I have put together the engine box and glued it to the fuselage with epoxy.
i have also added to re enforce the box to the F2 some triangle balsa wood around and at the under neath of the box.

After i epoxied the fire wall to the engine box i have a dded as an extra security i drilled some 2mm holes
all round the fire wall and added had wood pins with wood glue.

I cut flush all the dowels and sanded all the engine box smooth to add the fiber glass cloth to the fire wall this
will make it stronger and fuel proof at the same time.


A very thin fiber glass cloth from fiber tech with 1 hour epoxy dose the trick.
