Shippy, the A and C models arent that different to the B. The A and C do not have a lift fan and thus do not have the panel on the spine of the aircraft for it, yet the C does have a wider wingspan for carrier ops. The difference in FD scale wouldn't even be that noticeable.
Also, just wanted to say thanks to those who appreciate my drawings. Right now I only have this and the V-22 rendering, but I look forward to drawing more and learning on how to draw utilizing the FD scale.
