I want to get a sense of what is maximum amount of power I can use for a 900mhz video transmitter mounted to the Phantom 2 (non-vision). I've seen some videos on YouTube of 800mw being used. But, has anyone gone higher than that (e.g. 1000mw or 1500mw) on a Phantom 2? I don't want to introduce radio interference with the 2.4ghz radio control. Thanks!
