Hello Billwilner,
I also left a question on the Spektrum site about the availability of the Futaba modules and I got this "official" answer on wednesday the 2nd of March:

---------------
According to our information, The FUT modules will not be available until the end of March.

Thanks,

I got a pré order out for two sets, so just like me, you're going to have to be patient a bit longer

Ciao,
