Sometimes a hard landing means you’ll need to repair your indoor flier. For models that have plastic struts and other fine attachment points, Bob Smith Industries’ Foam-Cure is an ideal repair adhesive. Squeeze out some glue on a notepad, use a toothpick to apply a very small amount to the affected parts, and tape them together for about 10 minutes. The adhesive dries clear and flexible—and it is foam-safe.
