Hi,
right, that's like with every 2.4 GHz system. You can bind multiple receivers to one radio, but only one radio to one particular receiver.
Swapping is of course possible (bind and fly, no matter which stick mode or switch configuration, just do a pre-flight the first time to confirm everything works as advertised, especially Rescue or Nitro specific switches (kill/throttle cut), if you have never flown Rescue or Nitro with a particular radio.
Same goes for special functions using macrocells, familiarise yourself with the switch assignments (option switches), check for doubles, set up properly if necessary.
You can also buddy box, with two VBar Controls: just switch on/bind the primary radio, then switch on the secondary radio, go to the buddy box menu, and go to the bind menu again on the primary radio, to bind the buddy radio into the network.
So many options
and yet so simple.
Cheers
