I ended up splicing carbon rods together by using a short length of brass tube as a coupler, CA'ing and crimping the ends in place. I cut the plastic sleeve and determined how much movement was needed for the surface actuation and separated the resultant two pieces by that distance, plus a little for good measure. I then joined the sleeves together using a larger diameter tube which allowed the brass coupler to slide inside of it, and still have the pushrod supported through its entire length. If you arrange to keep these couplers forward of the CG rather that behind it, it'll be that much less weight you'll have to compensate for with nose weight.
