The Hacker HAES 90 is a Czech fixed-wing commercial/utility drone aimed at operators who need efficient forward-flight coverage rather than multirotor hovering. Based on the limited confirmed public data available, it offers 1 hour of endurance, 10 km range, a 90 km/h top speed, and a 2.4 m wingspan. That puts it on the radar for readers comparing survey, monitoring, and general enterprise UAV platforms, especially where fixed-wing efficiency matters more than vertical takeoff convenience. At the same time, many of the details that normally drive a real buying decision still need direct vendor confirmation, so this is best read as a careful market overview rather than a fully verified hands-on recommendation.
B-3 Review, Specs, Price, Features, Pros & Cons
B-3 is a Czech-origin fixed-wing military/ISR drone listed in the CNAS Drone Database, but the public record available in the supplied data is very limited. It is most relevant to defense researchers, institutional evaluators, and readers comparing fixed-wing surveillance-class UAVs rather than everyday drone buyers. What makes it notable is not a rich public spec sheet, but the fact that it appears as a named platform in a recognized drone reference source while many details remain unconfirmed.
