Tamiya cars have step screws attached to the plastic parts and they are very easy to fall off. So are the kingpins…
Sometimes a thin zip tie can serve as a quick fix. However, the best way to truly secure the step screw is to first inject hotglue into the screw hole. This will make sure it won’t fall off that easily.
If you do not have enough step screws, regular screws can be used but you need to use hot tube to wrap around part of it so to facilitate rotation.
As an added security measure, apply super glue on the screw thread.
