Won't matter how good your servo or linkage is.
While yes I agree with you it looks as they may have learned something from this site,
My shafts came attached to ply with a outer support of honeycomb then topped with 1mm carbonfiber
I did cut into the elevators on both sides of the pivot point. The filled holes in the honeycomb to lit the bolts pass through without contact so I could see the ply
There was also triangle peace of balsa attaching the shaft support to the root peace of ply that the main shaft goes through.
I still added some basswood to add support, aropoxy the spaces around the bolt holes and honeymoon, and added hard wood peace with holes drilled in to support the Bolts over a wider area.
