I can speak from personal experience when I say that Futaba lies when it comes to asking the question about whether or not a radio is being discontinued.
I spent several months looking at and investigating the Futaba 9Z WCII a number of years back. There were consistant rumors about it being discontinued which Bax (Bill Baxter at Hobbico) as well as the other Futaba sources I contacted, denied the radio was being discontinued. It was also mentioned that Tower had a 30 exchange policy so if the radio was in fact discontinued within 30 days I could swap it out.
So I ordered the radio and three weeks later the 12Z was announced along with the 9Z being discontinued.
I contacted Tower about returning the radio on the 30 exchange and they said ''sure, send it back and we'll swap it out for anything in stock.'' I told 'em I wanted the new 12Z radio and would pay the price difference, they told me that the 12Z wouldn't be there for a couple of months so I could not swap the 9Z radio since ''the 12Z is not in stock and the thirty day exchange policy only applies to in stock items.''
As for a radio not being discontinued but Tower simply choosing not to carry it? Seems way far fetched to me since Hobbico owns Tower as well as the Futaba import/distribution rights for the USA and they own numerous other model related companies.
So don't put any stock in whatever you see on a webpage, I was kind of surprised that Bax confirmed the rumor but in my experience if there are this many rumors floating around about discontinued radios, you'd best listen if it's important to you....
