The length of halfspan is 900mm. I glued 3 pieces of 6mm widex1mm thick carbon fiber stick. Its only 750mm long, so I spliced it with pine I recover from used packaging material then I add some fishing line at the splice.

Inserts for the engine mount hard point. Made from imported Birch (or so the seller said). I probably shall use harder wood, but this one is already harder than the ply. I glued them to the ply with some 90mins epoxy.

glued with carpenters glue and tacked with CA, then I saturate some CA to wick. I might regret using balsa for the flap hinge with the plastic robart hinge. On my last build the whole right aileron came off !!! Somehow the hinge ripped off from the wood.

Some progress today. I am now thinking of best way to align the tail without proper tools :) The fuse now weight around 280 grams. The front part is quite sturdy and stiff.

i fill the seams of the join with some epoxy so the plys will soak in, it was just tacked using CA. Then I glued the striangle stock with carpertens glue and tack it with CA.
