Otherwise, these foam holes will begin to enlarge. The CA hardened them and this setup works great and is easy to install/deinstall.
I was planning on going the CF route as well. However, I was walking outside to put the plane in the air and I was too impatient to go back inside and cut the rod that was sitting on my desk.
I was standing next to a bucket of dry wall screws and thought.... hmm... this will get me in the air faster. I should probably go back and replace the screws with the CF rod
