Quiet, roomy, and fuel efficient:  Synergy is a new class of airplane.

A Remarkable Breakthrough

Synergy_wideSynergy is an airplane designed to safely fly one to six people directly from town to town, in less time and at less cost than airliners or automobiles. Its innovative technologies deliver the first sustainable  economics for transportation in the speed range between the supercar and the airliner.

Right now there aren’t any economical and efficient personal airplanes with the kind of seating, payload, and go-anywhere utility to compete with the family automobile. This is because no previous planes have used Synergy’s systematic approach to reducing the energy cost of regional flight. Yet the same proven principles of advanced fluid physics that give Synergy its exceptional stability, speed, and control (through drag reduction!) also make it comfortable, compact, and safer, thanks to stall resistance and low speed landings.

Synergy Aircraft is beginning the transition from project to product development as we work to complete the full-scale aircraft prototype well underway.

We believe that building simple aircraft on the right foundations -both in business and design- will make the case for smarter investment in transportation.

Thanks to Synergy, group travel in our comfortable, affordable smartplanes™ would be faster and more economical than any other form of regional transportation.

At Synergy Aircraft, we understand that for personal airplanes to reconnect with their potential customers, or realize their potential benefit to society, they must provide:

  • Greatly reduced travel time.
  • True passenger safety.
  • Far lower price.
  • Quiet, neighborhood manners.
  • Adaptability to hybrid, electric, and other advanced engine technologies.
  • A more spacious cabin.
  • A quiet, smooth ride.
  • Far greater economy, using common fuels.
  • Easier operation.

Synergy is the first and only aircraft designed to achieve all of these benefits, by working the entire problem at once: fundamental flight physics, human factors, and industrial economics.

Synergy Prime: Fundamentals First

Synergy in flightSomething known since the 1950s, yet hardly acknowledged, is that all prior aircraft waste enormous amounts of energy to fly in the mid-subsonic speed range. The problem is aerodynamic drag. Through its comprehensive, patented design, Synergy is the first aircraft to apply six of the most advanced drag reduction technologies.

The first key is its distinctive “double boxtail™” wing-becomes-tail configuration, which provides outstanding stability and control while reducing the dominant cause of drag at low speeds,  called “induced drag”.  Unlike boxwing designs, the twin horizontal tails -above and behind each wingtip- aren’t ‘wings’ to make more lift. In fact, these control surfaces actually create a downward force most of the time. This downward force (the right amount, in the right place) acts against the ‘induced drag’ so well that it actually reduces the total drag, a lot like a sailplane reduces its total drag by adding wingspan.  Some think of it like origami: folding up the low-drag airfoil surfaces of a long wing in 3-D space, so as to achieve stable, high-speed flight while carrying a lot more useful load than a glider.

But that’s just the beginning. Synergy’s unique configuration unlocks the door to important high-speed drag reduction technologies, such as laminar flow, pressure thrust, and powered drag reduction. In short, Synergy uses its ‘high span efficiency’ and lightweight structure to reach speeds where its ‘passive and active drag reduction’ pays off in major efficiency gains. It then adds a fuel-sipping, turbocharged jet-fuel engine, a ballistic parachute, and next-generation smartplane electronics.

Synergy brings the right innovations to make direct, on-demand regional travel a financially sustainable reality. At mere pennies per passenger-mile, and with a design able to scale into low cost mass production, the potential for this quiet, roomy, comfortable aircraft and its progeny challenges society itself: to respond correctly to an unprecedented, unfulfilled latent demand.

To steward such a potentially profound innovation safely toward broad adoption, Synergy founder John McGinnis proposed a far-reaching plan that has been continually refined since before the actual design work even began. To help offset the technology risk, more than a thousand Team Synergy volunteers and financial supporters from around the world united behind John and his small team of visionary partners to help build the prototype Double Boxtail™ aircraft… starting, naturally, in his father’s garage!

This grassroots effort permitted thousands of engineering challenges to be met without the risks and distractions brought by typical premature business hoopla. Our new facilities and investment allow us to continue building that momentum. Once the completed prototype allows us to make our case fully public, Synergy Aircraft will reveal a team and a plan of the same caliber as their then-proven product technology, and begin working with industry to make history.

It’s been more than a lifetime since aviation captured our collective attention. It will take a long term effort, in well managed phases, to return it to health… not just the usual well-connected capital and promotion. Making it possible in this case is a product concept with the required demand and profitability to reward large scale investment at each level of adoption, and a tenacious, inspiring vision. We invite your interest with appreciation.

General Aviation, the Next Generation

Fuel Efficient

Synergy is three times more fuel efficient than most General Aviation aircraft.


Synergy uses brilliant physics to achieve twice the expected speed for a given horsepower.


Due to its turbocharged rear engine, laminar-flow aerodynamics, and submarine-like tail fan, Synergy is far quieter than other aircraft.


Synergy has a spacious six-seat interior, yet a smaller exterior size than a two-seat trainer.

I Support You!

How on EARTH are you doing this?

Designing and building a completely new aircraft prototype from scratch is expensive. Far too expensive, in fact, to offer reasonable investor risk when done as a cash-burning business adventure from the very beginning. But not nearly so expensive when done as a family project, by an amazing group of people who’ve made themselves TEAM SYNERGY. They would change the world, for lunch with like-minded visionaries. Join the movement and the Wall of Fame by supporting Team Synergy volunteers with your generous donation of any size.
