"Simplify, then add lightness"
I have Hitec which uses 5.5x2.1mm, and everything I see says that Futaba uses 5.5x2.5mm. Those are two common sizes for 12v adapters, and the only difference is the diameter of the hole in the center and the pin on the radio. It is really a pain as about half my 12v electronic items use the 5.5x2.1mm and half use 5.5x2.5. I bought a bunch of adapters off ebay to go from one size to the other.
