I totally agree with Jester and Rodney. I would visit your local flying club and see how they might be able to help. For instance, if you showed up at my field: a) I would pull one of my 15 unused 72 Mhz Transmitters and/or Receivers, b) test your battery c) start and tune your engine and hook you up with a buddy-box cord. You would be flying within a few hours or less.

If your Transmitter or receiver batteries are dead, and can't find free or inexpensive radio gear, I would suggest migrating to an inexpensive 2.4Ghz radio like this one. http://www.horizonhobby.com/product/...ceiver-spm1000
I'm not sure if the combo listed included a Rx battery pack. These are about $20 http://www.horizonhobby.com/48v-1500...ttery-jsp91030
Feel free to ask as many questions as needed. If you want a free radio, PM me.
