aforementioned ADS-B. With the “S” standing for surveillance, make no mistake it is more about surveillance than alerting, as was Airbox. Today’s transponders, supporting Extended Squitter on the 1090 MHz frequency and broader bandwidth on 978 MHz, signify digital communications are now all “In” by federal mandate.

Broadened communications introduced by ADS-B also meant greater amounts of data sent to the cockpit. This data arrived as an in-cockpit visual of course, and while timely, informative and indispensable, it introduced obstacles of its own. Primarily, an over-dependency, i.e. fixation, on the glass panel translates to less time spent on the actual see-and-avoid (eyes outside the cockpit) axiom. This is particularly relevant in general aviation whether flying visual, under instrument rules, or at night. Looking for possible incursions, be they weather, terrain, objects, or the sort, still remains a responsibility of the pilot, with or without the supplemental data of a digital cockpit. The sanctimonious sequence of aviate, navigate, communication is beset by clouds even with the glass panel.

The Virtual Pilot

The modern panel essentially strives to replace the windscreen, like it or not. Flying by the seat of one’s pants, perhaps now uncomfortably numb, has been removed from the pilot’s arsenal (arse pun intended). The once popular notions of cockpit situational awareness and relying on instinct, both acquired by experience, have actually started their devolution into a virtual affair.

For the early Grasshoppers, all flying was by feel. Flight instruments of any consequence were neither supplied nor required. A compass and a fuel gauge, a tachometer and an oil pressure indicator were their only luxuries beyond an ingrained love for flying. – Operation Grasshopper by Dario Politella

Flat screen technology is really about integration, whether panel mounted or handheld, via iPad, Gamin aera and their likeness, or dedicated displays such as Garmin G3X and Dynon SkyView. Today’s cockpit is a multi-vendor system with various devices aggregating data and depending on software to drive them. As features grow complexity grows, emphasizing the trouble with the virtual world. Will there ever be enough automation, and is reliability ever a sure thing?

Apple iPad, Garmin GTR200, GTX335
A panel-mounted iPad offers carry-in and carry-out capability with easy device management.

While it remains a critical maxim: aviate, navigate and communicate does not cover the pilot’s entire playbook. There’s now a ton of feedback pertaining to the monitoring and controlling of a flight. As a surveillance technology, the virtual cockpit only serves as a barking watchman. Sophisticated glass panels combine autopilots and scads of system data, presenting all in broad detail. The virtual cockpit offers scenarios never before considered, often blurring priorities. While it’s still up to the pilot to fly the plane, an abundance of data brings with it a profusion of additional decision making possibility, and perhaps diffused awareness.

Garmin aera, G5, JPI 350, Trig
Going digital yet keeping it simple with cockpit glass: Garmin aera / G5, JPI 350 engine monitor, and Trig compact radio / transponder.

Avionics development and acquisition was strong prior to 2020, driven largely by ADS-B regulation. Stepping back though, progress has been quite significant. A few decades ago pilots were navigating with maps on compass headings and only just beginning to make copious use of GPS.

At their fingertips, pilots now find a wealth of data… weather, terrain, charts, obstacles, scenarios, tables and procedures to name a few. All are sitting on top of what seems so ordinary, a moving map. It’s a daft reminder of the old school windscreen.

While the integration that we’ve achieved is impressive, consider the scads of data and their instantaneous inquiry onto the glass panel. Notations and calculations, books and binders, and all the distractions from the essential windscreen have been digitized. Everything is there at the touch of button. This alone is an enormous achievement in aircraft development. But what about the pilot?

Now absorbed in the virtual screen before them, pilots still yearn for more. Adding to the flying space of aviate, navigate and communicate are additional audio sources, namely the cell phone and music. Crowded and overstimulated, pilots are simultaneously presented with possible outcomes in both the real and virtual environment.

As the virtual cockpit is upon us, what next? By definition a birdbrain lacks capacity for, say, the finite amount of data we process on preflight alone. A human brain attacks this with a presumptive checklist, but the bird flies without one. It is precisely a bird’s freedom of movement that we wish to replicate. With them such freedom is innate. However, we lack their unique skeleton, airframe dynamics, and instinctive flying ability. We therefore must endeavor to invent the ultimate machine. Only in doing so can we achieve the same freedom.

