hello,
I guess by now you should have the answer but anyway....
I have little knowledge on Hitec radios but if any radios that is cheap then it may not have all the programable function or advance features comparing to the highends yet still have few switches for servo adjustment..
Basically, in any radio supporting 6 channels then it can support less channels such as 3, 4 or 5 channels without changing XTAL frequency in both TX/RX. If you would to have accidentally bought a 7 channels then your maximum channels is still 6 channels.
Some users have tested running Futaba TX with other brands of RX. In my opinion best to stay with one brand for TX/RX.
For 2.4ghz it's still the same thing apply and make sure your frequency is lock and tested properly.
Lastly, make sure to test your set up and perform range check everytime at your airport.
Hope this helps.
