The 6EX is basically the same in 72 MHz and 2.4GHz versions probably due to trying to get something on the market to compete. Hopefully Futaba will have a few upgrades in the 7C when it comes out but I haven't seen anything yet on this. Price is so close to the 6EX I don't see why anyone would ever buy the 6EX over the 7C again. Note: Not a complaint.
