With two dozen airplanes on one computer radio I decided it needed a transmitter redundancy plan. It hasn't gone completely smooth but I am getting there.

Thank you.  I would have rather not spent the money for a second transmitter but I sure would hate to not be able to fly during great flying weather.

TWO Spektrum transmitters? Isn't that just twice as bad as one?

I have a pair of Airtronics Stylus transmitters. I've copied stuff over like that. It was pretty easy, despite all the bells and whistles. I should see if I've got my pair of JR's copied.

If I had to select a 2.4 MHz radio system again this probably wouldn't be my first choice. I cannot say I have had a crash because of the system but smaller issues.

I have had trouble with the control sticks on two Spektrum radios. On the 6xi the elevator trim went out and on the DX9 a spring broke.
Service was quick and they did not charge me at all.

Trying to copy all the models from DX9 to the other one in one command did not work, it only copied 3. So I had to copy individually.

I like that I could purchase the radio from local hobby shop and additional receivers.

Sorry I didn't see this earlier. I have two DX5 (or DX5E?) transmitters. One thing I noticed right away was that range checks were just barely long enough to meet the spec. The first Radian disappeared after I looked away for a few seconds at medium altitude. I don't know if it suddenly dived or was lifted by a violent, invisible dust devil or what. So I got a second one, with a second transmitter. I managed to reach a tech support guy at Spektrum to ask about range problems. He told me that the receiver model I had was really for park flyers. This was a receiver supplied with the Radian! They sent me a different model number which seemed a bit better, but I eventually lost it, along with an entire model, not a Radian, when it stopped responding, well within visual range, and disappeared into a swamp. This is all DSM 2, mind you, and the DX5 has a bad reputation. Probably the new ones are much better, but I'm still holding a grudge.

I have an RDS8000 (Airtronics), which is a 2.4gHz radio much like an earlier model that was on 72 mHz. It's been very solid except for the time that a wire inside broke! Inspect the wires to the pots on a regular basis.
