RE: Audax F3A - new project for 2013
Thanks a lot, reading all the nice comments is really encouraging.
The next step was to assemble the fuselage mold plug from the CNC machined parts. From this point on, i worked together with my friend Horia Florian; he has a lot of experience with composites and his work includes a full scale glider.
As mentioned before, the fin was a little flexible, so i added a plywood former at the back to solve the problem. The tip was cut off and later replaced with the balsa milled part.
We used an aluminium profile on the center line of the fuselage mold plug to make sure it stays straight and stiff. Since the fuselage and canopy were milled in 1 piece, i had to design a jig for separating the canopy. The jig was laser cut from MDF and after using some filler and sanding, the result was pretty good.
We also glassed the mold plug using 2 layers of 160g FG cloth.
