I see nothing wrong with having more than a few bends in the wire going to the throttle. Assume we are refering to 2-56 wire. The throttle load on the wire is extremly low so unwanted bending is minimal. I use thin "bailing wire" to figure out the best route for the rod, then I bend the rod. Use a "Z" bend at the servo to keep the rod from rotating, and a nylon clevis at the throttle arm.
