TS835 FPV 5.8G 600MW 48CH (2-6S) Wireless AV Transmitter is perfect for the small budget multi-rotor. A good little mod you can do is to simply solder a length of the single core wire to the SMA as this gives you more than enough range without the long hefty antenna. The RD945 various receiver is small in size for easy integration into your ground station, but large in quality and features.

 

There are two independent AV outputs for both audio and video. So user can use a monitor and a set of glasses or maybe a DVR to record their flight.Powering the receiver on the field is as easy as plugging in 3 Lipo cells into the included Prewired Mini JST cable.
