You'll want to search either for the Goldberg Eagle II trainer or the Goldberg Falcon 56 trainer; somebody got their fowl fouled.
There is a very thorough and detailed review of the Airtronics RDS8000 right here on RC Universe you can check out:

The folks at the AMA also reviewed the RDS8000 for Model Aviation magazine and the AMA's Sport Aviator web site:

I was a happy Futaba 7CAF owner when I decided to make the jump to 2.4Ghz. I was going to stick with Futaba, until I noticed how much more reasonably priced extra receivers were for the Airtronics radio systems. I now own two RDS8000 radio systems and about 14 Airtronics 2.4Ghz receivers. Picking Airtronics has saved me a small fortune on extra receivers, and the systems have been bulletproof for two full years now. No lockouts, no brownouts, no lost receiver bindings, no glitches. I'm at least as happy as the two guys who wrote the reviews mentioned above.
