For $39.99 for a wireless camera with a 300 foot range, you've wasted $39.99. The power output of that camera is too low to be useful for aerial video. Look in the Aerial Photography forum for a whole lot of advice regarding cameras, transmitters, high gain antenna, etc.

I tried a little higher end system a few years ago that was advertised good to 1000 ft line of site. I quickly discovered that the max distance is only under perfect conditions, stable platform, no vibration, etc. I've since upgraded to a higher power (1 W), and am planning on getting my FCC Technician license so I can legally operate it. I have FPV capability, but I still fly it within the AMA safety guidelines (line of site). Its cool, but if you don't spend the money, you'll be very disappointed with the results.
