OK...I'm glad you brought this up...cause I have had a nagging question in the back of my mind about this for some time.

(Also, I'm not trying to start arguments...just gathering information....it's also not a debate between two products....both attempt to do the same thing through different means)...

anyway. so if we don't look at the redundancy aspect of your product....and just look at the fiber optic portion....are we really gaining much since we're still left with 2 copper wires for power?

The culprit is allways the signal wire and not the power wire. You can use the ignition battery to power your throttle servo with the fiber Optics as long as this servo is in the engine box. This way, the only thing going back to the receiver is the a light beam going through the fiber optic cable.

I understand the fiber-optic signal line concept and agree its the best way I've seen yet to truely eliminate noise "IN THE SIGNAL WIRE"....but isn't it still possible to pick-up RF noise through the remaining 2 power wires running to each servo?

Again, no because with this setup the decoders/servos have there own battery so there is no physical connections between the servos and the receiver/s. Another benifit is if your wild with your 3D and draw a lot of current with the servos, the receiver/s never know it since you don't have any servos connected to the receiver/s. Also the receivers have a much cleaner signal since they operate in a much more linear fashion. You can power the receiver with as little as a 300 ma battery and still be good for 10 hours or so.

Are the power wires isolated in such a way inside the RX that any RF noise picked up is not an issue? This is the only explaination I can come up with that makes any sense to me.

Again check the last statement. Your servos are not connected to the receiver.
Another thing to consider, you signal voltage coming out of the receiver is at 4 volts at best, and this why a lot of people have been having problems with ganging up more then 1 servo on the one extension. But the Fiber Optic setup, you get the full 6 volts on the signal right at the servos and this has been tested with 7 large digital servos with no ill effects whatesoever.
If that's the case, then your product makes a lot of sense to me...and I have considered it's use in my 35%'s. It would probably be used with the emcotec unit....the emcotec box offers a lot of other features I want and need beyond redundancy and signal filtering.

OK, but mine replaces all signal wires with fiber Optic cable (optical isolation) and they are good for up to 200 ft.

no servos connected to the receivers.
