I've been using the RDS800 for about a year now, always liked the airtronics programming and it was a simple switch to go from my RD8000 72Mhz to the 2.4 system. Now I am terribly dissapointed in the radio, my faith is gone, the RDS8000 quit transmitting , no explanation, the computer works but it won't talk to the Rx. Tried the SDG 5 ch and it will bind but I need all 8 CH . Up the creek without a paddle.. Thankfully my 72 Mhz system still works.And we are in the prime flying season...