From There to Here

We celebrate the today’s digital cockpit and its byte-sized impact. The glass cockpit was originally pioneered during the 1970s and 80s in NASA’s 737 flying laboratory at Langley Research Center. Heavies began incorporating them in the ‘90s as airframes outlasted powerplants, systems and avionics. Everything from freighters to cabin class aircraft were ripe for upgrade. Avionics replacement has led the retrofit march ever since.

Restoration, modernization and refurbishment gave aging aircraft new purpose and glass panel upgrades were at the forefront. They were more than merely a fresh coat of paint serving a more youthful appearance, or new wheels and a plush interior impressing that like-new, cozier feel. The satisfaction of an updated instrument panel is in fact more cerebral. A glass panel appropriation redefines our ability to fly and to be free from analog limitations, mechanical constraints, and environments prescribed in convention.

Benefits of the glass panel seem obvious, though selecting a system perhaps more subjective. With glass one achieves redundancy and enhanced backup capability. Solid state electrics imply reliability, speed and precision. Less weight and lower power demands mean fuel savings, conceivably extra payload too. Maintenance costs may be reduced, though software subscriptions enter the fray. Flying is theoretically easier and focus on the aviate function is abundantly enhanced. Adopting the glass cockpit, costs aside, operators have reverently brandished the phenomenon.

The glass cockpit eliminates the six-pack, replacing it with more.

Even the purist wishing to keeping an aircraft authentic has succumbed to some degree of glass, if only for purely practical or singularly subjective reasons. As a showcase of sophistication, and a paradox as to why, the Cub offers an example. Flying with the basics: a tachometer, airspeed indicator, compass, altimeter and engine oil/pressure meter, in a clear skies is wholly sufficient for this type of aircraft. Moreover, it’s properly flown by the seat of one’s pants.

However, every justification seems warranted when modernizing the Cub’s panel and flying one with glass merely crosses the line of paradox. Now common in our vernacular, the glass panel makes flying a Cub simply more extraordinary. Truth is, the Cub had already attained such praise well before the glass panel arrived.

Keeping it real for the aviator purist. The original Cub panel offered power, speed, direction and altitude without all the fuss.

Relevant information supplemented by a wealth of it, all at the press of a finger, that’s the plus of a well-appointed instrument panel. These days there’s no shortage of ingenuity to bring the glass panel to life. But the horizon is forever, as is a pilot’s longing for more. Let’s see where airframe design takes us in the next century. Virtually anything is possible. Let’s keep it real, and safe, for flying’s sake because after all, aviation takes place outside the windscreen.

Bearhawk Aircraft to Increase Production to Meet Demand

AirVenture Momentum Pushes Bearhawk Kit Backlog Beyond 2022

AUSTIN, TEXAS, SEPTEMBER 20, 2021 – Bearhawk Aircraft announced today the company is ramping up production at its manufacturing facility to meet increased demand for Bearhawk quick-build kits. The company offers a high quality kit of parts and assemblies used for the construction of Bearhawk two, four, and six-place amateur built aircraft. At present, five models are available in both plan and kit form, including the original Bearhawk 4-Place, two-seat Patrol, Companion and LSA, and the newest Model 5 with seating for up to six. Kit production takes place at a company owned facility in Atlixco, Mexico.

Bearhawk Aircraft participated in this year’s EAA AirVenture fly-in in Oshkosh, Wisconsin. Exhibiting in the experimental aircraft area were Mark Goldberg, manufacturer of Bearhawk kits, and numerous members of the Bearhawk community, plus aircraft on display including the Model 5, its largest that can accommodate engines up to 315 horsepower.

According to Goldberg, “Oshkosh 2021 was very busy for us. The crowd was undoubtedly attracted to the Model 5 sitting on 31-inch Alaskan Bushwheels at the front of our booth. We had ton of interest in all our models, and the most sales ever at the show this year.”

