Back before Blade Runner captured our imaginations, sci-fi writer Ray Bradbury envisioned small personal helicopters that people would use to commute around the cities of the future. Well, the Janus-1 is just such a beast, and it may someday be yours … emphasis on "may be."

Currently being developed by Chinese startup X-Control, the single-passenger Janus-1 already exists in fully-functional prototype form.

And while the company describes it as a VTOL (vertical take-off and landing) aircraft, the thing is really just a little, folding, modular, tandem-rotor helicopter. Owning one would be kind of like having a very scaled-down Boeing Chinook helicopter that you could stick in the back of your car, or store in your garage.

What's more, while virtually all VTOLs being developed these days are electric, the Janus-1 is powered by a turboshaft engine that gulps n' burns diesel, kerosene or Jet A fuel. That engine takes the copter to a cruising speed of a 62 mph (100 km/h). One fill of the 5-gallon (19-liter) fuel tank should be good for about 30 minutes of flight time.

The Janus-1 is claimed to tip the scales at 595 lb (270 kg) and can manage a passenger/cargo weight of up to 440 lb (200 kg).

It's rated to a maximum altitude of 19,685 ft (6,000 m) and can be either manually or autonomously piloted. In either case, X-Control states that because the flight controls are so simple and the aircraft is so small, a pilot's license is not required to fly it.

Along with its use as a personal commuter, possible other applications for the Janus-1 include cargo transport, emergency medical response, aerial surveying, and wilderness rescue. Importantly, its folding carbon fiber cockpit can be swapped out for other modules depending on intended usage, and if the aircraft is in autonomous flight mode, it doesn't even need to have a pilot on board.

We've reached out to X-Control regarding pricing and availability of the Janus-1, but have yet to hear back. In the meantime, here's the helicopter in flight.

UPDATE (Oct. 30/25): X-Control has informed us that the Janus-1 is now commercially available, priced at US$249,800 for a fully-assembled aircraft or $219,800 for a kit that buyers assemble themselves – those prices don't include shipping.

One thing that got me right off is how close to the engine the pilot's head is. I hope that the headphones are excellent at sound mitigation.

Had me all excited with it flying over Albert Park Lake in Melbourne, before reading the caption that it was an artist rendering. The chances of any state or federal government in charge in Australia of ever allowing these into the city skies with an unlicensed pilot and a fully-insured and registered craft (thus making this unaffordable for those it is intended to help) any time soon are diddlysquat.

Can it actually land & take off on water? Can those pontoons double as storage? Must be patient when getting out and let those rotors stop completely...

Seems as practical as it gets, leveraging existing technologies and designs instead of some fancy multi-rotor and battery electric. It has proven safety or risk abatement in the known configuration (rotors on top, dual, etc.). Costs should be super low. Then let’s see how alternative configurations or newer power source can improve on it.

I has the same range and performance as its electric counterparts so it better be less expensive. Still. it's pretty cool.

Looking at the video they seem to have done a good job of miniaturizing a tandem-rotor.
It will be interesting to see how reliable the drivetrain will be. Looking at the videos on their webstie, there seems to be a drive axle running between the front and rear rotor. That means there should be at least three gearboxes. Two right-angle boxes for the rotors and one gearbox to reduce the turbine speed to something that the rotors can handle. If any of those fails, the craft will be in serious trouble.
If I was a regulatory body, I would at least like to see engine-out landings from different altitudes and velocities succesfully demonstrated before thinking about giving this thing a permit.

Great picture of a gentleman carrying what appears to be the motor, etc. Maybe I'm just a weakling, but how does one stick a 270kg piece of gear into the back of a car?

Yes a bicopter was the first way down the road to Hover at any attitude flying platforms, manned or unmanned. ( As soon as it has a crew it is an aircraft, not a drone in any way the word could be used. In the modern world anything can be remotely controlled with minimal additional hardware ( it only requires a radio link rather than a wired link to the fly by wire or manual actuation system.)
If this has full swashplate control( collective+cyclic of both rotors, it could be a phenomenally adaptable platform. ( The magic is fairly simple just a couple of angle drives off a propulsion system then the swashplate control to the rotor head, Electronic/microcontroller applications make it relatively simple to control..)

Are people unaware of or just ignoring how incredibly loud any rotary blade flight actually is?
