Yeah I thought to myself, the time it's taken to figure out how to cut a foam core, I could have already finished the built up version!
Well I've never used this method
before, and the plan doesn't provide the individual rib templates, only the root and tips. The fuse actually calls for foam between all the formers, then the final shape
is sanded out of that foam. I love a good learning experience! Tonight, I joined the stab halves with a 3/32" piece of ply for a spar, then added the 3/8" hard balsa
T.E. Also installed the control horn blocks and the elevator L.E. All in all, I'm pretty happy with this method.
