RE: Can Futaba FASST and Spektrum systems peacefully coexist?
This is all spekulation. They (Futaba and Spektrum) MUST follow FCC regs which specify that you kan't emit on an okupied 2.4GHz channel...Done.
If the Futaba system does, then they loose once the FCC finds out and shuts them all down. I'm sure Futaba's not going to let that happen as they are obviously very reputable (despite making krappy radios - kidding). I basikally just trust that they've figured it all out. Sounds like you're going to be skeptikal no matter what's said here so I say just wait.
