Okay. Lets just say, for the sake of argument, you epoxied the crap out of a couple pieces of balsa and attached them to the inside of the wing (retract servo mount). After installing said servo and testing it out, you realize the servo is moving around more than it should be. After much investigation (and stumbling across the correct pieces), you figure out that it's moving because you epoxied the wrong pieces of wood in there to mount it to. So, now you've got two pieces of wood in a hrd to get to space that need to be removed.

Again, I haven't done this. Just wondering how you would handle the situation. [&o]
