While hunting the china rc market I found a super cheap 9ch radio.  One draw back is no rechargeable batteries, no biggie.  Not very difficult to bind the receiver,  just had to hunt on u tube for info. Only issue I had was is said switch error when I first turned it.  I found out all the switches have to be in certain position for the radio to work.    Also I found a 6ch computer radio on same site.  It's a real computer radio, because u have to hook it to a USB port (with provided cord) and do setup on the provided program.  Not bad for price, but with out a lot rc radio I would stay away from these radios.
