I had to re-order my plans from AMA, but they matched the parts I had fine.

The torque rod probably fixed the problem. Every connection adds a tiny bit of slop to a control surface. The bellcranks added basically three more connections, which left them just too loose. (one for each end of the bellcrank, and one where the bellcrank attached to the airframe.)

It is possible they modified the kit? Mine would have been a few years older. (It sat around half finished for a very long time.)
