I'd be interested to hear your approach. I did it this weekend, but went for a very quick and dirty method of feeding a 3.5mm line down the core of my mainsheet. Effective, but leaves a fair lump between the two different sections.

I've always thought it would be good to document this sort of "how to" stuff on a wiki. We set one up for F16 stuff last year, but it hasn't really been used - you're welcome to add content to http://www.formula16.org/wiki. If it ends up with lots of non-F16 stuff on it, I'll happily rebrand it.
