I finished the DEPS and completed the pull pull cable exits
at the same time. Once the tubes had been located I tack
glued them in place with thick CA.

I then made 2 light ply and balsa fillers to fill in the tail servo
holes and glued them in place with epoxy from the inside.

I used epoxy mixed with milled fiberglass to coat the inside
of the tube exits. I gained access through the rudder post
I had removed earlier in the build.

Once everything was dry I sanded down the tube exits flush
with the fuse sides.
