How much of an angle are we talking about here? I've never tried it myself, but on the surface it seems like a pull pull setup operates in a 2 dimentional plane. It doesn't matter what angle the plane is on, the geometry of the mechanics will remain constant. As long as you remember to make sure that the distance between the clevises at the control surface is the same as the distance at the bellcrank, (that parallelagram again) you're in business.

OK, now somebody will come along and point out how stuipd I am, and give you some actual good advice.

BTW, I very excited that I got to use "geometry", "2 dimentional plane", and "parallelagram" in conservation. Even if it is just a cyber-conservsation

BTW, instead of "agua" or "water" you should say "unflavored-clear-wet"
