Now I've been working on a project called the BAE 844 (top pic) which was to have FASS, but after seeing the Gulfstream I'm now thinking of expanding it. Sometime ago I bought a couple of sets of the cheek scanners found on the RC-135's, I'm thinking that either joining two of the parts for each side to make an even longer one, or have one scanner before and after the wing on the fuselage sides.
The BAE 844 was based on the A310 and my project is in 1/72. Bottom pics shows some of the development I've been doing
