So...



RTF (ready to fly) units sold from Spektrum aren't really meant to bind to other units. It's kind of a "one shot, this unit only" type of situation. It *IS* possible to make it bind, to something else, but it's limited to only 4 channels.



What I would recommend is what others have suggested - purchase a Spektrum transmitter, or a DSMX programmable transmitter. The DXe transmitter is the cheapest one out there at $60, but it's pretty watered down in functionality. That said, you can have, in theory, an unlimited amount of models that you can bind to it; however, you can only bind one at a time and have to store the models in a computer or smartphone/tablet that you have to load to the DXe each time you want to change to a new aircraft. That's the major downside of this method. Upside of the radio, it's inexpensive, it has wireless trainer capabilities, and it's a 6 channel radio.



If you want to step up to something that can store models, either the DX6 or DX6e are better choices. However, they range from $150-$200, depending on the model. The DX6e lacks diversity antennas, which means that it's not as reliable in signal as the DX6 (but is usually still plenty of signal strength to cover an average baseball or soccer field), and it lacks voice alerts, which means it can't talk to you and tell you that you have a minute of flight time left. The pro for the DX6e is that it's $50 cheaper than the DX6.



Receivers for the Spektrum are just as inexpensive as the receiver you looked at. OrangeRX and Lemon RX tend to be about $15 each, and sometimes you can pick up OrangeRX DSMX 6 channel receivers from HobbyKing on sale (my dad got 5 for $25 about a year back). Actual Spektrum brand receivers seem to run about $25 and up, depending on how many channels you need (the new Sport receivers for 4 channel start at $30, but I've bought older 4 channel Spektrum branded receivers at my hobby shop for $25 before I found out about the Lemon and OrangeRX brands).



If you are going to go Spektrum, I'd point towards the DX6 - it's a well made receiver, the controls are solid, and the voice alerts speaking the time are a lot nicer than a couple of beeps that are warning you. And, the diversity signal strength is a nice bit of insurance against loss of signal. There ARE cheaper options in the Spektrum family, and if you really want to get dirt cheap, you can go with the DXe transmitter, but it won't allow you to expand outside of the Nano QX without jumping through hoops. Step up to the DX6e or DX6 - you won't be disappointed.
