p51 Thanks for your comments and coach joe, you are right about likely getting help here on the forum but I am not confident of my own skills. Merlin, the minimum radius is not specified but my guess is that it will not make sharp turns. In reality many of these are articulated to go around corners but this model is a solid frame. I would guess it might make 072 but unlikely to make 0-31 or 0-27 but I have not really given it a full try as yet.
