Installing the 6mm carbon spars:
I put some tape around the scalpel blade 6mm from tip as a depth guide (which I’m proud of!).
Cut slits and pushed spars in & glued in place with cyano (superglue)
Takes a while to dry properly.
Found a FatYak on this page – I like the ailerons, cut similar to the tailplane
