Diatone Roma F4 LR: Long-Range on 4 inches

For years, long-range drones were associated with big and purpose build (mainly lightweight) quadcopters. With at least 7-inch propellers, but true long-range started at 8-inches or more. Times changed, and in the 2020, a new class of long-range FPV quadcopters emerged: light, dead-cat frame, 4-inch propellers, weight around 250g, and with flight times somewhere between regular cruisers and purpose build long-range machines. Sure, they are not capable of going as far as "true long-range," but far enough that majority of pilots consider them build for distance.
