KITPLANES Review: Sportsman in Transition

1

Experimental aviation, full of trendsetters and outliers though it definitely is, often follows a predictable path. Companies come and companies go. Aircraft designs are born, succeed, evolve, die. Tastes change in our world, though, and it should be noted, the overall gravity of Van’s Aircraft’s success creates both an expectation of supply and support, but also can influence development plans. No doubt Experimental aviation today is a mature field, less full of wild-eyed inventors and more occupied by kit- and plans-supplying companies refining their products and business plans in equal measure. Homebuilders expect.

Which brings us here. This Glasair Aviation Sportsman might just be a unicorn. It exemplifies a recent burst of development on the design—whose roots date back to the GlaStar of 1994—but is an airplane that, as a practical matter, you can’t actually buy. As this is written, Glasair Aviation has hit the “pause” button, laying off its production staff, taking no new orders and halting work at its Two Weeks to Taxi builder-assist facility—the last item just one side effect of COVID-19 social-distancing restrictions. It’s retaining a small support and engineering staff with an eye toward relaunching in 2021 with a substantially revised product.

Since the launch of Two Weeks to Taxi in 2006, the company has focused on that program and continued to develop the kit to be a better fit there, which meant de-prioritizing the Sportsman as a more traditional build-it-at-home kit. In recent years, TWTT-completed airplanes outnumber those built in garages and basements by a wide margin. That may or may not continue to be the case as the company reintroduces the model with what it says will be significant improvements. Some of those they hinted at with me, some they wouldn’t talk about, but I was given enough of a briefing to understand where the company is trying to take the design and can guess, because of my experience with the Sportsman, how it might go about reaching those goals.

Why Are We Here?

It’s a fair question to wonder why we’re featuring an airplane you can’t buy today. The answers are actually pretty simple. The basic design is not going to change in fundamental ways—the wing stays on top, the tail stays at the back and steel tubes remain inside a composite fuselage shell to support aluminum wings. When it returns, the Sportsman will still be convertible to both tri-gear and taildragger configurations, as well as going onto floats. There’s actually another reason to check in with the circa-2020 Sportsman: The company has upgraded several aspects of the Sportsman since we last flew it—and radically so since I last flew mine in 2011—all of which will carry over into the new version.

From the outside, not a lot has appeared to change, but what does stand out is the superlative paint job on the factory demo, which is said to be representative of the paint-shop capabilities that Randy Lervold, recently hired as Glasair Aviation’s CEO, has worked hard to implement. Indeed, paint had been a sticking point, so to speak, on the TWTT aircraft. Early versions left it to the builder to source painting, though the program evolved into referring builders to local resources and then managing that part of the program for the builder in the most recent examples. Lervold told me that painting and overall detail wrap-up were among the most time-consuming steps in the build. Getting the Sportsman from a rack full of parts to something ready to start up and taxi in a couple of weeks is easy compared to finding a good painter, or so it seems.

New leather seating surfaces, a refined instrument panel and significantly darker hue to the interior gives the factory Sportsman a more sophisticated appearance.

Changes to the Sportsman’s interior are startling. Where they were typically all gray inside, sometimes described as an “Arlington bass boat,” the 2020 Sportsman is all cool, broody tones. The steel-tube fuselage cage is a deep gray, the seats are nearly black, the glareshield is larger and dark and the combination of carbon-fiber panels and accents gives the Sportsman the feel of a production airplane. (Yes, that’s a compliment.) The seat cushions are reshaped, sumptuous and AmSafe airbag seatbelts are a $2895 option.

You old-time builders are rolling your eyes, thinking that interiors ought to be light, functional and cheap. Traditional aesthetics amount to rounding off the sharp edges, dabbing paint on a few screw heads and moving on. But don’t forget that the price level where the Sportsman lives includes spousal buy-in. Non-pilot family members take interior quality and comfort seriously.

Current Thinking

Today’s Sportsman panel is an evolution of the first fiberglass “molded” panels that started back in the two-seat GlaStar days. But, now, it’s made of carbon fiber and lacks the segmentations that used to denote conventional radio racks. Today’s airplane has one large panel populated, in this case, with a 10-inch Garmin G3X Touch on the left, a GPS 175 IFR GPS, GTR 200 com radio, G5 backup EFIS and GMC 507 autopilot controller in the center. A remote-mount transponder rounds out this airplane’s avionics. It’s worth noting that the right side of the panel (covered by ay iPad in these photos) has a cutout for a second G3X Touch screen and is already wired; it’s fairly trivial to upgrade to a second screen if you want. As someone living through rolling avionics upgrades, I can tell you this is not an insignificant detail.

This Garmin-based system includes a single G3X Touch EFIS with engine monitoring backed up by a G5 instrument. The iPad covers the blank for a second screen.

