>its high torque, available over a magnificently wide band of motor speeds
A broad torque curve isn't really useful since aircraft engines are already optimized for sustained operation at cruising speed and the range of speeds you can operate at is limited by the propeller and physics. There's no need to have a ton of torque at 1800rpm and at 6000rpm
>At 20 kilograms (45 pounds), the motor can be held in two hands, and it measures only 10 centimeters deep and 30 cm in diameter
And what's the horsepower rating and duty cycle rating on this motor? Power density is not an area where electric motors have a large advantage over ICE unless you're trying to build a cylindrical package. The article talks about doing away with durability requirements that impede a lightweight design.
>with no power-sapping transmission
Most small aircraft are direct drive.
Electric power certainly has advantages but this article may as well be a marketing brochure full of fluff.
