What transmitter power does Avatar in 2.4GHz mode? In 5.8dBm mode for FCC it is 33dBm, and 14dBm in CE mode. Not stated for 2.4MHz.

Nothing, it only transmits in 5.8GHz, is not a dual-band drone. You get 2W in FCC and only 0.025W in CE, so in Europe we are screwed unless we spend 40€ on the DH-Companion FCC hack.

Other dual-band DJI drones in Europe always choose to fly in the 2.4GHz band because it's limit power is 0.1W, wich is poor, but at least is usable.
