Fear not the Dragon 251 indy track. Make this easy little jig with 2 strips of balsa glued to and piece with the space just wide enough to hold the guide horn snug. Assemble all the links then go back with a tiny drop of glue in each hole for the pad. Fully workable tracks in a heartbeat.
A little heads up. When you glue in the front axle, do it with the wheels on and, most important, on the tracks as shown. If not the front wheels may float in mid air.
