I think the R/C radio industry is on the cusp of change again, at this moment. I think the Spektrum DX7, DX6 and radios like it operating on 2.4 GHz is where the future will be. In a few short years I can see radios operating on the 72MHz band being as obsolite as the old 72.bla-bla color & white frquencies were in the late 80s.

Is the change necessary? I don't know! Is it coming? I think so! Does it mean the channel frequincies radios will be selling cheaply, it certainly did in the late 1980s! Sorry, this response is really no help to you Pitch 19!
