3DR 433MHz Telemetry Radio Set, 1000mW High-Power, 2-3km Data Range

The standard 3DR 433MHz telemetry radio runs at 500mW, which covers most close-to-mid-range flights comfortably - but a survey mission flown further out, or a build with a less favourable antenna placement, can eat into that margin fast. This 1000mW version doubles the output power, stretching the usable data range to roughly 2-3km and giving a genuine buffer against the kind of signal dropout that a standard-power radio would start to struggle with at the edge of its range. Still speaks the same open MAVLink protocol as every other 3DR-family radio, so it drops straight into an existing APM or Pixhawk telemetry setup.
