Chief - Yes, the same plywood stayed in, just punch out the factory stuff, insert the 1/4-20 brass insert's, get some epoxy in there and other area's of the fuselage. There will be no binding with the tube's, I thought the same thing, and addicted to the "old way". Put two servo's in the rear, instead of tearing the plane apart. If I was going to do that, cut the bottom of the fuse, section's between each former, go in and clip. You can see how I had to insert the elevator pushrod on Intruder #1, from the back, it is a little tight back there.

Each plane I recovered, the fuselage, tail, has been glassed.
