I have the Spektrum Dx3.0 radio and have already got three receivers bound to the transmitter which is all the memory allows anyway but i was wondering if i could bind a fourth receiver to it. I realise that i would have to set it up every time i want to use it and no settings will be saved etc, but that's ok as it's just a bashing truck so time isn't an issue.
If i can't do it that way is there a way of up grading the memory or something like that???

Hope i can sort it out as i don't want to have to go back to having two transmitters again.

Thanks
