nm. no one seemed very interested. Sorry to waste your time.

Do you know that twisting signal lead pairs helps reduce interferance! That is why the old anolog telepone wires were always twisted, it will not add that much length to the wire and any thing you can do to reduce signal coupling is a plus. It will also help keep it from inducing stray signals in other devices!

Item 12 is not necessarily a good idea unless the wires are twisted. Parallel wires bound tightly together over long distances produce ‘crosstalk’. This is where the magnetic field generated around the wire is picked up by the wire next to it and superimposed on the signal on that wire. I would recommend twisted wires over long distances; the twisting reduces the risk of ‘crosstalk’ considerably. Or you can use screened cables.

lol, this came directly from Skymasters manual. Actually their exact sentence was, "Run all wires neatly in harness. Secure with cable ties". Should I take it off or amend it saying that if you do that the wires need to be twisted? I didn't twist my wires, I did run everything through a Smartfly EQ10 power expander which is supposed to take away some of those problems associated with long leads. Did it on my Boomer with over 100 flights and also on my new Skymaster F-16 1/6.
