I don't have a PIC handy - but this is easy to 'splain. I have a hole in the leading edge of my wing. In that hole is a 1/2" section of fuel tube. Then I used antenna tube & piss-thin piano wire. I don't know the diameter of the wire, but it fits easily in the antena tube & it's plenty stiff enough to run the throttle. BTW - the fuel tube is a tight fit in the wing-hole. Drill small & ream to fit... That's how I did mine - works fine. Try it - if it don't work - it was just a bad idea...
