I think it would be prudent to put a big warning in this document that the device you describe is illegal for use in a FIRST competition.

*Well, we don't know for certain that it is illegal this year, but I'd be willing to bet money on it. It is a safety issue, plain and simple, to have a custom circuit device "in between" the RC's PWM output and the speed controller. It will totally defeat IFI's robot disable functionality.