Presentation Highlights

Two informative events held during and post-show AirVenture Oshkosh 2021 were presentations given by Goldberg relating the backstory of Bearhawk Aircraft and describing the various models that have evolved from his collaborations with Bob Barrows, designer/engineer of the rugged line of Bearhawk aircraft. The first was a “Homebuilts in Review” session, held mid-week during AirVenture and hosted by Joe Waltz of EAA’s elite Homebuilt Aircraft Council. The presentation featured the Bearhawk Model 5 in situ and an interview with Goldberg. Waltz gave an informative interview drawing upon his experience as advisor, builder, and careers as both Air Force and airline pilot. The ‘Bearhawk Aircraft Presentation at Oshkosh 2021’ can be seen here: https://youtu.be/hmOAEQkyZlw.

The second presentation was EAA’s weekly webinar series held on September 8, 2021. In the program, Mark Goldberg discussed the current five aircraft offerings, responding to listener and moderator questions. The two Bearhawk presentations offer a glance at what makes the aircraft so appealing to pilots and builders. Sturdily built, Bearhawk aircraft deliver a broad performance envelope that optimizes both speed and short-field operations. In addition, their unique load carrying abilities make them suitable for both cross-country and backcountry travel. The archived webinar can be seen here: https://www.eaa.org/videos/6271502678001.

Goldberg has been involved with Bearhawk for more than 20 years. He built his first Bearhawk, a 4-Place model, at the launch of the kit manufacturing business. Previously he was flying a RV-8 he had built, but felt the need for an aircraft he could fly more safely into unpaved strips. Goldberg attributes first becoming aware of the Bearhawk design to a Sport Aviation magazine article from 1995, at which time the only aircraft examples flying had been built from plans—a time-intensive process. Today, Bearhawk quick-build kits can be completed in around 1,000 hours, as evidenced by the 120+ currently flying.

Backstory Highlights

Visitors at AirVenture often ask, “Why is the Bearhawk better?” The cool and casual response from Goldberg, and Barrows, often starts with a modest description of the Bearhawk’s technical prowess. For starters, Bearhawk wings form a constant airfoil with aluminum skin and flush rivets; a smooth surface translates to aerodynamic efficiency. This contrasts with fabric covered surfaces that form scallops between structural members.

Barrows worked with Harry Riblett on the design of the self-named, 10-percent thicker (roughly one-inch taller) airfoil now used on all Bearhawk aircraft. The product of their efforts was an optimized wing with 1–2 knot slower stall speeds and up to 5 mph gain in cruise speed. Also remarkable is that each Bearhawk model is designed to Utility category strength at full gross weight. Barrows places this, along with weight savings, at the top of his design criteria. More highlights are revealed in a 17+ minute YouTube interview, ‘Bearhawk – Bob Barrows’ Approach to Airplane Design.

Bearhawk Model 5

The Bearhawk Model 5, fifth in the series, retains the classic styling of previous Bearhawks. It is a familiar high-wing design, a product of the ages and time-tested. As a conventional gear aircraft, it performs safely and predictably, especially on unimproved strips. The most notable change from the 4-Place is that the Model 5 is bigger, seating up to six. The two Bearhawks might be compared to the Cessna 180, a 4-place aircraft, and the larger Cessna 185. However, the Bearhawk is lighter and stronger, and can haul more with easy access through its large cargo door. The YouTube video, ‘A Walk Around the New Bearhawk Five with Builder Collin Campbell,’ provides more detail.

As previously noted, Goldberg started his first Bearhawk with the idea that he would manufacture quick-build kits so others could save time in completing their aircraft. He understood a few key points before launching his project. First, good tooling makes parts repetitive and interchangeable. With regards to welding, a stable fixture ensures an accurately manufactured frame—the component on which all other parts rely. Each Bearhawk frame is MIG-weld tacked, then inspected for gaps per specification. Final welds are done using oxygen acetylene (gas), a method preferred by Bob as historical, still flying airframes were done this way. Thinner material, such as on tail surfaces, is TIG welded. More on this and other manufacturing techniques can be learned in a YouTube video titled, ‘Bearhawk Factory – How We Make the Kits.

