[quote]QUOTE: <i>Originally posted by Leon Silverman</i> <br /><br />Intermountain recently announched they were coming out with properly articulated AC-12. This makes it distinctive from other mass marketed versions of this type of engine. If Athearn's Big Boy also sports true articulation, it will also be distinguished from other versions that have been available (except for Bowser). If the model Big Boy mimicked the flexibility of the prototype, it could not negotiate an HO curve tighter than a 42" radius. <br />[/quote] <br /> <br />The old Tenshodo Big Boys and Key models would go around 30" curves and I would hope the plastic models would have more tollerance in the lateral motion. 24" to 30" might be the minimum if the rear engine was not hinged like the Genesis Challenger. <br /> <br />The Intermountain will probably need 26" to 30" curves also. <br />
