Did you crash one of your helis?

I do not think any receiver would work if you have broken insulation and you short circuit the wires...

of course, that's what I would expect from a redundant part that's intended to improve reliability. The satellite on the wire will fail, obviously, but it's not allowed to kill the whole system.

For example, take a redundant dual-battery receiver. It still flies if one battery fails, that's the idea. It's extremely reliable, because it's unlikely that two batteries fail simultaneously on their own. However, the likelyhood that any of the two batteries fails, doubles in comparison to a conventional receiver.
Basic Engineering 101.
In other words, since losing the radio path with three antennas (main box + 1 satellite) is in a heli much much less likely than a wire rubbing through, adding the second satellite reduces reliability and thus achieves just the opposite of what it was intended for.

This for example is what you'd use just about anywhere but the toy industry if it's reliability you're after.

Then, if the cable of each "redundant" satellite suddenly becomes mission critical, I'd expect them to use wire that ages more gracefully than the one I've got. The heli is less than a year old.
