Every RC modeler should have a good superglue handy at all times. Mostly this superglue is needed to glue (or re-glue) the tyres on the rims. But you can also do other things with the glue: RC car body repair, sealing carbon fiber chassis plates, gluing defective parts, gluing receiver housings back together, and much more.
Check your stock and be sure to stay nice and sticky!
