thx outdoorhunting......think I've figured it out,just not use to such idiotic type of manuals,I guess you get what you pay for.Being an ARF
putting pics here is a last resort,but thank ya the same.It looks like the plywood planks that I was curious about seems to be the Aileron servo
mount support brackets,which doesn't slip correctly in the wing....not what I'm use to.....I know....sanding will not fix the cure. Just not
use to such a product like this.Anyway.......pls continue with any help you can, thx for all and God Speed.

rgds,
Perry
