Heart Aerospace X1 takes flight as the world’s largest battery-electric aircraft

Posted on by

Electric aviation has reached a milestone that once seemed reserved for much smaller aircraft. Heart Aerospace’s X1 demonstrator has completed its first flight, becoming the largest battery-electric aircraft ever to take to the skies. The aircraft flew from Plattsburgh International Airport in upstate New York on August 12, marking a significant step toward bringing electric propulsion to the scale of regional air travel.

The X1 is not intended to become a passenger aircraft itself. Instead, it is a full-scale technology demonstrator for Heart Aerospace’s ES-30, a 30-seat hybrid-electric regional aircraft currently under development. Its purpose is to validate the propulsion system, aerodynamics, flight performance, and other technologies that will eventually be carried into the production aircraft.

Designer: Heart Aerospace

For a prototype, the X1 is quite substantial. It has a 106-foot wingspan, measures 76 feet from nose to tail, and weighs more than 25,000 pounds at takeoff. Four electric motors provide propulsion, drawing their energy entirely from onboard batteries during the test flight. The maiden flight lasted 27 minutes and included taxiing, takeoff, climb, maneuvering, and landing. The aircraft reached 1,100 feet above ground while its electric propulsion system delivered more than one megawatt of power. The test was conducted under an FAA Special Airworthiness Certificate in the Experimental Category, with the flight kept within a controlled test envelope.

Perhaps the most striking detail is the reported energy cost. Heart Aerospace says the flight used approximately $5 worth of electricity. That figure covers the battery-powered flight operation, while some reporting notes that electricity consumed during ground taxiing would need to be considered separately. Even with that distinction, the demonstration offers a tangible illustration of the potential operating-cost advantage of electric propulsion over conventional aircraft fuel.

The limitations, though, have still to be kept in mind, as batteries still cannot provide the energy density required for longer regional flights. That is why the production ES-30 will use a hybrid-electric architecture rather than relying entirely on batteries. Heart Aerospace is targeting an all-electric range of about 124–125 miles, while hybrid operation is expected to extend the range to roughly 497–500 miles. The aircraft is designed to carry 30 passengers and has a battery recharge time of around 30 minutes.

Heart expects the ES-30 to reduce operating costs by more than 40 percent compared with legacy regional aircraft, combining lower energy costs with simpler electric propulsion, reduced maintenance requirements, and potentially greater reliability and aircraft availability. Airlines including United Airlines and Air Canada have committed to the program, with total customer commitments reported at $9.4 billion.

The first pre-production ES-30 is already being developed at Heart Aerospace’s Los Angeles pilot manufacturing plant, with flight testing scheduled for 2028 and entry into service targeted for 2031. The X1’s 27-minute flight does not make electric commercial aviation a finished proposition, but it unearths something more fundamental. Battery-powered propulsion can now lift an aircraft approaching regional-airliner scale off a runway and enable a controlled flight. That is a feat in itself!

This $99 Trackball Has Gesture Controls That Work Without Any Software

Posted on by

The computer peripheral market has always been more experimental at its edges than in the mainstream. Ergonomic trackballs, in particular, have attracted a devoted following among power users, but the options tend to cluster at two extremes: consumer-facing products with locked-down firmware, and niche open-source hardware that trades polished finish for deep customizability. Finding something that genuinely does both has rarely been straightforward.

Ploopy’s Adept trackball made a compelling case for the latter category, earning a loyal following with its open-source, 3D-printed design and QMK compatibility. But it always felt like it had more to say. Its circuit board had always reserved space for two more switches that never made it to production, and the base had slots for a wrist rest that never materialized. The A+ is that unfinished story, now finished.

Designer: Ploopy

The most visible addition is the button count. The Adept had six; the A+ has eight, two of which also function as knobs. Out of the box, the knobs handle high-resolution vertical and horizontal scrolling, but both are fully reprogrammable for other functions. That dual-purpose approach keeps navigation and control within a single hand without needing a separate scroll wheel or accessory sitting alongside it.

The gesture system is arguably the more interesting addition. Hold a button and flick the ball in any of eight directions, and the device fires a command. By default, the left knob activates cut, copy, paste, desktop switching, and media controls. For someone who lives inside a browser and a text editor all day, that’s a significant amount of functionality without ever lifting a hand off the device.

Layers add another dimension. The A+ has two: a navigation layer for everyday use and a control layer accessed via the right knob. The control layer handles on-device configuration, covering left-hand mode switching, toggling between high-resolution and stepped scrolling, and other adjustments. It’s the first trackball to bring this kind of layered behavior, working entirely without any software running on the host computer. There are also two bright LEDs that can be used to visually tell you what layer you’re on without having to rely on some embedded screen.

The detachable wrist rest is another long-promised feature that finally arrives with the A+. It slots in or out during use and can be screwed on permanently if preferred. The device stays ambidextrous throughout, and its 3D-printed shell means the community can print modified bodies, alter the layout, or swap in custom colors. That kind of adaptability isn’t an afterthought; it’s part of how the whole thing is designed.

The Pixart PMW-3360 sensor carries over from the Adept, running at a 1,000Hz polling rate with the tracking accuracy that has made it a standard for performance-oriented pointing devices. Omron D2LS-21 switches handle the physical buttons. The firmware remains QMK, configurable through VIA, with all design files, firmware, and assembly instructions freely available on GitHub. Kits start at $99 CAD.