“Boat-style” rocker switches below the main EFIS handle the systems, with a small subpanel to the left with the ignition key, P-Mag electronic ignition switches and toggles for fuel transfer from the outboard auxiliary tanks to the inboard mains. This layout is cleanly laid out and easy to use. For the most part, it conforms to concepts familiar to those coming from certified aircraft, so that it’s likely the biggest challenge will be recalibrating from a yoke or a side stick to a center control stick. (Which, if you have a pulse, takes about 10 minutes.)

So Let’s Go

In all the important ways, the modern Sportsman is a conventional light aircraft. Start the big Lycoming through the usual procedures for an injected engine, get the avionics going and head for the runway. I’m not sure exactly why, but the new Sportsman feels really solid, the free-castering nosewheel tracking the taxiway without a lot of attention—on an admittedly near-calm day—and the big rudder doing most of the work pointing the airplane’s nose. Runup is about like you’d have in, say, a Skylane except for all the glass and the need to check that each P-Mag runs on its internal power. Set the trim with the hat switch on the stick, pop in a notch of flaps via the lever between the seats and you’re ready to go. (Lervold asked me if I thought the airplane should get electric flaps. Being old-school myself, I glared over my readers with a “don’t touch that” look and he just nodded.)

A Two Weeks to Taxi aircraft as it looks near the end of the first week (left) has the engine mounted, wings ready to go and most systems in place. Like a lot of homebuilts, there are numerous stages of assemble and disassemble until it looks like this (right).

Thanks to having most of the options on board for a tricycle-gear version (including a detailed paint job), this Sportsman weighs 1525 pounds empty. Maximum gross is 2500 with the carbon-fiber fuselage option (2350 without); with the main tanks full (30 gallons) and Randy and me on board, we were about 435 pounds under max gross. Filling the aux tanks (for a total of 50 gallons), would leave about 315 pounds for baggage and passengers.

The IO-390-powered Sportsman has always been good on the runway, accelerating quickly to the 50-ish-knot rotation speed, climbing strongly at max power and going uphill at better than 1000 feet per minute in cruise climb of around 90-95 knots indicated. (Best-rate airspeed is 85 KIAS, which provides 1200 fpm at gross.) Overall, the Sportsman likes a little less deck angle for visibility and engine cooling, but it has the performance to give up. Cruise performance on the IO-390 is 143-145 knots true at 8000 feet density altitude on 11.5 gph rich of peak EGT—go lean of peak and just under 9 gph, and you’ll see right around 140 KTAS.

Handling Up There, Down Here

Don’t you hate it when pilots describe an airplane as “honest”? It sounds like a cop-out, a crutch when you can’t say anything more detailed about the thing. Problem is, that term perfectly describes the Sportsman. It has very good longitudinal stability—meaning it stays on trimmed airspeed without much attention—it has good yaw stability, which is good for turbulence. It’s maybe not quite as yaw stable as a Skylane in the bumps, but it is good and doesn’t do that corkscrew deal in turbulence like your friend’s Bonanza. The Sportsman, like the GlaStar before it, has rightly been criticized for heavy roll effort, and even though the latter Sportsman aircraft have had servo tabs fitted to one aileron (the other wears roll trim), the design comes nowhere close to that two-finger responsiveness you get in a Van’s. Then again, it’s also a utility/travel airplane, and you’ll only really scrunch your nose if you’ve been flying RV-8s for the last few years; most pilots coming from certified iron will deem the Sportsman to be light and responsive.

A single servo tab, seen on the inboard section of the aileron helps reduce roll forces in cruise.

Lervold and I meandered over from the Arlington, Washington, base to the Orcas Island Airport for a few touch and goes, and it all came back to me. Speeds are higher than for my lighter GlaStar but still moderate. Plan on 60-65 KIAS down final with full flaps and a short rollout. The heavier Sportsman, with a 74-inch constant-speed prop, sheds energy quickly at idle power, which is a nice thing. It also accelerates briskly, even with full flaps. All the sightlines are good in the trike—and even very good as a taildragger—though it took me a few minutes to become accustomed to the seating position and taller/deeper glareshield. Together with the new dark color for the steel-tube cage, the new Sportsman felt less “open” than my own low-panel GlaStar and even than my old Sportsman. But memory is terribly fallible.

The Debrief

Lervold and I spent a bit of time after the flight talking about the next steps for the company, though he was careful not to let on too much. First off, the company can’t continue to offer its Two Weeks to Taxi program as long as social distancing is still a thing. He also feels that over the last few years not enough effort was put into some engineering aspects of the design, and he wants to take time during the pause to work on detail improvements.

LED landing lights finally became an option this year .

