I Recently Aquired A Nice Little N Scale Atlas Dcc Engine And Some Misc Cars . I Wondered Into My Hobby Shop And Bought Some Flex Track . Im Used To Ho Scale True Track Snap And Fit Stuff, But This Ones Going To Be Serious. What Is The General Rule On The Radious Of The Turn . Im Sure The Cars Will Bind If Its Not Within A Certain Tollerance . And Also , What Is The Best Way To Join The Flex Track , Do They Make Joiners Or Do I Solder Them . And Lastly. Can You Cut To Fit In Certain Sections . I Notice When You Bend It One Rail Is Either Longer Or Shorter Than The Other . And If You Do Cut It , What Is The Best Tool For The Job... Thank You:d
