I've a chopper that can fly to good ranges (10~30m) and i am purchasing a video camera to install in it

Camera /transmitter spec. -
Button camera with audio +  1.2 ghz 500mw video transmitter (8x5x2) 130 g (my chopper can take this much weight with some modifications ).

Is it legal to use that AV Transmitter (1.2-1.3 frequency range 500mw power 3channels)

I'm buying it online from china , Is it possible to get this locally ? (this will cut off shipping)

any other thing that i must know before doing so?

You can ask him when it will be in stock.

Make sure the frequency of the radio isn't same as the frequency of the video transmitter.
