I started with Airtronics in 1989, or maybe 1990 and have never looked back. I have had great results with their customer service, and Jack Albrechts programming advice on my radios sine the late 90s? Has been invaluable. I'm using the RDS8000 as my park flier radio and two SD-10Gs as giant scale radios. I really like the stick switches and flight modes.
If I can put in a vote, I hope future radios have options for a few more channels, the SD-10G is so versatile that I sometimes run out!
