I have just realised that i run the local village hall, slow aint i.
so.
take one sheet of 6mm Depron.
Mark out the top view of the model straight onto the foam and cut out.
then cut the two vertical fuselage halves and glue it all together.
Add some 1.5mm balsa strips to the leading edges and again to the hinge lines.
needs hinging and fitting out tomorrow for a weds maiden.
all of an hours work so far and £2 of foam and glue.
