Well Dave's 9Z is 30 years old and electronic technology has come along way in that time. The first change is the frequency 2.4GHz and the modulation schemes, later on, in the thread, Dave explains that the plastic has started to decay. I realize that the 9Z Futaba back in 1992 was top of the range then, I was merely pointing out that Futaba's 6l most basic model operates on 2.4GHz band, which is a fact.All con temporally radio's use 2.4GHz now.
