41/2hrs later and another change to the shell. I am hoping it will look less like a lump and flow better with the rest of the car.
To achieve is I cut out most of the back to make room for the chute, this allowed me to reshape the back slope of the body. I cut the part that shrouds the jet cone and moved it up 8 scale inches, so it now sits on top of the body. I made a box for the chute then laid down .020x.125 strips of styrene. I will back fill the shell with c-channel strips to strengthen it for the filling, sanding and shaping process.
I also sculpted a another chute, I think this one looks muck crisper. Although it now may be too boxy looking.
Thanks for checking the progress out
