Swapping crystals between identical transmitters???
DBCherry: Actually, when I considered it I did a lot of checking. LHS, other club members etc. I got a lot of opinions either way, but finally was told that Futaba does, in fact, have a high/low issue. JR on the other hand does not. I have almost 40 flights on my Avistar where I changed from the 52 to 25 and not one single glitch, dead spot, range problem etc. I am not saying that I am an expert, I am far from it. But it seems that I had correct information when I made my decision. I don't mean to be vague, but I honestly just can't remember where I read it or who told me.
