The transmitter antenna wire has a little plug in on the end... I think the rx is a plain copper strand wire soldered to the board, like most rx's.

I have run spectrum rx's with different length wire and never had a problem. I can't imagine that a 4-5" length would be bad... I have to assume that the 3.6" spec is an minimum length, and anything longer would be ok. But the way it's mentioned in the manual makes you wonder. I think a lot of guys were measuring from the board, back when it first came out and was a new thing.
