So my lack of posting is mainly because of two things, I'm working of a pair of Babylon 5 projects...and Cyberpunk 2077 can be a little addictive when you get into it. The first project is about 50% complete while other is about 80-90% complete
So in Star Wars we have the R-41 Starchaser and then we have the R-60 T-Wing, so somewhere along the line the R-40 Series developed into the R-60 Series.
