Welcome to your weekly UAS News Update. We have four stories for you this week. First, DJI officially ends the Phantom line, SiFly releases the Q250 and Q12, more leaks surface about the potential DJI Mavic 4, and researchers develop a 'flying squirrel' drone with foldable wings.

first up this week, it's the end of an era for one of the most iconic drone series ever. DJI has officially announced the retirement of its Phantom 4 Pro and Phantom 4 Advanced drones. It set the standard for prosumer drones for years. It's a bit sad to see the Phantom line go, but technology marches on. We've seen DJI focus heavily on the Mavic, Air, and Mini series for consumers and prosumers, and the Matrice line for enterprise. So, while the Phantom might be taking its final flight into the sunset, its legacy in shaping our drone industry is undeniable. Pour one out for the Phantom!Next up, SiFly has released the Q12, a medium-sized, long-endurance aircraft. The Q12 offers a two-hour continuous hover, three-hour forward flight time, and 90-mile range while carrying a 10lb payload. SiFly also released the Q250, a heavy-lift drone with a 200lb payload and a 100-minute endurance. Both of these look like pretty cool drones with maybe the best flight times we've seen from a multi-rotor. Also, both drones are NDAA compliant, making them a possible replacement for those entities that require compliant aircraft. Specifics on battery, connection link, and available payloads aren't currently available. We'll keep you updated if we see more about the SiFly Q250 or the Q12!Now for another DJI story, the rumor mill is churning again, this time about the potential DJI Mavic 4. According to Jasper Ellens, the Mavic 4 is becoming, in his words, "the world's most leaked drone." Recent reports suggest leaked promotional images, potential pricing details, and even photos of the retail boxes have surfaced online. Now, take this all with a grain of salt, as these are just leaks. One particularly interesting tidbit is the mention of a possible new controller, the RC Pro 2, which might feature a vertical screen. A vertical screen could be interesting for how information is displayed, maybe better for certain types of flight data, or even social media integration, who knows? Along with the leaks, there was a list of supposedly cancelled features, including no Pro Res, no electronic ND filters at launch, and no RC Track, which, for those who may not remember, is the rumored tracking beacon.And last up this week, we have a cool research story out of South Korea. Researchers at Pohang University of Science and Technology, or POSTECH, have developed a drone inspired by flying squirrels! This isn't your typical quadcopter. It features foldable wings designed to give it significantly more agility, especially when it comes to braking or making sharp turns mid-air. You know how quadcopters can feel a bit floaty sometimes when stopping? The idea here is that these foldable wings can deploy rapidly to act like air brakes, allowing for much quicker deceleration than propellers alone can manage. This mimics how a flying squirrel uses its membranes to glide and maneuver. Or the ornithopter in Dune... While it's still in the research phase, this kind of bio-inspired design is fascinating. It pushes the boundaries beyond standard drone configurations and could potentially lead to drones that can navigate complex environments much more effectively. https://dronexl.co/2025/04/29/flying-squirrel-drone-foldable-wings/https://dronexl.co/2025/04/26/dji-mavic-4-canceled-features-rc-pro-2/https://dronexl.co/2025/04/27/drones-drop-super-clams-florida-indian-river/https://dronexl.co/2025/04/29/dji-phantom-4-takes-final-flight/