Other things learned in the presentations and videos about the Bearhawk that contribute to its popularity include airfoil shaped tail surfaces adding 20-percent performance increases with their greater surface area on horizontal and vertical stabilizers. The larger 4-Place and Model 5 Bearhawks approach at between 55–70 mph with their large 9’-2” long flaps. Touchdown is 40 mph in ground effect, equating to 43–44 mph stall in air. The 2,000-lb gross Patrol is so stable that reaching aft CG (center of gravity) condition is nearly impossible. Empty, it weights 1,100–1,230 lb. The Patrol touches down at 35 mph, cruises at 150–155 mph with a constant speed propeller, and at 140–145 mph with fixed pitch. Compared to a 90-mph Super Cub, however, the Patrol will get in and out of all the same places. Finally, check out how loading and hauling is accomplished with a Bearhawk. The YouTube video ‘Bearhawk – the pickup truck’ is a 30-seconds time-lapse showing the transfer of a loaded 4-Place Bearhawk to the bed of a pickup truck.

All Bearhawk models appeal to backcountry and cross-country flyers alike, and can perform a variety of flying activities. The 4-Place Bearhawk fills a utility and transport role extremely well with its large cabin. The Bearhawk Patrol is a tandem two-place version that excels at accessing remote airstrips. The Bearhawk Companion is a side-by-side 2-place model with superior strength and payload capability. The Bearhawk LSA is a lightweight design that meets U.S. Sport Pilot requirements. The new Model 5 seats six and is powered by up to 315-hp engines. Each aircraft excels at stable slow flight and attains higher than expected cruise speeds. Bearhawk Aircraft manufactures high quality quick-build kits for all models.

Bearhawk Trifecta – New Zealand Sport Flying Magazine

For the third year in a row, Bearhawk pilot Jonathan Battson won the annual Healthy Bastards Bush Pilot Champs STOL (Short Take Off and Landing) competition. The event is held in Blenheim, New Zealand, home to the Omaka Aviation Heritage Centre — a “living” museum commemorating the two World Wars. The main objective in the STOL component of the competition is to get airborne in the shortest distance, and then touch down safely bringing the aircraft to a stop also in the shortest distance. Battson took top spot in the Heavy Touring Category (>2,550 lb) in his Bearhawk 4-Place aircraft. As has become customary for Battson in the Bearhawk, his winning score was by a wide margin. Battson completed the trifecta of wins in 2019, 2020 and 2021.

Whether flying for sport and recreation, to make the best use of one’s time, or out of basic necessity, there is no equal to the Bearhawk. A triphibious Bearhawk with its array of landing options, carrying capacity and superior strength is prepared, all around, to ensure each challenge is met with reliability and strength. The combination of wheel, ski and float options on the Bearhawk, along with three successive competition victories, exemplify trifectas of achievement—that involving three successful outcomes.

Bearhawk aircraft are available in kit or plan form. Models range from 2-, 4- and 6-Place configurations. All Bearhawk aircraft excel at accessing remote airstrips and are renown for their rugged construction and carrying capacity. Avipro/ Bearhawk Aircraft manufactures high quality Quick Build kits for the Bearhawk 4-Place Model B, Bearhawk Patrol, Bearhawk Companion, and Bearhawk LSA, and Bearhawk Model 5.

American Legend Aircraft Company Delivers MOAC, LSA, Kits, Restorations and Wins STOL Competition with its Legend Cub

SULPHUR SPRINGS, TEXAS, JUNE 23, 2021 – American Legend Aircraft Company announced today successive deliveries of MOAC, LSA, and Legend Cub Kit aircraft, and a restored Super Cub. A recent visit to a National STOL Series event saw Legend Cubs take the top four positions in a single category.

The Texas-based manufacturer has been in operation since 2005, earning its reputation as the preeminent builder of the classic high-wing, tandem seater. The array of offerings at Legend today highlights the best practices of Cub construction. According to Darin Hart, company president, “Sales have boomed since September 2020.” Here’s a sampling of what has been produced.

