I certainly wouldn't want to use this application on a large amazingly scaled jet powered F-14 Tomcat!
I was taking that point for granted....
Typically 40-60 size sport aircraft such as pattern/classic pattern aircraft and aerobatic aircraft like your Ultimates and Extras, your Kaos and Stick.... etc.
If properly installed, torque rods will not give you problems.

I had a .60 sized Kaos that had terrible aileron flex with the stock torque rods. The installation of dual wing servos allowed me to put the push rod in the center of the surface where it belonged. On long ailerons, it is difficult for the torgue rod to hold the end of the surface in position. Unless you use a very long torque rod.
On Q-500 racers though, the torque rod is better. Cleaner for faster speeds. Takes a lot of work to set them up tight without slop though.
