The Rudder assembly needed extra work, the whole system is too low, into the pipe, removed 3/8'' on the horn /rudder post, also removed the servo plate and replaced it with 5/32'' 5ply, c/w blind nuts for the servo, and raised it a 1/2''. I used just one servo rod, but am not happy with the amp. draw and binding, will remove and go with the suggested pull pull.
