I was wondering if anyone else is kind of frustrated with all the different brands and protocols as far as the 2.4Ghz radios go. We used to have only to deal with upper shift and lower shift and 11-60 channels. Now we have 2.4Ghz and no two radios are the same and Rx's aren't interchangeable between any 2. We have FASST ,FHSS, Spectrum and Tactic and all the others to boot. That's why I kinda stuck to Airtronics as the RD's will fly anybodys RX as well as PCM. The only major player is the Orange RX from HobbyKing that will use Spectrum. I personally like Airtronics and Tactic as they are very easy to program and Tactic is fairly inexpensive. Have not tried the Orange RX as I don't like Spectrum protocol much. Airtronics is kinda expensive for their RX's so i limit whant i get for my RDS8000. I have stuck with the FM units I have as no one has them so I don't get hit and I have never had a issue with them ,(knock on wood!). Any ideas and comments?!
