I put a CB200 setup in one of my planes early this year and have been flying it with no perceived issues either while flying or viewing the telemetry. The CB200 as well as the standard receivers have been this way the whole time with very few issues as I understand it. It demonstrates that the backup receivers may not be as necessary as we all think they are. Obviously they aren’t or planes would be falling out of the sky. My current build i had planned a REX12A with a R3 as a second RX. But now I’m wondering if I even bother with the R3. I already have another R3 acting as a remote switch for the DSM10. . Maybe I just go with the REX12A and the R3 as the switch and call it good.

Don’t get me wrong when the firmware update or the new CB2XX comes out I’ll be looking to to update... but really, at least in my flying environment/installations the second RX doesn’t appear necessary.
