Hey group! One of my next upgrades will be my radio system. I'm leaning toward the Futaba - 8J, 10J or 14sg. After looking at the Futaba website, I was completely unable to really comprehend, in layman's terms how these compared. It seems that the 10J is actually less than the 8J in a lot of places. Any recommendation? Briefly, do you know how these compare or the advantages from 8 to 10 to 14? I would like to have a unit that can be upgraded as I progress past the Phantom but that's not a requirement. I would be interested to hear your experience/advice with these! Thank you!!