But there’s more, and here I’ll offer my take on what the Sportsman needs to be more desirable. First off, I think there’s some cruise speed to be found. Overall it’s a clean airplane with a reasonable, 133 square-feet of wing. We’re not in Cub category here, so all else being equal, there should be some more velocity in the design. It’s not a completely fair comparison, but the Van’s RV-14A, with the same engine and only slightly less wing area (126 square feet), is at least 25 knots faster. It is, however, some 500 pounds lighter and has only two seats. My point is that the Sportsman needs to trim that gap.

Speed losses mount quickly from both induced drag and drag from cooling. The IO-390 uses oil squirted to the undersides of the pistons for cooling and that taxes the oil cooler. One solution has been to open up the system and fit larger coolers. But I think the airplane would benefit from a disciplined engineering effort to improve cooling and reduce drag. This is not quick work but it pays off in the end. Think of what Roy LoPresti did for the Mooney airframe back in the 1970s; the dowdy M20F became the sleek and substantially faster 201. Oh, and there is the IO-390-C variant that offers a rated 215 hp.

The rear-facing passenger seats have been on board for some time. They provide rear-seaters with more leg- and headroom as well as a better view of the outdoors.

I would also raise my hand for more fuel capacity. Currently, the Sportsman has 50 gallons spread across four tanks, an artifact of the GlaStar design; these are aluminum tanks carried inside the wing structure. I was the first to use the IO-390 in the Sportsman, and while my Barrett-built engine appears to have been more efficient than the out-of-the-box Lycoming, I still had missions where 50 gallons just wasn’t enough. I would love to see 60 gallons on board, preferably in only two tanks so fuel management is simplified—you’d have five hours with an hour’s reserve at most cruise settings.

For passenger comfort, I’d love to see the rear cabin “poofed out” just a bit for more passenger room. The rear-facing seats in the second row are a big help to get passengers into the bigger part of the cone—and give them a better view of the outdoors—but you can’t really compare the back end of the Sportsman to a Cessna 182. Or even a 172. I would also move away from the folding wing and gain back some structural weight lost to the design. But both of these projects­—a new cage and a new fuselage shell—are probably not in the cards if they want to restart production in 2021.

That said, I was impressed with the current iteration of the airplane. Many of the details left to early builders and TWTT participants have been dealt with, and the quality of the finished product is very good. Now it’s up to Lervold and company to stop and assess what can be done with the design and implement those changes. The production pause allows them to concentrate on development.

If events such as worsening U.S./China economics (since the company is Chinese owned) and a prolonged pandemic mean that Glasair Aviation does not come back from this strategic pause, it’ll be a legit shame: The Sportsman really deserves to live on.


Let’s Talk Pricing

For the Two Weeks to Taxi program, Glasair Aviation built a base price that is highly inclusive, accounting for the engine, propeller, basic electronic instruments and radios, interior, wheels, brakes and tires—basically enough to have a completed, functional airplane, including the cost of the builder-assist program. That price is $244,500. From there, most builders have added upgrades. For example, the 180-hp Lycoming IO-360 (factory new engine) is included in the base price, but an upgrade to the 210-hp IO-390 adds $12,995. A 74-inch Hartzell metal constant-speed prop is standard, but there are upgrades to a larger metal prop, two- and three-blade composite props and even an MT option with reversing capability for floatplane use; these upgrades run $5995 to $21,750. Instrument panel options based on Garmin or Dynon/Advanced Flight Systems gear add capability and screen redundancy, and all include an autopilot that’s not part of the base price. Avionics package upgrades run from $14,995 to $27,495. There are myriad other upgrades (all visible on the company’s website, www.glasairaviation.com) that include rear-facing back seats ($4995), camera windows ($695 each), various landing-gear packages and upgrades ($495 to $4995) and paint upgrade options that run from $5500 to $9500 based on complexity. (The standard TWTT paint is a single color with vinyl stripes.) What if you want to build it yourself in the privacy of your own hangar? The Sportsman kit starts at a rather breathtaking $104,000, to which you can add $15,000 for the carbon-fiber option that nets a 150-pound increase in useful load. Glasair Aviation does, of course, offer engine packages, with the most popular being the Lycoming IO-390, a $55,395 hit that includes most of the FWF components, plug-and-play avionics packages ($40,395 to $79,995) and all of the options available to the TWTT models, albeit at slightly reduced prices since the builder will be installing them. The cost of the Sportsman kit is slightly obscured by the components included with it. For example, all the elements normally broken out as “quickbuild” are part of the kit; there are no “slow build” options. —M.C.

  1. I don’t quite get why anyone would spend that kind of money to build their own airplane. Seems like one already built and certified might be fine. Maybe a tad slower but the savings will buy a lot of fuel and how often do most people fly a light plane far enough that 25 kt more speed makes much difference especially since most of us fly for fun. If I have learned nothing else in 45 years of flying it is that you would love to squeeze 130 indicated out of your 172 or why won’t your Navajo do 200kt or your F-111 annoys you when it won’t break M 2.4. I am a curmudgeon maybe but assuredly an old analog guy.
