Spektrum Futaba issues

[Sesame]

has any more come to light re: using these two systems in the same proximity.

I was looking for the thread in which the alleged issue of futaba blocking spektrum when its first turned on was mentioned, but I didn't find it, maybe I imagined it. Anyway I was wondering if anyone has heard anymore one way or the other as the first Futaba 2.4 has just appeared at our field.
