RE: 10X vs 9Z
I flew Futaba for about 15 years, switched to the Multiplex 4000 and have never looked back. Sold my Futaba after a few months of side by side comparisons. I have now had the 4000 for almost 4 years and it is still going great, never any problems. The flexibility and power of the programming is beyond compare by the JR or Futaba radios.
