I thought that plane already had a RX in it?  You either bought it RTF (ready to fly) or as TX-R (which you would either have to buy an Any-Link to use any radio you wish via trainer port or have a Futaba or Tactic radio)?

If I am wrong...and there is a 3rd version that is "receiver ready", then I would be careful not to fly it too far out with a 6115 reciever.

With a 45" wingspan, you could be tempted to fly it further out than one normally would on a smaller plane or heli.  But long as you keep it close, I think you would be okay.
