The runway is barely 400 feet long. It's covered in river stones the size of softballs and tucked into a narrow bend of an Alaskan canyon where the wind likes to swirl in unpredictable, nasty gusts. Most pilots would look at that strip and see a nightmare. But if you’re sitting in a Piper Super Cub, you just see a parking spot.
It’s honestly kind of ridiculous. We’re talking about a design that basically dates back to the late 1940s, yet it still outperforms million-dollar modern aircraft when the pavement ends. You’ve probably seen the videos of these planes landing on vertical ridgelines or taking off in the length of a driveway. It isn't just "bush pilot" magic. It’s the physics of a perfect airframe.
While the original J-3 Cub is the legend everyone recognizes for its yellow paint and open-door charm, the Piper Super Cub, or PA-18, is the one that actually does the heavy lifting. It’s the beefed-up, engine-swapped, ruggedized evolution that turned a flight school trainer into the ultimate mountain goat of the skies.
What Actually Makes a Piper Super Cub Different?
People get the J-3 and the PA-18 mixed up all the time. Don’t.
The J-3 is a 65-horsepower toy. It’s lovely, but you have to fly it from the back seat when you’re solo just to keep the center of gravity from getting wonky. The Super Cub changed the game by moving the pilot to the front seat, adding electrical systems, and most importantly, throwing a lot more muscle under the cowl. Early models started with 90 hp, but the sweet spot—the version everyone wants—is the 150 hp or 160 hp Lycoming O-320 variant.
Think about that power-to-weight ratio. You have an airframe that weighs about 1,000 pounds empty being pushed by 150 horses. It’s like putting a Hemi in a go-kart.

The wing is the secret sauce. Piper added flaps to the Super Cub, which the original J-3 lacked. These aren't just for show. They allow the plane to fly incredibly slow—we’re talking 38 to 43 mph—without falling out of the sky. When you can fly that slowly, your landing distance shrinks to nothing. You touch down, hop over a few rocks, and you're stopped before you can even exhale.
The Obsession with Modifications
If you see a "stock" Super Cub today, it’s basically a museum piece. Real-world owners treat these planes like Jeep Wranglers. They are never truly finished.
The first thing almost everyone does is swap the tires. You’ll see these massive, 35-inch balloon tires—often called "Bushwheels"—that look like they belong on a monster truck. They aren't just for the aesthetic. These tires act as the primary suspension. Since the Super Cub uses a simple bungee-cord gear system, those low-pressure tires soak up the impact of a rocky riverbed so the airframe doesn't snap in half.
Then there are the "VG" kits. Vortex Generators. They’re these tiny little metal fins stuck along the top of the wing. They look like nothing. They cost a few hundred bucks. But they re-energize the airflow over the wing at high angles of attack, allowing you to keep control even when you're hanging on the prop at speeds that would make a Cessna 172 spin into the ground.
- Borer Propellers: Long, flat-pitched props designed for maximum "pull" rather than top speed. It's like putting your truck in 4-Low.
- Square Wings: Some builders clip the rounded ends and make them square to increase lift surface.
- Extended Baggage: Because if you’re going into the woods, you’re bringing a tent, a rifle, and probably a cooler.
Why Not Just Buy a New Plane?
You'd think that in 2026, with all our carbon fiber and glass cockpits, the Super Cub would be obsolete. It’s not. Not even close.

Carbon Cub and other modern clones from companies like CubCrafters are incredible. They use lighter materials and even bigger engines (some pushing 180-210 hp). They are technically "better" by every metric on paper. Yet, the original Piper Super Cub holds its value like gold. A well-maintained PA-18 can easily fetch $150,000 to $250,000.
There's a ruggedness to the steel tube fuselage that’s hard to beat. If you bend a steel tube in the middle of nowhere, a guy with a welder can probably get you home. If you crack a high-tech carbon fiber spar in the Alaskan bush? You’re in for a very expensive helicopter ride to recover the wreckage.
Also, the flight characteristics are just... honest. There's no flight computer helping you. It's just cables, pulleys, and your feet on the rudder pedals. You feel every bump in the air. You feel the wing start to buffet right before it stalls. It’s a physical conversation between the pilot and the wind.
The Reality of Owning One
It isn't all sunset flights and gravel bars.
Owning a Piper Super Cub is a commitment. Most of them are "tube and fabric." That means the skeleton is steel, but the skin is literally fabric—usually Ceconite or Poly-Fiber. It’s incredibly light and strong, but it doesn't last forever. If you leave it outside in the sun for ten years, the fabric will degrade. You have to "punch" the fabric during annual inspections to make sure it’s still strong enough to hold the air.

And then there's the ground looping.
The Super Cub is a taildragger. This means the center of gravity is behind the main wheels. If you let the plane swerve too far on the runway during landing, the back end wants to come around to the front. It happens fast. One second you're landing, the next you're doing a 360-degree spin and dragging a wingtip. It’s the number one reason these planes get wrecked.
How to Get Into the Cub Life
If you’ve got the itch to fly one, don't just go buy one. That's a recipe for a very expensive insurance claim.
- Find a Tailwheel Instructor: You need a specific endorsement to fly these. Find an instructor who specializes in "stick and rudder" flying, not just someone who teaches in a nosewheel Cessna.
- Rent Before You Buy: Many flight schools near mountainous regions keep a Super Cub or a Husky (its younger, faster rival) on the line. Spend ten hours in one. See if you actually like the cramped cabin and the smell of aviation fuel.
- Check the Logs: When you eventually look at a listing, ignore the paint. Look at the engine times and the date of the last "re-cover." A fresh coat of fabric is worth its weight in gold.
- Join the Community: The SuperCub.org forums are a rabbit hole of tribal knowledge. Those guys have forgotten more about Lycoming engines than most mechanics will ever know.
The Super Cub isn't a cross-country machine. It’s slow. It’s loud. It’s drafty. If you want to fly from New York to Florida, get a Cirrus. But if you want to see the parts of the world that don't have roads—the places where the mountain goats look at you with confusion—there is simply no substitute for this old Piper.
It’s been 75 years and we still haven't found a better way to land on a riverbank. That tells you everything you need to know.
