the mini but powerful 2.4G 500mw transmitter would make your fly to 3-4 km awasy with only the stock antenna, advanced build-in regulator offers this transmitter very wide power input range. I loved it so much and used this transmitter for over 1 year, it fits my "one battery on plane " theory very well! the dual av output on the unique receiver allows you to connect your goggle and possible recorder to the receiver at the same time.

your purchase will include:

transmitter, 3dbi stock antenna, av cable and power cable
