Thanks BurrMan

The blend of the fuselage into the cockpit is quite a soft and subtle which needs to be handled by a variable fillet radius. As MoI does'nt have the option you would need to create it manually via a swept surface. There is also a subtle chine along the spine of the fuselage which adds to the complexity of shape.
I'll post up my attempt at it over the next couple of days when I have time to work on it. I always try and minimise surface joins as much as possible as they often result in messy mesh joints that need to be cleaned up in the polymodeller.
