Thanks for the input guys, really appreciate it.

dbsonic, I have at least 1/4" clearance, the pipe is not going to exit the center of the fiberglass exhaust cones, in fact the exhaust ends of the pipe are so close together I almost have to cut into the fiberglass cone. I can cut more off of the rods, and I will do that to get as much as I can.

Keith, I can laminate the stab servo mounts with carbon fiber cloth or I could use .040 G10, do you think if I lay some carbon fiber cloth over the ply that they will be fine?
