So I cannot use KO with Futaba at all??
My magnum senior is FM/PCM, it was the top of the line futaba radio before they came out with the 3PJ. I was looking into the EX1 because of its price and quality... but now that I know I can't use it with my existing recievers, it might be better to save up for a 3PJS. I don't know, I like the EX1's shape. It seems like it would be more comfortable and less top-heavy. I'll have to try it out in the hobby store.