MOAC / Super Legend XP

MOAC, the Mother Of All Cubs and a Legend original, is an experimental certified Legend Cub with a gross weight of 2,000 lb plus the ability to accommodate three persons. Recent MOAC builder/customers include Brian Steck of Mineola, Texas. Steck flies often for business in a pressurized Piper turbine, but for fun he chose MOAC. Its seats tell the story with “Scooter” embroidered on the front position and “Along for the Ride” at the aft place. Steck spent hours at American Legend Aircraft Company hands-on in the construction of his customized MOAC. It first flew in March 2020.

Also in the recent release lineup of Super Legend customers was repeat owner Greg Rodriguez of Franklin, Louisiana. Rodriquez’ new AL18, with its carbureted Continental OX-370 engine, was coincidentally inspector Mel Asberry’s 1,000th aircraft certification occurring in December 2020. Rodriguez previously flew an AL3 on floats. His flying companion in Louisiana took delivery of a new Legend FloatCub, on PK straight floats, in April 2021.

Legend Cub S-LSA

The S-LSA Legend Cub is ASTM certified at 1,320-lb gross weight. It’s the paradigm of the popular Legend fleet and has been in production since 2005. The aforementioned Legend FloatCub is also an ASTM certified S-LSA with a 1,430-lb gross weight allowance.

With pre-owned Legend Cubs in high demand these days, the factory has three of its AL3 versions scheduled for delivery this year, one of which is headed to Australia shortly. In addition, the first-built Tweety is back, having been completely restored with a few updates.

Legend Cub Kit

While MOAC is a builder-assist aircraft produced at the factory to satisfy higher gross weight certification, kit versions of the AL3, AL11 and AL18 models, on the other hand, are shipped for assembly outside the factory.

Jim Clements of Cresson, Texas is building an AL11, while Sheldon Stewart of Godley, Texas is completing an AL18 kit. Tooth puller Dr. Bob Erickson of Bangor, Maine is 12-plus months into his project, “The Extractor.” It will feature dual Dynon SkyViews. Meanwhile, a student-built Legend Cub STEM project is well underway in McKinney, Texas.

Kit-built Legend Cubs are completed by their builders then certified under the FAA 51-percent rule for amateur-built aircraft. Construction is straightforward and well-documented. A Legend Cub kit eliminates the need for specialized tools and fixtures. Each airframe is fully welded and sealed from corrosion, and the all-aluminum wings are fully riveted at the factory. Assembly is all that’s required of the nuts, bolts, cables, pulleys, fuel lines, fittings, etc.

Restorations

Every Cub has a story. What makes this one remarkable are its two new owner/caretakers who operate other aircraft for a multitude of reasons, yet fly this one solely for the fun of it. Celebrating this Super Cub restoration only begins with its paint scheme. Extra equipment on board reveals a covetous pick list of STCs and so-called Alaska mods: Power-saving and brighter LED lighting; Shock absorbing polymer suspension by AOSS with safety cables and giant tundra tires; Dual cargo doors for stowage both behind the rear seat and in the turtle deck; An advanced panel just in case your eyes wander inside the windscreen.

– Legend Cub –

Additional Super Legend XP / MOAC aircraft you may have seen:

Oregon based Super Legend XP built by Chad Russell. This full extreme experimental Legend is a real backcountry aircraft yet it’s equipped with an IFR suite of Garmin avionics including autopilot.
Russell chose a Legend Cub for its build quality, fit and finish, and durability. He also wanted a new IOX-340 stroker engine. A detail-oriented person, he noted, “The total harmony I feel flying a well balanced Cub, even at 85 mph, is about the best thing in life!”
Tony Kasabasich of northern California created the Shock Monster system for enhanced backcountry flying. He flies Shock Monster exclusively on his Super Legend XP.
Russell and Kasabasich are members of the Flying Cowboys and STOL Rats, champions and promoters of backcountry aviation.
The Super Legend XP takes full advantage of the extended landing gear, fat tires, and of course the Shock Monster system by TK1 Racing.
Bo Ellis completed his MOAC in Fall 2019, including a Cessna-style square tail.
Ellis is one of the High Sierra Fly-In organizers, a STOL drag racing event held annually on Dead Cow Lakebed in the Nevada desert.
