RE: JR reciever
I am currently using the Spektrum 2.4 Module with my XP9303, but I have also used it with my XP8103 for a couple of years. You do not have use of the Model Match feature that you get with the X9303 or the Spektrum radios, but I think you can purchase it, now, for $109, with a 2.4 Rx. It works great.
