Check out the JR6102 radio. It's a very nice radio and less expensive. Find it at www.jrradios.com. You can also look at the Spektrum DX6, but it's features are limited.

I also use the JR 770 PCM receiver in my Rex with a JR8103 Tx and they are great. The JR6102 can be puchased with the 770 PCM Rx if you choose, the 700 and 610UL are also terrific Rx's. I have them all and have never had a glitch with any of them. I prefer PCM on helis though.
