Welcome to your weekly UAS News Update. We have four stories for you this week. First, the DJI Mavic 4 Pro's launch date, specs, and pricing have been leaked. Second, a research team developed a battery that lets drones fly in extreme cold. Third, a missing woman in Wisconsin was found quickly, thanks to a drone. And finally, President Trump nominates a new FAA Administrator.

And first up this week, we have exciting leaked information about the DJI Mavic 4 Pro. According to sources, the drone is set to launch on Thursday, April 24th, 2025. Expect an official teaser from DJI around April 17th. This is pretty much in line with previous leaks, giving us confidence in this date.The Mavic 4 Pro will boast three cameras with focal lengths of 28mm, 70mm, and 168mm. That's 2.5x and 6x which is slightly different from the current 3x/7x configuration. It will reportedly record in 6K, with a larger sensor than the Mavic 3, promising even better image quality. The gimbal is getting a major redesign, with 360-degree multidirectional movement. An unexpected feature... The Mavic 4 Pro will reportedly feature an electronic ND filter system so no more carrying ND filters around. If that is true, I will be impressed!DJI is claiming a flight time of 52 minutes. As far as charging: three batteries in only 90 minutes, aligning with the leaked 240W charger specs. And it looks like a new controller is coming – the DJI RC Pro 2, featuring a 7-inch tilting touchscreen.Price-wise, the leaks suggest the Mavic 4 Pro with the DJI RC2 will be $2,250. The Fly More Combo with the RC2 is priced at $3,200. And the top-tier 512GB Creator Combo, including the new DJI RC Pro 2 Controller, will cost you $4,400. Next up, a research team from the Dalian Institute of Chemical Physics has made a breakthrough in battery technology. They've successfully flown a hexacopter drone in temperatures as low as -32.8 degrees Fahrenheit, or -36 degrees Celsius. This is a big deal because standard lithium-ion batteries struggle in extreme cold, often losing 30% to 50% of their capacity.This new battery, however, retains over 90% of its nominal capacity at -40 degrees Fahrenheit, with endurance loss under 10%. Beyond drones, this tech could also benefit electric vehicles and remote power stations.And in our third story, a real-world drones-for-good story! In Wisconsin Rapids, Wisconsin, a 59-year-old woman was quickly located by a drone after ground searches failed. She had been outdoors for about three hours and was unable to stand. Rescuers reached her within one minute of detection, just before a storm rolled in. The interesting part here is that the Wisconsin Rapids Police Department didn't own the drone. They relied on Wings of Hope, a non-profit organization. This highlights the financial challenges many smaller departments face in acquiring this life-saving technology. As we see affordable drones becoming harder to get because of regulation, this might prevent small departments from getting ANY drones at all.Finally, this week, the White House nominated Bryan Bedford, CEO of Republic Airways, to head the Federal Aviation Administration. Bedford, a pilot with over 30 years of experience, faces significant challenges if confirmed. These include decisions on Boeing 737 MAX production, approval of new 737 variants, and addressing a shortage of approximately 3,500 air traffic controllers.https://dronexl.co/2025/03/19/dji-mavic-4-pro-launch-date-features-prices/https://dronexl.co/2025/03/17/chinas-breakthrough-battery-powers-drone/https://dronexl.co/2025/03/17/drone-missing-woman-wisconsin-rapids/https://transportation.house.gov/news/documentsingle.aspx?DocumentID=408316#:~:text=Joint%20statement%20of%20Transportation%20and,Administrator%20of%20the%20Federal%20Aviation
