Hi guys, i'm back with some little news:
- i made a cardboard prototype of the right part of the diffuser (in black)
-i used this prototype like matrix for create the final glass-fiber panel
-i used a sheet metal with C profile with the scope of fix the panel at the spar
And this is the final result:
Now i'm testing this panel on the road (bend, twist, vibration ecc) and after that i need to putty it and paint it matte black.
