J one simple suggestion that I did on my CMP Fw190 bash , very easy to do at this point in your build .
1)go to the hobby shop , buy some white plastic tubes slightly bigger then your wooden rods .
2)cut some 2" and even 4" lenghth
3)slide them over your wooden dowl pushrod and support the plastic tube by glueing wood braces to them and the inside if the fuse .This will serve the following purposes , it will prevent any chance of flexing , it will keep the rods 100% straight under servo load and air pressure load on the flying surfaces .
I did this near by servos and cut a small panel out of the bottom of the rear fuse , added the supports and put the panel back in place .
Just a suggestion , good luck
