Here's another Futaba site with an excellent history of the company.

FWIW, I am using a 3PM FASST 2.4 system in 8 boats, 7 fast electric and a Insane gas cat. Flawless in every one.
A quick expansion on what Russ was saying is that there are three major methods of doing spread spectrum.
Futaba uses a dynamic frequency hopping scheme which changes the "channel" every 50 ms, or 500 times a second.
Spektrum Brand and JR use a system that selects two channels and locks on those. It will then switch between the two if one sees a high noise signal.
The third, used by XPS, locks a single channel and is supposed to hop if the noise floor gets above a certain level. Some testing has shown that it does not actually hop, but just slows down in response.
Here's a great spread spectrum reference:

A little technical at times, but lots of good info.
