Academy CH-46A/D kit questions

I haven't built a helicopter in a long time and I'm thinking of building this particular kit.  Shelf space is a problem, however.  Does anyone know how wide the rotor blade assembly is (from one rotor tip to the other rotor tip)?  I'm not sure I can safely display this model with the rotor blades deployed.  A British firm (Scalewarships) sells a folded rotor aftermarket kit, but I can only find it in England and nowhere in the states.  And, any ideas of where to buy aftermarket machine guns for this model of helicopter?  Kit reviews state that the kit guns aren't very good.  Any help would be appreciated.  Thanks.!
