Folks I finished re-wiring my arducopter last weekend and just wanted to share a photo as I am particularly pleased with the final routing scheme. This may be how everybody has done this but who knows perhaps it may help someone with their first build. I have seen some variability in build approaches which is why I like this group. Plenty of good ideas and innovation. As an engineer I like to be precise and improve reliability.
One thing I just came across is optocoupler connectors for the ESC to APM signal from a German company YGE as a cheaper option instead of using actual opto ESCs. I hope to give these a try in the near future.
