Product overview
The Kimpok 1.2G 4W VTX is a wireless FPV video transmitter for racing-drone integration. Its nine selectable channels cover 1080MHz–1360MHz, with adjustable transmission settings of 25mW, 2000mW and 4000mW, plus Pit Mode. The hardware combines an aluminum alloy enclosure, heat sink and fan, with an SMA female antenna connection. Local buttons change band/channel and power, while separate red, blue and green LEDs indicate channel, band and power status. IRC Tramp provides a further control interface.
Installation requires space for a 53mm × 28.85mm × 16mm module, a 20mm × 20mm mounting pattern with 2mm holes, and ventilation around the cooling assembly. The six-pin connector carries supply power, grounds, video, IRC control and a 5V output; input power is DC 7V–36V with 2–8S battery support. Weight is specified inconsistently as 16g and 25.85g, without a configuration distinction. Above 100°C, protection progressively reduces output to 25mW; the original setting returns below 95°C. The antenna must be installed before power is applied.
