Was in the hobby shop this week and one of the guys showed me this flat carbon spar, super thin probably 1 mil i guess but it you cut a slit in the foam and then glue it in makes the foam incredibly strong. Sure a lot of you guys know it already but was great and relatively cheap way to strengthen the foam especially on bigger models i would imagine. tried it on a new tail section for version 2 of my frankenstein plane and worked great.
