Fixed-wing planes and helicopters are no longer the darling of the RC world. Even quadcopters and other multirotors are starting to look old hat, as the community looks to ever more outrageous designs. [rctestflight] has slimmed things down to the extreme with this coaxial bicopter build, also known as the Flying Stick (Youtube video, embedded below).

The initial design consists of two brushless outrunner motors fitted with props, rotating in opposite directions to cancel out their respective torques. Each is mounted on a gimbal, setup to provide control authority. iNav is used as a flight controller, chosen due to its versatile motor mixing settings. The craft was built to test its ability at recovery from freefall, as a follow-on from earlier attempts at building a brushless “rocket” craft.

A “spaceplane” that will be able to travel at 25 times the speed just reached a major breakthrough.

Reaction Engines is working with the European Space Agency and the UK Space Agency to develop a hypersonic aircraft that could zip from New York to London in just one hour.

The British aerospace manufacturer has tested the an essential piece of equipment called a precooler, which prevents the plane’s engine from overheating.

London to Sydney in 4 hours, anyone?

In 2013, Lockheed Martin announced development of the successor to the SR-71 Blackbird spy plane.

The SR-71 was capable of reaching speeds over three times the speed of sound, and the SR-72 is intended to have even more impressive specs. Following is a transcript of the video.

“One of the biggest roadblocks to generating functional tissue replacements has been our inability to print the complex vasculature that can supply nutrients to densely populated tissues,” said Jordan Miller, assistant professor at Rice University in the US.

“Further, our organs actually contain independent vascular networks — like the airways and blood vessels of the lung or the bile ducts and blood vessels in the liver,” Miller said.

“These interpenetrating networks are physically and biochemically entangled, and the architecture itself is intimately related to tissue function. Ours is the first bioprinting technology that addresses the challenge of multi vascularisation in a direct and comprehensive way,” he said.

A cataclysmic collision between a pair of dead stars may have seeded our solar system with precious heavy metals including gold and uranium, according to a newly published study. If such an event were to be observed in the present day, it would be the brightest point in the night sky.

BAE Systems has made aviation history by maneuvering the first aircraft in flight using supersonically blown air instead of ailerons or other control surfaces. Taking to the skies over Wales, the wing-shaped Magma UAV makes use of two new technologies that could revolutionize aircraft design.
