DO not use a JR anything with a futaba anything because they will not work well and most likely cause a crash unless they are made to use together, Hitec makes recievers for both and they also make some pretty good radios too, I now use exclusively JR (8103 I love this thing) A place you could take a look is servocity.com http://www.servocity.com/ServoCity/index.html
They have good prices and free shipping. Let us know what you decide to do.
