i am relativly new to rc flying. i have a spectrum dx-6 and i also have some 72 fm radios i was wondering if i should just use 2.4 or are the older 72 radios still ok to use? how prone are the 72 radios to glitching?
I have flown with 72Mhz for over 30 years. I switched to 2.4 in 2007, but used both as I gradually replaced my 72Mhz Rx's with 2.4 versions. Now, I fly 2.4 radios exclusively. There wasn't a year that went by where I didn't have to track down the cause of glitches as a result of RF Noise. Then there were long waits at model meets for the Frequency Pin. At the flying field, most everyone paid attention to Frequency Control, but it was wise to make contact with anyone who was on your Channel so that an accidental Shootdown did not occur. There were times when random Frequency Conflicts occurred, on certain Channels.
Is it safe to fly 72Mhz? It depends upon where you fly, how many others fly there on 72Mhz, are there any RC Ground vehicles in the vicinity that you do not know about, and are they using Channels on Air Frequencies because so many high end 72Mhz transmitters are flooding the market, at cheap prices, as they are replaced with 2.4 radios.
For me, 2.4 has been a blessing. Believe it or not, we had two incidents at our flying field, last year, where only two pilots, on 72Mhz, showed up, both on the same Channel, and one shot the other down because he did not grab the Frequency Pin before flying, and the other did.
A DX6 is an early Spektrum radio using DSM. It came with the AR6000 Rx and that is all it is compatible with. I would replace that with a DX6i, DX7S, or DX8, in order to be able to use DSM2/DSMX and be compatible with all the Horizon BNF models. You can still use the DX6, but you are limited.
Some that fly FPV aircraft use 72Mhz because they can get more Range.
