Xponential Europe 2025 | Show report feature will allow operators to pause a video for up to 20 seconds, use their cursor to drag a box around a specified object, and then return the video to real-time. This feature only pauses the video for the operator, while the video continues streaming onboard, ensuring no loss of video integrity. “We are also continuing our developments on the counter-UAS side of things. For instance, based on requests, we can track up to 10 drones in a given video frame, and the next request is for up to 20 drones, so that’ll be what we release in that vein next, along with a new module update for enabling three video streams at once,” said Wehrman. MAD Components displayed a range of its newest products for UAV propulsion, paramount among them being its XP Series of drone arm solutions, each consisting of a connected electric motor and ESC pairing, pre-integrated on a carbon tube for turnkey installation into a multirotor hub. “We have designed our drone arms with agricultural spray UAVs in mind, and as well as being plug-and-play solutions, they integrate LED warning lights for working in night time or poor weather conditions,” says Jay Chen from MAD Components. The company’s XP6S Drone Arm Set is designed with an IPX6 protection rating, weighs roughly 766 g, and produces up to 12 kg of peak thrust (plus 3.5-5.5 kg continuous thrust). The system is suitable for integration on quadrotor UAVs weighing 14-20 kg with 5 litre fluid-tank payloads, or hexacopter UAVs weighing 21-33 kg and carrying 10 litres of payload. ElevonX unveiled the latest version of its Tango UAV with a wingspan of 4.4 m, enlarged from 3 m. “A key customer doing medical deliveries in Africa requested a UAV that could manage cargo transport missions over 100 km flight distances. That meant we needed to increase the size and weight of the fully electric version of the Tango aircraft to handle a bigger, doubled-up battery pack,” says Matej Meglic of ElevonX. Using the hybridised version of the Tango, incorporating a fuel engine as a range extender, would have increased the noise and maintenance requirements of the UAV beyond that customer’s tolerances, so staying all-electric was a strict requirement. Instead, the new Tango flies using a 12S battery pack with 60,000 mAh of energy. With the new updates, the batteryelectric Tango UAV can carry a payload of 5 kg over 100 km, drop it for the recipient and fly back over the 100 km distance with a safety margin of 27%. That is, the battery is expected to return to its original take-off point after 2.5 to three hours of flight with a 27% state of charge. Endurance can be increased further if some of the payload weight is dedicated to extra battery mass. “We do our own composite manufacturing in-house, so we thought that making the new wings would be simple – that turned out to be untrue,” Meglic says. “Creating and perfecting the wing took a lot of optimisation between weight, airfoil geometry, and its stability and efficiency in different airspeeds. We needed to make sure the aircraft could slow down in flight while dropping its payload and still switch back to high speeds, especially to get away from things like sudden weather hazards. “We started with CAD simulations, and then made sure to thoroughly test the iterations of the wing in many hours of real-life flight tests to ensure it worked for all air speeds.” 107 Uncrewed Systems Technology | April/May 2025 MAD Components’ XP6S integrated drone arm The full-electric variant of ElevonX’s Tango UAV (right) has been upgraded with larger wings for longer endurance (Image courtesy of Messe Düsseldorf)
