4 hours on a single charge is an incredible engineering win for an ultra-light endurance rig, but that vibration battle tells the real story.

A father and son from South Africa have reclaimed the world drone speed record — their homemade quadcopter hit 657.6 km/h. YouTuber Luke Bell and his father Mike Bell set the record on December 11, 2025, in Cape Town. Their 3D-printed drone, Peregrine V4, achieved a record average speed over two runs in opposite directions — in line with Guinness World Records rules. The craft is powered by four modified 900 kV brushless motors, features optimized aerodynamics, and uses shortened propellers. The pair spent months refining the design, reworking nearly every component. This marks the third time the Bells have claimed the title of the world’s fastest quadcopter, each time beating their own previous records.

Built this 3D-printed VTOL fixed-wing aircraft from scratch. The airframe is made from ABS/ASA, reinforced with carbon fiber, and powered by an F405 flight controller with GPS-assisted flight modes. Seeing a pile of parts turn into a flying aircraft is always worth the effort. 🚁➡️✈️

❗️ArmyTV released an episode on the combat use of the German kamikaze drone HX-2 from Helsing. The approximately 12 kg aircraft carries a 2.5 kg warhead and is designed to strike armored vehicles, artillery, and fortified positions. Four electric motors enable speeds up to 220 km/h and a range of 100 km, combining vertical takeoff, high maneuverability, and rapid attack capability. A terminal guidance system reduces reliance on a stable communication link in the final flight phase.

🚨🇨🇳 PENTAGON IN PANIC: CHINA FLIES HEAVY DRONE WITH 1,900-KM RANGE AND VERTICAL TAKEOFF China’s 1.5-tonne Qizhi-5 heavy tiltrotor UAV completed an autonomous flight test at the Chuzhou test base on August 1, performing vertical takeoff, hover, transition into forward flight, manoeuvring and landing without requiring a runway. 🔸 The aircraft is designed to combine helicopter-style access with fixed-wing performance. Its stated specifications include a top speed of 450 km/h, a 300 kg payload and a maximum range of 1,900 km. 🔸 Power comes from the domestically developed CS35 modular turboshaft engine, rated at 350 kW. Its modular architecture is intended to simplify maintenance and allow the engine to support multiple aircraft types. 🔸 The most important part of the test was the autonomous transition between vertical and forward flight. During this phase, lift shifts from the rotors to the wings while the aircraft’s aerodynamics, controls and power demands change rapidly. 🔸 Completing the full sequence demonstrated that the airframe, propulsion system and flight-control software can operate together through the aircraft’s most technically demanding flight mode. 🔸 The developers say the programme has mastered six major areas: overall configuration, transmission, rotor design, flight control, structural engineering and aeroacoustic noise reduction. 🔸 Qizhi-5 is being promoted for cargo transport, surveillance, emergency response and other low-altitude operations. The same runway-independent design also offers clear value for military logistics, reconnaissance and operations from dispersed sites. The Qizhi-5 can lift vertically from a confined area and then travel at aircraft speeds across distances normally associated with fixed-wing drones. That combination gives China access to locations where conventional UAVs still need a runway. Which Qizhi-5 advantage matters most: vertical takeoff, 300 kg payload, 450 km/h speed or 1,900 km range?

First roadside drive for MOSS, the 3D printed open source litter picking robot. Tarmac, slopes, dry grass, fresh grass, the tracks go through all of it like a small bulldozer, nothing jams. Driven from the pad, straight from the battery switch, no laptop in the loop. Numbers from the onboard log: over 8 min of driving, over 70 m on each track by the encoders. Pack at 11.68 V at the start, 11.34 V at the stop, roughly 9% of the pack by the resting voltage afterwards. And only about half of the pack is usable before the tracks start stalling in pivots. The motors and the hardware in general held very well. Zero stall guard trips, zero dead pivots. The battery is the weak part, a $20 3S4P pack, 12 cells, sold as 40 Ah and clearly not. Charger and pack get replaced next. Rough estimate with proper high capacity cells: about 50 min and 430 m per charge.

MOSS the 3D printed open source litter picking robot on the beach for the first time. Tracks are well sized for sand: dry sand low dunes, damp sand and the waterline, no problem. The big dry dunes near the entrance are another story, the ground clearance is low and it got stuck twice. A quarter of the way down they get smaller and it passes without trouble. To take the big ones it would need a bigger robot or more ground clearance. It does not drive straight yet, I correct all the time, same as on the roadside video. That one is on me: the two tracks are not tensioned the same. Two tensioners per track, one sets the idler angle and the other the tension, and I only set them by eye after mounting. The encoders agree: on the road both motors turned the same within 1 %, so the drift is between the track and the ground, not in the motors. Battery: 12.1 V at switch-on, 11.8 V at rest back home. The 21700 cells are on their way. The rover was designed in Fusion with Codex in just a couple of weeks. OpenAI OpenAIDevs

Elon Musk just weaponized gravity. The entire trucking industry has a physics leak bleeding billions. Musk just sealed it. Most people look at the Tesla Semi and see a cleaner diesel. A truck that swapped a gas tank for a battery. That is a complete misread of the physics. Musk: “Let’s say you’re going over a mountain range. In a diesel truck, you actually don’t capture the energy of height or potential energy.” For a century, freight has fought gravity twice on every mountain. A diesel truck burns thousands of dollars in fuel clawing its way to the peak. It arrives at the summit loaded with enormous gravitational potential energy. And what does it do with that energy? It throws it away as heat. Musk: “You have to actually spend a lot of money on expensive brakes going down the other side so you don’t run out of control.” Diesel burns twice. Fuel going up. Hardware coming down. A century of logistics, and the descent was never anything but a cost to be survived. The Tesla Semi doesn’t survive the descent. It harvests it. Musk: “An electric semi truck is able to recapture the gravitational potential energy and in fact puts the energy back in the pack.” Regenerative braking doesn’t just slow the truck. It converts 80,000 pounds of downhill momentum into raw electricity flowing back into the battery. The mountain stops being an obstacle. It becomes a power plant. Here is the thermodynamic reality the market is missing. Diesel is closed on the descent. There is no version of a combustion engine that turns downhill momentum back into liquid fuel. It is structurally impossible. Electric is open in both directions. The same system that spends energy to climb gets paid on the way down. Wall Street keeps pricing the Tesla Semi on a cost-per-mile comparison. Kilowatts versus gallons. They are solving the wrong equation. You cannot win a price war against a machine that bills the planet for its own fuel.

The aircraft was not airworthy, not in the normal sense. A ferry flight is not a normal flight. The aircraft has a known defect that prevents it from carrying passengers. The defect cannot be repaired where the aircraft is, so it must be flown to a maintenance facility. It does not fly on a normal Certificate of Airworthiness. It flies under a Special Flight Permit: a one-time authorization that defines where the aircraft can fly, the crew required, and the operating limitations for that specific flight. I have been part of the process of preparing one of those permits. The defect is assessed. The risks are evaluated. The operating conditions are defined. The crew is fully briefed on the defect and its limitations. The route is planned around those limitations, and suitable alternate airports are selected. Then the aircraft departs, and you watch it leave, knowing exactly what condition it is in. That feeling stays with you. The permit exists because, in some cases, the safest option is to fly the aircraft under controlled conditions to a facility with the right people, tools, parts, and approvals, rather than attempt a repair where those resources are unavailable.
