What John Walter suggests is the most common way to do it, and works well. I endorse it.

This also works: fix the tubing (with push rod inside) to the external fuselage at one end, then pull it tight at the other. When it's tight, CA the other end. In the one case I have had of looseness inside (I could hear something banging when I shook the boom), what I did was stuff a packing peanut down the boom. I've done push rods this way on many airplanes (including my two, present Blaster 3's; and a 2-meter Dove I found in 2009) and nothing yet has ever come loose in flight or otherwise.

It's an esthetic thing for me. The best bet is still to run the push rods outside: you can see them, they are secure 100%, there is no measureable drag.

Good luck!

Yours, Greg
