Hi Dep... I've been reading your posts and opinions now for several months. Just gotta say Hi.
In my humble opinion, torque rods, while a pain to deal with during install seem to be much better in service than the wooden joined elevator halves. I am learning 3D flight and with the large surfaces, and high surface travel, there is less twist between elevator halves when a torque rod is used. If a good sized rod is used, they just dont offer the same twist side to side that I have experiences with the wood. Of course a one piece elevator or dual elevator servos is better though.
Just my $.02
