Having set side by side the two unbuilt kits' hull (a friend's Anigrand and my RC), while being "only" 30% longer, the RC looked 2 times bigger !
The Anigrand kit is a difficult but very nice kit (clean, well cast), the RC is far more complex and needs more work (casting so-so (bubbles, aging molds...), recommend to add of an inner struts)
Looking at the detail, the RC is closer to the ESB studio model than the Anigrand.
