Well David and Daniel... A mix of both your ideas together. I used Davids idea for getting Rx1 to bind by selecting other model and then back to the model to bind. I got Rx1 to bind right away. But during the whole time the hour glass was on for the Rx2. I then turned off Tx and did it all over again, but the Rx2 wouldn't bind. So, I got a little pissed to be honest, and pressed the "bind secondary" button like 3 times really fast, and for some reason, it bound. Crazy and not really comfortable with all this. Then I went explorer to set up each RX and see the CB200, I found it odd that the CB200 showed up on Rx2. normally it's on rx1. so I went to connect to Rx1 and couldn't. had to rebind rx1 and now fine... So... yes, I got it to work, but that all a little scary for 5 figure models.... Let's see if ZB will chime in. I'd be more than happy to find out I'm doing something wrong.
