Sickle fuse stiffness

When looking inside the fuse of V2 and comparing it to JLK's photos of V1 in the Electric F3A forum it is obvious that V2 does not have V1's fuselage "deck" that ran from the nose ring all the way down past the wing tube and provided the rudder servo mounting location. V2 also doesn't have the diagonal side braces in the nose area.

Just wondering if this means the fuse needs a little reinforcements at various locations to make it a bit more tortionally rigid, and if so where? What got me thinking about this is Mastertech's report of his canopy coming off easily, and I associated this with the possibility that the V2 fuse is not rigid enough.
